As a result, we have laid it all out in plain English. Not all of the words and phrases below focus on SEO but we felt that some clarification on web-based terminology would help. So here it is!
You can click on any of the terms below for a more detailed explanation. We have tried to use ‘non-techie’ speak, but should you need more detailed technical jargon we have included links to other explanations too. So grab a cup of tea and start learning about the world of search engine optimisation! P.S. this is a comprehensive list (the most in-depth on the web, actually) but if you have any other phrases that you are unsure about please just let us know.
1 - 10 .
Permanent redirect from one web page to another. The user does not experience any delay as the redirect takes place instantly. Webmasters often use 301 redirects for canonical URL issues and deleted pages.
Unlike 301 redirects, a 302 redirect is temporary. Webmasters may place a 302 redirect while redeveloping a website or to avoid the passing of spammy link juice.
Similar to a 302 redirect but used only for HTTP 1.1.
An error message displayed on the screen to the user when a page cannot be found. 404 messages are often returned if a page has been deleted or the URL has been typed incorrectly.
An expression used to refer to the area seen by the user when they first visit a web page and have yet to scroll down. Also see: ‘The Fold’.
A bidding platform owned by Google. Users bid to be displayed to searchers in Google’s search results. Adwords results appear in a box at the top of results pages, separated from organic results.
An affiliate website exists to sell another website’s products or services. Usually, a referral scheme is set up to ensure that advertisers pay commission to the affiliate website.
A global traffic ranking system provided by alexa.com that is based upon a large panel of users and their activity over a 3 month rolling period. A website’s Alexa Rank is determined through a combination of unique visitors and pageviews. The ranking is updated on a daily basis.
An automatic penalty applied to a site by Google. Unlike manual penalties, algorithmic penalties are automated and are sometimes not accompanied by a message in Webmaster Tools. As such, the reason for an algorithmic penalty can be harder to identify and subsequently to recover from. Also see: ‘Google Penalty’.
A piece of code attached to an image that provides a textual description of the image itself. The user does not usually see the alt text – rather, since search engines are unable to ‘see’ what an image depicts, the alt text works to describe what they depict. Alt text is displayed to the user in the case of browser incompatibility issues. Although it should be used to provide genuine descriptions of images, alt text is often used in cases of keyword stuffing. Also known as: ‘Alt Tag’ or ‘Alt Attribute’.
An open source project driven by Google (and to an extent Twitter) to provide a coding structure that loads websites faster for mobile devices.
The name given to an initiative by Google to provide a web technology that allows mobile pages to load faster. See: above.
Anchor Text are the characters displayed to the user that contain a link. Anchor text is a useful way to input links into sentences and paragraphs without having to include the entire URL.
API (Application Programming Interface)
A set of instructions for programmers to be able to access a particular piece of software. API’s essentially allow other developers to connect what they have designed to this particular piece of software, usually to either include it on their website or power their website.
The practice of rewording an article multiple times, either to be posted for link building purposes or as content for a site. Article spinning is considered a low quality and therefore spammy tactic by Google and other search engines. ‘Spun’ articles are usually fairly easy to spot because sentences are not structured correctly and strange synonyms are used.
An SEO term used to describe the credibility and popularity of a website.
An overview of all the backlinks to a website or webpage. Backlink profile descriptions might include ‘strong’, ‘spammy’ or indeed ‘non-existent’.
Refers to links from external websites that point to another webpage. For instance, if a webpage was to contain a link to this page it would count as a backlink. Also referred to as external link, inbound link or incoming link.
A group or network of websites that employ spam tactics. Gaining backlinks from bad neighbourhoods can associate your website with spam.
Below the Fold
See the definition of ‘The Fold’ for more information. Below the fold refers to the area of a webpage which is not immediately seen when visiting said webpage, i.e in order to view this area of the page the user needs to scroll down.
Also described as spam, black hat SEO involves practices that contravene search engine guidelines, most notably Google’s webmaster guidelines.
