What this service is designed to deliver when deployed inside your workflow.
Search Relevance Outsourcing for UK Companies.
Human evaluators judging search result quality, ranking relevance, and query intent for your search and recommendation systems. Nairobi-based teams from £7,200 per evaluator per year.

Overview
What is Search Relevance?
Search relevance outsourcing involves deploying trained human evaluators to judge the quality, accuracy, and usefulness of search results, recommendation outputs, and information retrieval systems. Treba provides dedicated search quality teams in Nairobi who rate result relevance, assess query-intent matching, and provide the ground truth data that improves your search algorithms.
Typical client
UK SaaS platforms with internal search features, e-commerce companies optimising product search, marketplace businesses tuning recommendation engines, and AI companies building retrieval-augmented generation (RAG) systems

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.
