Execution

This is where the strategy goes live – combining content creation, technical optimisation and proactive outreach.

Ballet with Isabella

313% ROI from organic search

Client Overview

Ballet with Isabella is a founder-run and owned online ballet training platform providing a range of ballet training videos through a tiered membership structure. The website features a growing library of ballet dancing movements, exercises for strength, conditioning and various recommended equipment.

Challenge

Organic search represented a significant opportunity for Ballet with Isabella once her new website launched as our optimisation efforts began from a standing start. A primary challenge was effectively communicating advanced ballet concepts and terminology into content that is easy to understand for the average beginner while offsetting seasonality seen during the new year.

Key Results

313% ROI from organic search

  • 500% increase in non-branded impressions
  • 985% increase in non-branded clicks
  • 313% ROI for the SEO Campaign

Solution

Throughout the campaign we have been systematically mapping out search demand for any upcoming Classes, Courses and Plans being added to the website and identifying any additional opportunities for already existing content. This has given us the ability to action page by page optimisations and align it with a supporting blog article strategy to deliver great results. We have worked closely with Ballet with Isabella to identify and optimise new class sub-category types and have written supporting content for each.

Outcome

A clear campaign roadmap that takes into account Ballet with Isabella’s existing core offering, new and upcoming service offerings and Isabella’s busy schedule has allowed us to roll out an effective strategy. Ultimately this strategy has enabled us to be commercially mindful while maintaining true to Ballet with Isabella’s brand voice, resulting in a great ROI.

“I recently joined the Yellowball team, and they have made me feel very reassured and relaxed with a big transition from an old developer to them. Their amazing customer service has made the move worth it. I look forward to working with them more and more.”

Uncommon
Uncommon

+1,300% ROI

Uncommon

+1,300% ROI and 50% of all sales driven via SEO

Client Overview

From a single space in Highbury & Islington to a fast-growing network of locations, Uncommon has scaled rapidly by redefining what coworking can offer. With design at the core and wellbeing woven into every element, Uncommon attracts startups, freelancers and enterprise teams alike – offering everything from hot desks and private offices to event spaces and meeting rooms.

Challenge

Uncommon first partnered with Yellowball at an early growth stage – launching with just one site and a bold vision. Over the years, we’ve supported their expansion with a broad remit: SEO-led growth, platform and location launches, design support, paid media, and technical development.

The challenge was multifaceted. We needed to:

  • Increase visibility and organic traffic in a highly competitive coworking market
  • Outrank major players like WeWork and The Office Group across all location-based search
  • Develop a multi-audience search strategy – addressing everyone from solo freelancers to enterprise teams
  • Drive high-converting traffic while supporting Uncommon’s broader occupancy goals across locations

Key Results

+ 100 %

100%

+200% increase in organic users and sessions

  • 50% of all sales attributable to SEO
  • 1,300% net ROI from SEO activity
  • Outranked WeWork in all targeted locations

Solution

To meet Uncommon’s aggressive growth goals, we implemented a layered SEO strategy – one that evolved in tandem with their business trajectory.

Phase 1: Foundations & Local Search

We focused first on local search, optimising each location page for its borough, subregion and service offering. We built robust content frameworks for Londoners searching for flexible workspaces with a specific postcode or area in mind – e.g. “coworking space in Borough” or “offices near Liverpool Street”.

Phase 2: Audience Expansion & Content Strategy

As Uncommon’s footprint grew, so did its audience. We created content to serve multiple buyer personas – from freelancers and startups to scaleups and corporates. Our campaign integrated content clusters around meeting rooms, event spaces, and workplace wellbeing – helping to drive visibility and expand brand reach beyond transactional keywords.

Phase 3: Integration & Intelligence

We worked closely with Uncommon’s internal team to sync SEO priorities with live and forecasted occupancy data. This enabled us to direct organic growth efforts toward locations with headroom – maximising return from rankings. Ongoing technical audits and site enhancements ensured scalability and performance as new locations were launched.

Outcome

SEO has become a primary acquisition channel for Uncommon, now responsible for over half of all tracked sales. We’ve helped them consistently outrank industry giants across all key London locations – driving sustainable growth, high-quality traffic, and measurable ROI.

RSVP Call Centre

RSVP Call Centre

11,650% increase in top 10 ranking keywords

Client Overview

Founded in 1988, RSVP is the UK’s oldest call centre, offering omni-channel service and sales support to clients across various sectors. What sets RSVP apart is its unique workforce of professional actors and performers, delivering communication excellence for over 30 years.