Usually uses a content management system such as WordPress, blogs act as sites which document things in a time based format. Often individuals, blogs can be on anything from the musings of a coder to someone who is travelling the world and wants to document their trip online.
Part of the link building process, blogger outreach is the practice of identifying and contacting bloggers, usually for SEO purposes.
Refers to a community of bloggers. Can also refer to all blogs on the web. Much like the ‘Twittersphere’ anything posted on a blog and any engagement on a blog can be referred to as part of the blogosphere.
Recording a website address for future reference. Many web browsers have their own in built bookmarking system.
Also known as robot, spider, crawler and probably many other variations! A computer program which can interact autonomously. When bots are mentioned in reference to SEO it is usually in reference to search engine bots which are used to crawl the web and read or ‘index’ webpages for the search engine. Black Hat SEOs often use bots for automated, spammy link building purposes (see social bookmarking) or to scrape content from other sites.
A ‘bounce’ refers to a visitor to your site that leaves the website after only viewing a single page. Google define a bounce as a ‘single page session’. Therefore a website’s bounce rate is the percentage of single page sessions compared to total visitors. For more information see https://support.google.com/analytics/answer/1009409?hl=en-GB
Also known as brand keywords, branded searches or branded search terms. These are search terms that include the name of a company, organisation. It can also be in conjunction with their product or service. For example, ‘Coca Cola’ would be a brand name, ‘Oracle’ or ‘Oracle ERP’ could also be considered a branded keyword.
An element on a website that displays the user’s navigation on a website.
A link that no longer connects to a webpage. This can be because the page no longer exists and therefore returns a 404 error, the URL has been incorrectly inputted in the code or the link’s code is incorrect.
Browsers store information from websites to speed up processes such as load speed.
A change made to the way that Google indexes content on the web which fully rolled out in June 2010. Google claimed it would create 50% fresher results for searchers compared to the old system.
Call to Action (CTA)
A specific part of a webpage that encourages the user to click on in order to navigate to another part of a website, purchase a product or contact a company. Call to Action usually refers to a button or a number that the user will click on in order to purchase something or make contact but can be as simple as reading more information or watching a video. For example, a classic call to action would be a ‘buy now’ button next to a product on a webpage.
The referenced or designated URL for a page. For SEO this is in relation to choosing a canonical URL for the whole website and 301 redirecting all duplicate pages to this canonical URL. For more information see https://support.google.com/webmasters/answer/139066?hl=en
An anti-spam program to prevent automated programs from accessing the webpage. Commonly found on comment areas of blogs a captcha will ask the user to input data from an image. This is usually in the form of writing the text that can be seen on the image or a simple maths question, e.g 3+4.
Part of MajesticSEO’s trademarked Flow Metrics, Citation Flow is a score given to a URL out of 100 (1 being the lowest, 100 the highest). It is an indicative score based on the amount of links pointing to that particular URL.
Also see ‘link bait’. a link or title of a page on the internet that entices people to click on it. Often used on social media platforms, these links or titles might be particularly controversial or luring. For example, instead of “20 shocking photos”, a click bait article would be “20 shocking photos, No.7 is insane!”. A good example of a website that enjoys using click bait is Vice – just follow Vice on Facebook and you will see why!
In direct relation to Google Adwords or any other pay per click advertising platform. Click fraud is when individuals click on an advert with the sole purpose of cost to the advertiser.
Also known as keyword cloaking. It is a black hat SEO technique where webmasters will attempt to hide text from the user, but make it visible to search engines for the purpose of manipulating the search rankings. A common version of cloaking is to place text on a webpage that is the same colour as the background.
CMS (Content Management System)
A software platform used by many websites which allows those with access to alter or change content without any specific knowledge of coding. There are a variety of Content Management Systems, some are opensource such as WordPress (this website is built in the WordPress CMS). Many Content Management Systems also give those with access the ability to easily change aspects relating to search engine optimisation such as meta data and alt tags without having any knowledge of coding. There are multiple SEO ‘plug ins’ for the WordPress CMS with one of the most popular and highly recommended one being ‘WordPress SEO by team Yoast’.
