For a glance into just 6 of the metrics, we evaluated these top 10 UK home blood and allergy testing kit suppliers, check out our quick-look table below:
The 70+ pages of research benchmarks each retailer based on 50+ metrics and indicators of successful digital strategy, including organic visibility, domain authority, paid media ads, conversion performance, technical performance, site speed, universal search, content, social ads, accessibility, and mobile performance.
Some of the leading players in the space are high spenders on paid media channels such as Google, Bing and Facebook - but have a poor or sub-optimal conversion improvement strategy. Without an optimised, sophisticated conversion strategy that maximises the conversion rate, the return on investment is unsustainable or will underperform. Scaling spend on paid media is not achievable unless the conversion rate delivers optimal performance in the sector. Some in the space have paid media spend levels from £30k+ per month but dedicate minimal resources and budgets to conversion testing. Given the cost per clicks on ad networks will continue to rise, we recommend spending at least 10% of your paid media budget on ongoing conversion optimisation testing schedules to ensure your paid media ROI maintains long-term viability, competitive advantage, and sustainability.
Pay-Per-Click marketing is constantly evolving, with more and more advertisers being forced to hand over a lot of control to Google's algorithms as the push for automation grows ever stronger. There are still key elements of control that we have though, the main one of these being budget which is ultimately something the algorithms can't take from you. That's why being smart with your budget and ad coverage is essential to achieving strong results and bettering what your competitors have to offer.
For Q4 2025, the average monthly budget wastage across these UK home blood & allergy testing suppliers was £1,893, with some of the top players in the market spending a considerable amount on areas and audiences unlikely to deliver a return. We can see this in more detail when looking at the average monthly cost per cost-per-click (CPC) amongst advertisers, with the average of this metric being £23 . This highlights how competitive the market is and how important it is to control your budgets effectively.
There are varying monthly ad budgets across the competitors in the report. While this gap highlights the competitive advantage that larger budgets can provide, it's not just about spending more; it’s about spending smarter. By focusing on driving efficiency in campaign management, targeting, and budget allocation, businesses with smaller budgets can still effectively compete with larger players. Investing in data-driven strategies and refining ad performance can help close the gap and maximise the return on every pound spent, enabling growth even in a competitive landscape. Relative to their spend, Lifelab Testing reported the lowest monthly cost-per-click (CPC) at £4, and Forth has the highest at £81.
The report highlights the importance of budget efficiency by comparing monthly ad spend with estimated CPC in relation to your competitors, see who has the highest and lowest CPC. To maximise the effectiveness of your budget, it’s essential to focus on driving CPC down while maintaining or improving campaign performance. In this report, Forth has the lowest estimate monthly ad spend at £1,290, and Medichecks has the highest at £53,500.
By optimising targeting, refining ad copy, and leveraging data to identify high-converting opportunities, you can ensure every click delivers maximum value. This approach not only stretches your budget further but also boosts your return on ad spend (ROAS), enabling you to achieve stronger results without simply increasing expenditure.
Savvy digital marketers know that having a technically sound website is an essential component of a successful fully integrated digital strategy - plus a site capable of maximising conversion performance. All UK home blood and allergy testing kit suppliers should aim to reduce their 4xx errors to prevent search engines from believing the website isn’t maintained.
In our previous audit, Everly Health reported the most 404 errors (353). This quarter, Everly Health has dramatically reduced their 404 errors to just 1, showing they’re regularly monitoring their site. Currently, the supply to watch is YorkTest Laboratories, with a total of 324 404 errors. Monitoring 404s can uncover deeper technical or structural issues within a website. Regular checks might reveal outdated URLs, incorrect redirects, or missing resources that affect site performance. Fixing these errors ensures that both internal and external links work properly, preserving the site’s functionality.
When 62% of consumers are less likely to convert if they have a negative mobile site experience, ensuring that your site is quick and easy to load will see a significant improvement on your overall conversion rates. Brands should aim to make their website as fast loading as possible — ideally, a maximum of 3 seconds for a page load — to prevent users from becoming impatient.
This quarter, the mobile site speed ranged between 50 and 25, with Everly Health reporting the slowest speed (below the recommended minimum 50%). Search engines also prioritise mobile speed when ranking websites. Google’s mobile-first indexing means a sluggish mobile site can negatively affect overall visibility. Optimising for speed ensures that your site remains competitive in search results and reaches a wider audience.
Domain authority (DA) is an essential metric for measuring the effectiveness of SEO performance and helps create a reliable overall gauge of how effective your site is at achieving organic traffic, i.e. ‘free’ traffic that isn’t gained through sponsored ads. All home blood and allergy testing kit suppliers will want to receive quality backlinks from a variety of domains to help improve their DA score.
