The challenge

Why UK companies struggle with search relevance.

Your search bar is the most used feature on your platform, but nobody is systematically measuring whether it returns good results. Automated relevance metrics — click-through rate, dwell time — measure user behaviour, not result quality. A user clicking the third result does not mean the first two were irrelevant — they might have had better titles. Without human evaluation, you are optimising for engagement proxies instead of actual relevance. UK-based search quality evaluators cost £28,000+ per year, and the work requires sustained attention to repetitive tasks that are hard to recruit for domestically.