An SEO concept that is based upon communities. The co-citation concept works on the principal that good websites will link to/speak about other relevant and good websites. There is a lot of confusion in the difference between co-citation and co-occurence. Many believe that co-citation is the ranking benefit that a website (website A) will receive by linking to relevant websites (let’s say website B) which are in turn linked to other high quality, relevant websites (website C). Whilst website A might not have a direct inbound link from either website B or website C, the fact that website A is linking to website B means that it is being discussed in the same community as website B and C. Others believe that co-citation is the ranking benefit that a website might gain from being cited in article along with another relevant website (but not necessarily receiving a link). Whatever the definition, the concept is still relatively the same: being mentioned with your peers is beneficial even if it does not come with an inbound link.
A difficult concept to understand, more information and views:
See co-citation for more information on the difference between co-occurence and co-citation. Co-occurence is based upon latent semantic indexing. Essentially, due to the proximity of certain keywords to your brand name around the web, a website could receive a ranking benefit from this co-occurence even without a direct inbound link. For example, if Yellowball were to be mentioned in an article about SEO training, the fact that our brand name is being mentioned in the same sentence/paragraph or article which contains the keyword (or variations of) SEO training, then we would receive a ranking benefit for this search term.
A black hat SEO technique which involves commenting on websites in order to gain a backlink, without adding any value to the discussion. Comment spam is often automated by bots but can be prevented through a captcha on the website. Comment spam is an obvious black hat technique due to the fact that the comments (and link) are usually completely irrelevant and of low quality. For more information see our explanation of different types of linkspam
In relation to SEO this is where you look at online competitors and document their SEO efforts. For example you research the keywords that they are currently targeting or identify link building opportunities. We teach that competitor research should mean that you have all the information of what the market is trying to do with their SEO and therefore be able to create a strategy from there, it can also save a lot of time!
Usually refers to the text, images or video on a website.
Google’s definition is a website with low quality or thin content.
Based around the aims of a website, for instance an e-commerce website’s aim is to sell products. A conversion can be classed as when a user of the website fulfils this aim. For example, this could be when a user confirms payment for a product. A conversion does not necessarily have to be transactional and websites can have multiple conversion points. A further example would be of a business classing a website conversion as someone calling them or filling in an enquiry form.
See ‘conversion’ for more information. The conversion rate of a website is defined by its goals and is calculated by the ratio of visitors that complete these goals to the total number of visitors, usually given as a percentage.
Data sent from a website to a user’s web browser when they are on the site. This data is stored to track activity and also make browsing the site quicker in future.
CPC (Cost Per Click)
The amount paid by the advertiser when a user clicks on their advert. This cost can vary dramatically depending on the competitiveness of the keywords targeted or the popularity of the website upon which the advertiser is displaying their advert.
When a bot is on a webpage or website. Search engine bots will ‘crawl’ a website in order to index the site. More popular websites will be ‘crawled’ more often by search engine bots.
The concept that a certain amount of time is assigned to a bot to crawl and index a website placing greater emphasis on onsite optimisation.
An automated computer program that navigates web pages via links. Usually refers to bots used by search engines to constantly read and index webpages and websites.
The practice of analysing and improving a website’s conversion rate. This might include larger call to actions, more compelling content or easier navigation.
CSS (Cascading Style Sheets)
The CSS of a site will determine how elements in a the html code will be displayed. It is easiest to think of CSS as the design aspect of programming.
CTR (Click Through Rate)
The percentage of people that click on link or image compared with the amount of people that see the image. In SEO, CTR is commonly used to describe the percentage of people that click on a search result compared with the amount of people that have seen the search result. For example, everything being equal, the CTR for a website ranking 1st on any Google results page is generally considered to be higher than if they were ranked 4th. CTR can also be useful for determining the success of an online advertising banner.
Also known as being ‘removed from the index’, see ‘index’ for more information. If a website has been de-indexed it means that it has been removed from a search engine’s database. This is most regularly due to the website infringing on the search engine’s guidelines. For example, black hat SEO tactics can result in a ranking penalty or being completely removed from a search engine’s index. This in turn means that the website will not be displayed by the search engine for any search terms, not even if the exact URL is searched for.