Challenge

RSVP aimed to increase brand awareness and attract new business, as well as recruit call centre staff, specifically actors seeking flexible work between roles. Improving search visibility was key to achieving these goals.

Key Results

2,754% increase in non-branded click-throughs via search

  • 201.7% increase in new users via organic traffic
  • 11,650% increase in top 10 ranking keywords (from 2 to 235)

  • Organic search now drives 66.4% of total new users (up from 38.6%)

Solution

Outcome

Across 3 years, Yellowball significantly boosted RSVP’s search visibility, leading to substantial growth in both lead generation and recruitment efforts.

Plus Rooms
Plus Rooms

+1,405% increase in non-branded organic clicks

Plus Rooms

+1,405% increase in non-branded organic clicks and 104% growth in new organic users

Client Overview

With a portfolio spanning kitchen extensions, loft conversions and full refurbishments, Plus Rooms has carved out a niche in the competitive London residential market. Their focus on elegant, functional design and seamless project delivery has established them as one of the capital’s most respected home extension specialists.

Challenge

Plus Rooms approached Yellowball with a twofold objective: to redesign their website to reflect their premium positioning, and to improve search engine visibility in a competitive space where local SEO was critical. Despite their strong reputation, they were being consistently outranked by competitors on Google, risking missed enquiries and lost revenue.

Our challenge was to deliver a site that matched the quality of their work and to launch a strategic SEO campaign that would improve keyword rankings, drive relevant traffic, and convert visitors into high-intent leads.

Key Results

+ 100 %

100%

+769% increase in total ranking keywords

  • +661% increase in non-branded organic impressions
  • 104% increase in new organic users since SEO campaign launch

Solution

Yellowball launched a full-scale SEO campaign in tandem with the website redesign. The new site was SEO-optimised from the ground up, with technical architecture and key landing pages built to maximise performance from day one.

From launch, we rolled out a tailored content strategy, including blog articles and in-depth guides focused on home extensions, planning permission, and design inspiration. Content followed a pillar and cluster model – helping build topical authority while driving keyword relevance.

To support local SEO objectives, our team developed borough-specific location pages (e.g. “kitchen extensions Dulwich”), showcasing project examples and case studies in each target area. This hyper-local approach proved highly effective in generating high-quality organic traffic and leads from prospective clients searching in their area.

Over the years, we’ve refined onsite optimisation across key transactional and supporting pages, expanded the blog strategy, and continued to drive strong authority signals via outreach and link-building – all contributing to compound organic growth.

Outcome

Now entering the fourth year of our partnership, Plus Rooms continues to see sustained organic growth and a consistent increase in high-value enquiries. Their website now performs as both a strong brand asset and a lead generation tool – reflecting the quality of their work and capturing demand across multiple boroughs in London.

Butternut Box

Butternut Box

+1,200% growth in Page 1 keyword rankings and 181% increase in organic traffic

Client Overview

Loved by dog owners across the UK, Butternut Box offers a subscription-based model built around personalised, nutritious meals. With a loyal customer base and a strong brand presence across other marketing channels, the business sought to grow organic performance to match the scale of its paid acquisition.

Challenge

Butternut Box approached Yellowball during a period of rapid expansion. With strong performance in paid channels and a loyal subscriber base, they wanted to scale their organic visibility and reduce reliance on paid acquisition.

We were brought on to work alongside their internal team and other agency partners to grow SEO as a major inbound channel – one capable of driving high-intent traffic, new subscribers, and long-term brand growth.

Key Results

+ 100 %

100%

+450% growth in total ranking keywords

  • +181% increase in organic traffic
  • Significant uplift in brand recognition and inbound conversions

Solution

Following an in-depth market and competitor analysis, we identified a clear opportunity to reposition Butternut Box’s search strategy. Our approach was built around three pillars: technical optimisation, strategic content creation, and authority-building outreach.

Technical SEO & Site Refinement

We began with a full technical audit to ensure the site was fully crawlable, indexable, and aligned with best practice. Quick wins were actioned across core site templates and metadata – providing a stable base for growth.

Content Strategy: New Acquisition & Retention

Our content strategy was designed to serve two purposes:

  • Attract new customers through high-intent, educational, and product-aligned search terms
  • Engage existing customers with value-driven content that deepened trust and supported retention

This dual-focus allowed us to expand the site’s topical relevance while supporting Butternut’s lifetime value goals. We also secured links from authoritative, industry-relevant publishers – boosting trust signals and domain authority.

