Situation
The Tester is a Netherlands-based health tech company that sells at-home self-testing kits for allergies, STIs, vitamin levels, and more. Through its online platform, users can easily and privately order tests, which are shipped to customers across multiple countries.
After a successful collaboration with Flowboost on Google Ads in the past, The Tester was looking for a native SEO specialist to improve the German version of its site.
Problem
After improving the Dutch version of their website and seeing good SEO results, The Tester wanted to achieve the same success in Germany, one of their main markets.
To make this happen, they needed a native SEO specialist who truly understood the German market. Having already worked successfully with Flowboost on Google Ads, The Tester decided to team up with the agency again to lead the SEO strategy for their German site.
Solution
To optimize The Tester’s website and boost its organic visibility, Flowboost implemented an SEO strategy based on the following actions:
SEO audit
Content optimizations focused on main categories and product detail pages
Technical improvements across the site
Blog content creation to get a better topical authority
After analyzing the results, it became clear that the biggest impact came from optimizing the content of the categories and product URLs, which significantly improved their visibility in search results.
German SEO focus
The Tester offers a wide range of at-home self-testing kits covering different health topics. During the analysis, Flowboost discovered that many of the German product pages lacked SEO-optimized content. This presented a strong opportunity to improve visibility and help each test page rank for relevant health-related keywords in the German market.
Result
As a result of the SEO optimizations, The Tester experienced strong organic growth across all key metrics.
Within five months, organic users increased by 12.5%, organic new users by 11.4%, and organic sessions followed the same upward trend. Visibility also improved, with 30.8% more keywords ranking and a 168.4% increase in SERP features in Germany.
The website now performs much better in search, attracting more qualified traffic and improves The Tester’s position in one of its most important markets.