When a hyperlink does not work. This can occur for multiple reasons, the destination web page may not be working, their may be issues with the links’ code or the webpage containing the link is not working.
Deeplink Ratio or Percentage
The amount of links pointing to inner pages of a website compared with the total amount of links pointing to any page on a website.
Links pointing to a webpage that is not the homepage of a website. Websites that only have links pointing to their homepage may suffer in their ability to rank due to the fact that it may indicate thin content.
The visitors to a website that have navigated to the site by typing the URL directly into their browser, rather than entering the site through referral channels such as search engines or adverts.
A webpage or website that is devoted to listing other sites, companies or organisations. For example, Yelp is a directory.
Usually works on a ‘Pay Per Click’ basis. The use of images or video to advertise on another website. Various platforms facilitate display advertising, one of the most comprehensive of which is the ‘Google Display Network’.
DNS (Domain Name System)
The system by which computers make sense of alphabetical addresses such as www.weareyellowball.com.
A unique address at which webpages or websites are located on the world wide web.
A score assigned to a website domain (out of 100) based upon its ability to rank on search engines, 100 being the highest score. This score was developed by Moz.com, for their definition see http://moz.com/learn/seo/domain-authority
A unique set of letters, dashes and points that make up the address at which a webpage or website can be found, followed by a standard internet suffix. For more information see https://support.google.com/a/answer/177483?hl=en
Domain Name Server
A server responsible for connecting a user to the destination website or address. There is a global network of domain name servers. Also see ‘Domain Name System’.
A page that is specifically designed to attract traffic from search engines, but then redirect them (not the search engine) to another page. Doorway pages are considered to be against Google’s webmaster guidelines due to the fact that they offer little to no value for the user and are created purely to rank for certain keywords and redirect the traffic from those searchers. Doorway pages often utilise exact match domains and keyword stuffing, they are generally poorly designed as well. For Google’s definition of a doorway page see https://support.google.com/webmasters/answer/2721311?hl=en
A term that refers to a user navigating away from (or ‘dropping off’) your site. This can be used to identify issues with user flow and can be accessed via Google Analytics’ Users Flow.
A webpage (or website) that displays exactly the same or very similar content as another webpage either on the same website or on another website.
A form of duplicate content, duplicate URL’s mean that the same content if being displayed on multiple webpages (therefore making it duplicate content). There are multiple ways in which this can happen: printer pages, URL parameters and session Id’s (see http://moz.com/learn/seo/duplicate-content). The webmaster should also choose a canonical URL because www.seotraininglondon.co.uk, seotraininglondon.co.uk, http://www.seotraininglondon.co.uk and all other variations of the homepage would count as duplicate content. As such, all duplicate URL’s should be 301 redirected to a canonical.
E-Commerce (Electronic Commerce)
Transactions occurring using the internet. A website that can complete a transaction online without face to face contact would be considered an E-commerce site.
See linkbuilding for a different method of gaining links. A website can earn links by providing content or design that other websites link to naturally. It is considered to be a sign of high quality content or design.
Also see ‘EMD’ (exact match domain). A Google update designed to reduce the impact of spammy exact match domains released in October 2012.
Used to refer to the constant changing of websites in the search engine results pages. Stems from Google’s constant crawling, indexing and ranking of website across the internet.
An SEO buzzword used to describe content that does not decrease in value with time. See ‘content rot/decay’ for more information. An example of evergreen content would be this index – as long as definitions do not magically change over time!
External Anchor Text
See ‘anchor text’ and ‘external links’. The clickable text on a link pointing to your website from a different website.
A link pointing to a webpage from another webpage not on the same domain/website. i.e if another website were to link to this website, that would count as an external link.
The first Google update which got real air time and caused havoc amongst webmasters!
Links are by their nature ‘followed’. There is no ‘follow’ tag to be placed on a hyperlink, it is only because of the ‘no follow’ tag that links without this tag are referred to as ‘followed’.