Outcome

Over the course of two years, Butternut Box saw explosive organic growth. SEO now plays a key role in Butternut’s wider marketing mix, helping reduce CPA across the funnel while strengthening the brand’s visibility across key pet-related queries.

“Yellowball has been providing SEO services for me for around a year and I must say they are a great team who are always looking to work closer together and produce ever-increasing quality of work. Thanks for all your hard work!”

Blueberry Life
Blueberry Life

+7,700% increase in Top 10 keywords

Blueberry Life

+7,700% increase in Top 10 keywords and 326% rise in new organic users

Client Overview

Operating in the tech-for-good space, Blueberry Life combines advanced underwriting technology with a people-first approach to provide tailored life insurance solutions for individuals living with Type 2 diabetes. Their digital platform is designed to remove barriers and empower users with better coverage options – all underpinned by data, simplicity, and transparency.

Challenge

Blueberry Life came to Yellowball at a critical moment – having just launched a new website and looking to invest in SEO for the first time. Their goal was clear: attract qualified traffic from users actively searching for life insurance tailored to Type 2 diabetes.

The company’s Chief Growth Officer had worked with Yellowball in a previous role and brought us on board again – a testament to our impact and commitment to client success. With no existing organic presence and a highly specialised audience, the challenge was to build search visibility from the ground up while protecting the new site’s performance during migration.

Key Results

+ 100 %

100%

+3,458% increase in organic search click-throughs

  • +326% increase in new users via organic traffic
  • +7,700% increase in Top 10 ranking keywords

Solution

We began by auditing Blueberry Life’s newly launched website, mapping high-intent keywords to relevant transactional landing pages and ensuring these were fully optimised. A careful SEO migration ensured a smooth launch with minimal risk of ranking disruption.

Once the foundations were in place, we pivoted the strategy towards content – creating longform, high-authority guides centred on life insurance and Type 2 diabetes. These ‘pillar’ articles were designed to perform strongly in organic search while also providing a resource hub for Blueberry Life’s niche audience.

To amplify the impact, we implemented a structured internal linking strategy, funnelling authority from the pillar content into supporting blog posts focused on specific, semantically related topics. This cluster model helped grow keyword coverage and reinforced topical authority in Google’s eyes.

Regular technical audits ensured ongoing performance, removing any barriers to indexation or user experience. The results speak for themselves – Top 10 keyword rankings grew from just 1 to 78 in the first year, helping to establish Blueberry Life as a visible, trusted name in the diabetes life insurance space.

Outcome

Blueberry Life now enjoys a consistent stream of organic traffic from qualified users searching for tailored life insurance options. With strong visibility for non-branded search terms and a robust content ecosystem in place, the campaign continues to drive awareness, trust, and form submissions.

As we move into the second year of the campaign, we’re focused on scaling the content strategy, identifying new high-intent keywords, and securing long-term SEO performance in an increasingly competitive sector.

“The fact that Blueberry Life’s Chief Growth Officer brought Yellowball in after working with us at a previous business speaks volumes. This level of trust is exactly what we strive for – and we’re proud to be delivering measurable results for such an impactful brand.”

Applied

+5,200% increase in Page 1 keywords and 525% growth in conversions

Client Overview

Operating at the intersection of HR tech and social impact, Applied offers a radically fairer recruitment solution backed by behavioural science. With strong traction in both the UK and international markets, the platform is used by forward-thinking teams looking to increase diversity, reduce bias, and hire better – faster.

Challenge

Applied partnered with Yellowball at a pivotal stage – ready to scale both awareness and acquisition through organic search. With limited SEO visibility and relatively low domain authority, our challenge was to establish early search dominance around core themes, then expand outward to reach broader recruitment and HR audiences.

The ultimate goal: make SEO the highest-converting channel in their marketing mix.

Key Results

+ 100 %

100%

+1,336% increase in organic visibility

  • +1,249% increase in organic traffic
  • +525% increase in conversions via organic search

Solution

Strategic Topic Domination

We began with hyper-relevant, lower-volume search themes directly tied to Applied’s core USPs – blind hiring, anonymous recruitment, and unbiased hiring. Owning these terms early helped build authority quickly, paving the way to target broader, higher-volume recruitment and hiring terms.

This phased approach allowed us to expand reach while preserving relevance – leading to consistent growth in new users, search traffic and brand recognition.