A ‘good’ DA really comes down to how your competitors are performing, however it is generally considered average between 40 and 50, good between 50 and 60, and excellent above 60. In our last report, Test My Allergy received the lowest DA score (19). This quarter, Test My Allergy remains the supplier to watch, and they’ve since decreased their DA score to 14. Maintaining a strong domain authority score supports long-term digital growth. It shows consistency in quality, reliability, and engagement. As a website’s score improves, their site becomes more resilient to algorithm changes and better positioned to outperform competitors.
A strong organic performance is strategically important as it ensures your site ranks above competitors for core, transactional keywords. When 93% of your customers won’t go past the first page of Google, your absence or lack of targeting for essential keywords will cost you conversions. Suppliers can increase their organic traffic by following a keyword strategy and ensuring their website is user-friendly to encourage returning visitors.
Four brands reported a drop in organic traffic on desktop, with LetsGetChecked receiving the biggest loss (-60%). On mobile, 2 brands reported a drop in organic traffic, with LetsGetChecked receiving the biggest loss on this device, too (66%). Balancing organic traffic across devices also strengthens long-term SEO stability. Search engines reward sites that perform well everywhere, not just on one platform. By maintaining mobile-friendly designs and desktop usability, websites secure consistent growth and visibility.
Google Universal Search Results are an evolving opportunity to make your pages visible on a SERP (Search Engine Results Page). Universal results often appear before traditional listings and are eye-catching for users. Universal search results refer to rankings on a SERP that are not the traditional ‘blue line’ Google link, and a retailer can appear for universal search results without being strong in standard rankings. 'Reviews' and 'images' are both great options for home blood and allergy testing kit suppliers, enabling them to give users a good perception of their service and products directly from the SERP.
Everly Well remains the brand to beat for the most Universal Search appearances (3,448) — a decrease from 3,847 in our previous audit. The majority of this brand’s appearances came from ‘images’ (1,900).
Longtail keywords are often considered high intent and potentially more likely to convert as a searcher is being more specific. Optimising for longtail keywords also puts your content strategy in a strong position to rank for new search terms as they enter Google’s index. Home blood and allergy testing kit suppliers will use longtail keyphrases, such as ‘home health test kit’ and ‘blood test and health check’ to actively work on increasing their organic traffic.
Randox Health continues to secure the most longtail keyword appearances for position 3 (813) — putting Medichecks in second place this quarter. However, Medichecks secured the most appearances for positions 4–10 (2,414) — an increase from 2,070 previously. Longtail keyword use supports voice search optimisation. As more users search conversationally on mobile or with smart devices, natural phrases become essential. Adapting content for these detailed queries keeps websites ahead of evolving search trends.
With the number of Facebook users in the United Kingdom (UK) hitting over 44 million users in 2023, it is not surprising that companies have jumped at the opportunity to advertise on the social media platform. Facebook’s UK digital advertising revenue has been estimated to have breached 2.6b GB pounds in 2019. Facebook ads are an opportunity for home blood and allergy testing kit suppliers to expand their audience reach.
We’ve included screenshots of Randox Health’s sponsored Facebook posts. This UK home blood & allergy testing supplier should reduce the amount of text per post to make their content easier to scan.
When it comes to social media and on-site content strategies, it is important to release content that has a longer shelf life. An article is considered 'evergreen' if it has maintained its relevancy to an audience for a long period of time. It's great for your engagement, but great for Google, too, who will recognise content that achieves traffic over a long period.
Everly Health secured the most Facebook Likes (107,500) and the most Instagram followers (187,200). Facebook was the most popular social media platforms of all brands. Everly Health received the highest total engagement rate (6,085) and the highest average engagement (289).
About 20% of people in the UK have a disability – 2 million of which are people living with sight loss. In addition, 1 in 12 men and 1 in 200 women have some degree of colour vision deficiency. Home blood and allergy testing kit suppliers should aim to reduce accessibility alerts and contrast errors to improve readability for those using a screen reader and for anyone with a colour vision deficiency.
In our previous audit, Lifelab Testing reported the most accessibility alerts (123). This quarter, Lifelab Testing remains the brand to watch, and they’ve since increased their accessibility alerts to 125. Accessibility fixes often lead to better usability for all visitors. High contrast and well-structured design improve readability, navigation, and overall user satisfaction. By addressing alerts early, websites deliver a smoother and more enjoyable experience for everyone.