See ‘Linkspam’. A manipulative method of using forums to drop spammy links for the purpose of increasing a backlink porftolio.
A suspected Google Update that was released in March 2017 without any official notice. Initial reports pointed towards content heavy sites with a focus on ad revenue being affected.
A different name for a doorway page.
A program used by Google to determine which websites to rank in the search results for a given search term.
A platform which allows users to read and analyse data from their website. Google Analytics requires a piece of code to be added to the website in order for the platform to track the data. Data is based upon visitors to the site and their behaviour, such as bounce rates, visitor flow and location. Best used in conjunction (and linked with) Google’s Webmaster Tools.
Intrinsically linked with a Google + profile. Google authorship allows creators of content to link said content with their Google+ profile. Google trialled Google authorship for 3 years, but on August 28th 2014, John Meuller from Google announced that it would be discontinued. For more information on the history and reasons behind its discontinuation see http://searchengineland.com/goodbye-google-authorship-201975
Also see ‘bot’. A program used by Google to navigate and index webpages throughout the internet. Bots can travel between websites through hyperlinks.
A black hat SEO technique designed to reduce a website’s rankings through penalties (or get them de-indexed altogether). Google bowling involves creating multiple spammy links that link to a website, thus incurring a Google penalty.
A development of Google’s ‘one-box’ concept which was discontinued for local results in late 2014. The carousel appeared at the top of the Google search results and attempted to display relevant results, mostly for local results such as hotels or restaurants.
No longer occurring, the Google dance used to be a time every month where Google would update its web servers and add the new pages that it has identified during this time. As such, during the Google dance there could be substantial fluctuations in rankings. Google now crawls the internet 24/7 and updates its results in real time, therefore making the Google dance obsolete.
Google Direct Answers
Part of the ‘one-box’ approach, Google’s attempt to provide searchers with an answer to their question or search term without them having to click on a result. This information is scraped from sites that they feel have delivered the most accurate result. Heavily linked with Google’s Hummingbird Update.
Google Display Network (GDN)
A group of sites that have available advertising space and have joined Google’s Display Network. Google collate this information and list sites which can either be selected manually by the advertiser or groups of sites which Google will then display the advert on according to the type of user targeted or by cost. See http://www.google.co.uk/ads/displaynetwork/
Google Dissavow Tool
A platform supplied by Google so that webmasters can submit a list of links which they want to be ignored by Google. Much has been written about the effectiveness of Google’s dissavow tool. The dissavow tool is part of the reconsideration request process for those websites that have received a penalty. Links can also be dissavowed prior to a website receiving a penalty.
See ‘Google bot’ and ‘bot’ for more information on the process of Google indexing websites. The Google index is Google’s database of what they have seen of the internet. Google’s bots are constantly crawling the world wide web, reading webpages and collating this information in their index. The development of Google’s index meant that data was much easier (and importantly much quicker) to decipher and return the most relevant result to a search term.
Google Keyword Planner
Part of Google Adwords platform. The keyword planner is a system provided by Google which allows you to check the monthly search volume, competition and average cost per click for chosen search terms. Search volumes should be treated as indicative rather than exact, and competition is either low, medium or high. Geographical locations can be designated, or new keyword ideas automatically generated. Used by many SEOs as one of the starting points for keyword research
Google Local Listing
Created through a Google+ profile. A local listing will mean that you will turn up on Google maps for relevant search terms. For applicable searches Google will display a box with Google local listings on the first page of results.
Google’s attempt to give the searcher all the information they require without having to click through to another website or scroll down. A similar concept to Google’s Direct Answers. A good example of this is when you type an actor’s name into Google and their information will appear on the right hand side. This information might include a picture, height, weight, age, recent films, related information, personal website, IMDB profile, etc.
A penalty assigned to websites that have been infringed on Google’s Webmaster Guidelines. Penalties can be assigned algorithmically by Google’s system or manually by the webspam team. The impact is reduced ranking in Google’s results or the removal of the website from Google’s results altogether (de-indexed).