Leveraging Thought Leadership

Applied’s team includes respected experts in DE&I, behavioural science, and recruitment innovation – a major asset for content credibility. We worked collaboratively to identify search opportunities where thought leadership could generate visibility and backlinks, securing featured snippets and citations across influential platforms.

Evolving Campaign Focus

As the partnership matured, our campaign adapted to business priorities – from deep technical SEO and buyer persona mapping, to scalable content production and authority-building outreach. Every initiative was designed to serve both top-of-funnel traffic and bottom-of-funnel lead generation.

A Fully Integrated Approach

This wasn’t a siloed SEO campaign – it was deeply embedded across Applied’s commercial, product and brand strategy. Close collaboration and shared ownership of goals meant every deliverable was mapped back to impact: traffic, visibility, and ultimately, conversions.

Outcome

Organic search has become Applied’s top-performing channel for conversions – consistently outperforming other acquisition routes.

With year-on-year improvements across traffic, rankings and demo/trial sign-ups, SEO is now a critical part of Applied’s growth engine. The campaign continues to scale as the business enters new markets and expands its customer base globally.

Their engaging, tailored training has attracted global brands including Trustpilot, LinkedIn, Amazon, and Microsoft.

Challenge

Flow State partnered with Yellowball to re-launch their brand with a new website, requiring a strategic SEO migration from their previous platform. The primary challenge was ensuring that their new digital presence reflected their unique, hands-on approach, while also optimising their key service pages for search visibility.

In addition, Flow State needed an ongoing content strategy to strengthen their authority in the sales training space and drive organic leads.

Key Results

  • 1,350% increase in non-branded organic impressions

  • Secured a global contract from an inbound MEDDIC training enquiry

Solution

Yellowball implemented a high-impact SEO strategy to enhance Flow State’s digital presence and attract targeted traffic to their core service pages. A key focus was optimising transactional pages to ensure they accurately reflected Flow State’s specialised training methodologies, such as MEDDIC and the Challenger Sale.

To drive sustainable growth, the team continuously monitored keyword performance, identifying quick-win opportunities while building long-term visibility for high-traffic search terms. Alongside this, Yellowball developed a robust content strategy, producing well-researched, high-quality blog articles that positioned Flow State as an authority in the sales training industry.

By adopting a dynamic, data-driven approach, Yellowball not only improved Flow State’s search visibility but also ensured that their website engaged the right audience – driving high-quality leads and measurable business growth.

Outcome

Through a structured SEO roadmap, Flow State has established a strong online presence that reflects their expertise and hands-on approach. Already a well-regarded name in the sales training industry, their enhanced search visibility is now expanding their reach – helping revenue teams worldwide unlock their full potential.

We’ve had a brilliant experience working with Owen, Laurie, Simon and the Yellowball team for both our website re-platforming as well as our SEO services. The team are highly-experienced, knowledgeable and reliable – and we valued their ability to guide us and challenge our thinking in key areas. Most crucially, they’ve delivered outstanding work which has already resulted in increased search visibility, enquiries and user experience.

Client Overview

PostScript is a family-owned online bookseller providing access to a large range of discounted books with up to 75% off publishers’ prices. PostScript have specialised in providing access to new or unusual titles and significantly reduced prices across a variety of categories.

Challenge

Organic search represented a significant opportunity for PostScript in a competitive environment where high street names and large industry players dominate. A primary challenge is the consideration of ever changing stock levels and seasonality, as well as maintaining the long standing relationship with existing clients whilst also reaching new customers. Additionally, a wide variety of categories and sub categories, coupled with thousands of SKUs required prioritisation and high levels of clarity on the campaign roadmap. 

Key Results

  • 555% ROI for the SEO Campaign

Solution

Throughout the campaign we have been systematically mapping out the search opportunity within major categories and sub-categories of books, subsequently coupling this data with existing and forecasted stock levels. This has then enabled us to take a holistic approach, pairing both sitewide optimisations as well as manual page by page optimisations to deliver great results. We have worked with Postscript heavily on structural elements of the site, identifying where new silos need to be built out to target new or upcoming opportunities within the market. 

Outcome

A clear campaign roadmap that takes into account the nature of an e-commerce platform that has ever changing titles and stock levels has allowed both PostScript and Yellowball to work in unison. Ultimately this has enabled us to maintain a commercial outlook on the campaign (and great ROI) whilst staying true to brand messaging throughout.

Santis Health
Santis Health

36.7% increase in new users

Santis Health is a world-leading prostate clinic in London, renowned for its ground-breaking robotic radical prostatectomies using the DaVinci robot. Led by pioneering robotic prostate surgeon, Dr Christopher Eden, whose expertise in laparoscopic and robotic techniques offers minimally invasive and precise treatments to patients.

Santis Health

36.7% increase in new users

Client Overview

Led by pioneering robotic prostate surgeon, Dr Christopher Eden, whose expertise in laparoscopic and robotic techniques offers minimally invasive and precise treatments to patients. Santis Health needed a website that reflected its clinical excellence, industry leadership, and patient-focused care to support people seeking prostate treatment.

Challenge

Santis Health’s original website focused on post-surgery care and did not reflect the reputation of Dr Christopher Eden as a leading provider of Da Vinci robotic surgery. The key challenges we ran into included limited SEO optimisation, despite regular authoritative blog posts by Dr Eden. The website was also missing out on broader patient searches from narrow keyword targeting and focusing on post-surgery blog posts rather than comprehensive prostate care. Finally, the website structure was targeting robotic surgery and not reflecting the full patient journey from screening to specialised surgery.

Key Results

+ 100 %

100%

36.7% increase in new users

  • number 1 ranking on Google for high-priority keywords

Solution

As part of a complete rebuild and design of the Santis Health website – which was also overseen by Yellowball – we implemented a funnel widening strategy to capture and enlighten people at multiple stages of the patient journey, transforming how Santis Health connects with them. We did this by creating a comprehensive prostate surgery hub page linking to specialised robotic surgery content. We developed a private prostate cancer screening page targeting early stage diagnostic searches and expanded keyword targeting from narrow terms like ‘robotic prostatectomy’, to broader terms like ‘prostate surgery’ and other general screening terms. 

Our blog content strategy transformed blog topics from surgery-specific articles to comprehensive patient education, covering topics such as prostate cancer prevention and symptoms. This expansion maintained the authoritative voice of Dr Eden while improving SEO optimisation, allowing the clinic website to serve men concerned about prostate health, along with those ready for surgical intervention.

Outcome

Our strategy reaffirms Santis Health’s position as clinical leaders. Our SEO efforts saw a 36.7% increase in new users. The clinic now ranks number 1 on Google for high-priority keywords, such as ‘cost of prostate surgery uk’ and ‘prostate cancer surgery cost’, showing the success of our approach.

Ongoing Partnership

Our work does not stop there. We continue to expand Santis Health’s digital reach, enhancing its connection with men seeking world-class prostate care and maintaining its position at the forefront of robotic prostate surgery innovation.

“I’ve been really delighted by Yellowball’s efficiency, expertise and communication since signing up with them 3 months ago to build a new website, SEO and PPC. They are clearly leaders in their field and I can highly recommend them.”

Stronghold Security Doors

55.4% increase in top 10 keywords

Stronghold Security Doors

55.4% increase in top 10 keywords

Client Overview

Stronghold Security Doors is a security door company and a leading provider of security doors in London and throughout the UK. While security doors are their main product and source of revenue, they also provide security windows and security garage doors. When they approached us, their website ranking was low, despite being an industry leader. We helped them through their digital transformation, matching their expertise with their online visibility to drive business growth.

Challenge

Stronghold Security Doors faced significant challenges that were affecting their online presence. Their website was purely HTML-based, requiring code-level changes, creating barriers to content development and site optimisation. Their low website ranking is affecting their ability to attract customers searching for security doors online. The combination of challenges posed issues, as it limited SEO opportunities and failed to showcase their expertise as security providers

Key Results

83.3% increase in quote requests through our intervention

  • boosted organic traffic on all pages by 44.3%

Solution

We oversaw the migration of their website from HTML-based to a CMS platform while ensuring that we minimise any initial traffic losses, laying the foundation for our SEO campaign. Our strategy focused on optimising priority product pages such as Security Doors and Security Garage Doors, where we implemented onsite optimisation targeting relevant keywords.

In addition to optimising the priority product pages, adding content to build the authority of the website regarding these products was a big part of their strategy. Most of the existing content was not ranking or generating traffic to the website. We began by removing or rewriting low-quality articles. We then started building up their blog section with strategically targeted content, such as security concerns and solutions, to improve the reach of the website as well as increase its authority.