Google Plus (G+)
Google’s social network, it also provides a platform for business to provide information such as location and opening times.
A controversial term that has not been confirmed. It is a theory that Google places ranking restrictions on new websites for a period of time.
Updates made to Google’s search engine algorithm.
Google Webmaster Guidelines
A set of rules published by Google for webmasters. These rules were designed to help webmaster make their websites more visible to Google and ultimately rank better. https://support.google.com/webmasters/answer/35769?hl=en
Grey Hat SEO
A popular term used to describe SEO techniques that could be considered borderline. These usually involve techniques that have not necessarily been openly denounced by Google but are likely to be in the future. In reality, grey hat SEO is still black hat SEO and should be avoided.
The practice of writing content for a website other than your own. People usually guest blog in order to gain a backlink for their own website (rather than out of the kindness of their own heart!) or to increase exposure for themselves or their website on the internet.
See ‘guest blogging’. A guest post if a piece of content on a website that has been written by a person not associated with that website or company.
Also known as H1, H2, H3 and so on. H1’s are considered to be more powerful for targeting search terms than H3’s, heading tags usually make text appear in a larger font or as bold to the user on the webpage. In layman’s terms heading tags create a title and subtitles for pages. For more information and technical implementation see how to use heading tags for SEO.
Commonly thought of as when someone visits a webpage or website.
The first and usually the main page for a website. It is the page from which the user can then navigate the website. The homepage is considered to be the most powerful page on the site in regards to targeting search terms.
Html (Hypertext Markup Language)
A computer language that is core to the creation of webpages. For more information on exactly what Html does see http://www.w3schools.com/htmL/html_intro.asp
A procedure by which information is exchanged securely between users and websites on the internet. HTTPS works to authenticate websites and encrypt any information communicated between clients and servers, thereby protecting both from being compromised by hackers.
An update to Google’s algorithm released in late 2013 which focuses on conversational search terms rather simply keywords. Essentially Google will look at the meaning behind the phrase to give a more accurate result, rather than just looking at keywords. Many believe that this is in response to an increase in voice activated searches on smart phones. See http://searchengineland.com/google-hummingbird-172816
A link hat points to either information on the same document or another webpage.
A tag used to embed a document within another document. This is used on websites that are looking to display information from another source without the user having to visit another page.
The amount of times something has been seen on the internet. An impression does not count as a click or a ‘hit’. For example, if your website were to be seen as part of Google’s search results this would count as an impression even if the person clicked on a different result. Does not have to be in the search results, can also mean the amount of people that have seen an advertising banner.
Same as ‘external link’. This is a link to your webpage from a different website or domain.
See ‘Google Index’.
See ‘Google Index’ for more information. Indexed is used by SEOs to describe when a website has been crawled by a search engine and subsequently added to their index. Once indexed, Google (or other search engines) will then display your website for search terms that they deem relevant.
When used whilst talking about SEO, information architecture means the structure and organisation of a website. A clean and simple information architecture is not only beneficial for SEO but can also improve user experience.
When someone types a term into a search engine for the purpose of finding information, rather than a transactional or navigational search term.
a page on a website that is not the homepage. An inner page is separated from the homepage by a ‘/’. For example, www.domain.com/product
Internal Anchor Text
See ‘anchor text’ and ‘internal links’. The clickable text on links pointing to the same website.
Hyperlinks that point to a page on the same domain/website.
A Google update released in early 2017 that punished web pages with pop-ups and adverts that are damaging to mobile user experience.
A Google webmaster trends analyst, he is an important person to listen to about SEO.
When a keyword is used too many times on different pages on the same website. Google and other search engines then find it difficult to figure out which page to return as a result to the user. A similar concept to duplicate content.
See ‘keywords’ for definition. Keyword density is the percentage of times a keyword appears on a page or website compared with the total number of words. It is an outdated metric that should not be taken into consideration.
See ‘Exact Match Domain’.