Outcome

Our campaign was able to reverse their declining digital presence, transforming the negative trend to positive growth.  We achieved a 55.4% increase in Top 10 keywords and boosted organic traffic on all pages by 44.3%. Stronghold has benefited from an 83.3% increase in quote requests through our intervention

Ongoing Partnership

We aim to maintain Stronghold Security Doors’ position as London’s leading security door provider, while increasing its digital reach across the UK.

A great experience with Yellowball. We have now been working together for 10 months and results are clearly visible. Rudi and the team are also very professional in delivering content, plans for the months, quoters and having performance reviews unprompted. Easy, understandable reporting.

Radiocomms

95.7% increase in top 10 keyword ranking

Client Overview

Radiocoms Systems Limited is a communications company with 40 years of expertise, now established as the UK’s leading independent communications supplier. They specialise in the design, commissioning, deployment, and maintenance of wireless voice, video and data networks. With a substantial website displaying various products and services as well as a news and blogs section, Radiocom needed a strategic approach to transform its industry authority into organic traffic and conversions.

Challenge

Radiocoms’ large website with diverse products and services came with the challenge of properly optimising each page while focusing on their business objectives. Their products and services ranged from radio systems to apps and cameras, requiring us to prioritise to achieve meaningful results. We were tasked with managing SEO scope across the website, establishing clear priorities, improving technical performance and converting their expertise into digestible content to increase traffic and quote requests through organic traffic.

Key Results

8.6% increase in organic traffic as well as an increase in conversion rates

  • Top 10 ranking for a big portion of their target keywords

Solution

We started with a technical review to increase the speed of the website. We identified high priority pages with the highest business impact and implemented targeted onsite optimisation. The next step was to create a content strategy that demonstrated Radiocoms’ technical expertise to increase search visibility.

We developed high quality content on the priority pages to support the onsite optimisation carried out and targeted relevant keywords that demonstrated the success of their product, establishing their position as industry leaders. By focusing our blog creation on the selected product pages, we were able to focus on Radiocoms’ objective to increase the reach and authority.

Outcome

The campaign resulted in a 95.7% increase in Top 10 keyword ranking. We were also able to establish a consistent top 10 ranking for a big portion of their target keywords for priority product pages. The supporting content that we published also increased the reach and awareness of the Radiocoms brand. Radiocom has seen an 8.6% increase in organic traffic as well as an increase in conversion rates. The Radiocoms campaign is doing well with consistent increases across all KPIs monthly.

Ongoing Partnership

Our continued collaboration with Radiocoms ensures their top position while expanding their reach across the nation. We are constantly developing though provoking content to cement their authority and maintain their reputation.

Uvisan
Uvisan

82.4% increase in organic traffic in 6 months

Uvisan

82.4% increase in organic traffic in 6 months

Client Overview

Uvisan partnered with Yellowball to boost their digital presence as specialist manufacturers of UV-C disinfection solutions. Their products, which include UV-C disinfection cabinets and room decontamination systems, provide environmentally friendly, chemical-free sanitisation technologies for shared electronic equipment and environments. Emerging from the growing demand for infection control solutions during the COVID-19 pandemic, Uvisan needed to establish its authority in a niche yet competitive market.

Challenge

Uvisan faced a unique SEO challenge operating in a specialised market with low search volume keywords around their product. While their sector is growing, it has limited keyword opportunities as most searches are highly technical and specific. This challenge, however, created a great opportunity to educate about chemical-free disinfectants and their benefits.

Key Results

Solution

We conducted a comprehensive keyword research and identified relevant terms UV-C and disinfection cabinets. We approached this by optimising product pages for these keywords and creating educational content explaining the benefits of UV-C technologies and applications. We also developed sector landing pages, targeting VR labs, healthcare and educational institutions to maximise search opportunities.

Our content strategy focuses on addressing potential buyers’ pain points and questions through accessible articles. We focused on establishing Uvisan as thought leaders,  using FAQ’s about UV-C safety and effectiveness, creating detailed product specifications and sector-specific blogs targeting the benefits of UV disinfection.

Outcome

Our campaign delivered great results for Uvisan, with organic traffic increasing by 82.4% in 6 months. Uvisan also achieved top ranking for several priority keywords, including ‘UV-C disinfection cabinet’. Our SEO strategy continues to boost Uvisan’s visibility and amplifies its reach.

Ongoing Partnership

Our ongoing collaboration with Uvisan focuses on expanding its foothold in the industry as it grows. We continue to support Uvisan’s mission to establish UV-C disinfection as the preferred solution for chemical-free sanitisation across multiple sectors, positioning them for growth in this emerging industry.