The SEO practice of identifying which keywords will be targeted through an ongoing SEO campaign. We teach that keyword research should be incredible thorough as it is one of the driving factors behind campaigns. Keyword research can be conducted through brainstorming, Google’s keyword planner, competitor research and the autofill function of search engines.
Considered to be spam, it is where keywords are included on a webpage unnaturally. This might be repeating the keyword over and over again, or cloaking repetition of the keyword. Keyword stuffing is easily avoided asking yourself the question, if I didn’t know about SEO would I include that phrase?
A word or phrase that is considered to be of high priority in terms of targeting through an SEO campaign. Can also be referred to as search terms.
Similar to Latent Semantic Indexing, Google’s collating of data in order to understand how people search and how everything is connected. They can then link relevant information and display it on the right hand side of the search results. For example, typing in an actor’s name, Google might also give you other actors that have been searched for and are relevant. See http://www.google.co.uk/insidesearch/features/search/knowledge.html
The first page that a user sees when visiting a website. This could be the first page after clicking on a Google result, or the page that a banner advert links to. Remember, first impressions count so make this page a good one!
Latent Semantic Indexing
A form of computer learning based upon fuzzy set theory. Probably easiest explained as Google learning about relevance between search terms by their proximity to one another on the web. A bit like Google developing a large thesaurus and constantly constantly developing this by looking at which words are repeatedly seen next to each other across the web. For instance, Google will know that link spam and black hat SEO are related phrases because they will both be mentioned in hundreds of articles about SEO. Co-occurence is a pretty similar theory to LSI; they both mean that you can target search phrases without actually usingsaid phrase (in theory at least!).
The practice of producing content on a site that will earn links from other websites. Whilst in an ideal world all content should be produced to ‘earn’ links, most people use the term link bait to describe a certain style of earning links. Link bait content is often controversial, so that its controversy will entice people into wanting to share it.
A common SEO practice, it is where someone will proactively look to gain links for a website. Link building is possibly the most infamous aspect of SEO, see ‘Penguin Update’ for more information. Ironically, whilst most SEO agencies claim to get ‘high quality natural links’ for their clients, by its very nature links gained through a link building campaign are completely unnatural.
See ‘link rot’.
See ‘Linkspam’. A Black Hat tactic where SEOs or automated systems identify websites, blogs and forums in where they can include links in comments or posts, hence ‘dropping’ a link.
The strength of a website in regards to the followed external links pointing to the site.
Also see ‘reciprocal linking’. Link exchanging is where two (or more) websites agree to link to each other either for referral traffic or as part of their link building strategy.
Also known as link farming. When websites are created in order to provide a link to a destination website. They usually do not link to each other in any way, but are built only to link to a specific website. Link farming is against Google’s webmaster guidelines.
Also known as ‘PageRank hoarding’. Due to the rel=”nofollow” attribute (introduced in 2005) which can be applied to links, webmasters began placing this on all outbound links in order to retain as much PageRank as possible.
Also see the definition for ‘Page Rank’. Link juice is the perceived value that is passed from a website to another when it links to said website. Think of it as the SEO power that links have. In basic terms it is the page rank that is passed to a website by a link, the higher the page rank of the link giving site the more link juice is passed. Link juice was traditionally thought of as flowing one way (to the destination site of the link) but the theory of co-citation argues otherwise.
all of the factors taken into account to determine the value of a link to a website. For more information see http://www.searchenginejournal.com/beginners-guide-to-link-metrics/19926/
a type of linkspam utilised by spammers to quickly build links. Link networks can be defined as a group of websites that are linked together. Whilst websites that are connected by links occur naturally, ‘link network’ is most regularly used to describe spammy sites that have linked together in order to increase the amount of inbound links each website has and therefore manipulate Google’s search results. They are often poorly designed websites and can have links from other completely irrelevant sites.
Link Rot / Link Decay
Links are not always permanent. Pages get deleted, information becomes irrelevant and websites alter their content. Link rot or link decay is the process by which links become broken or devalue due to lack of relevancy.
A term used to describe the various link building tactics used by spammers to attempt to increase search rankings.
