What is Search Evaluation?

In a digital world where a large percentage of all online traffic is driven by search engines, improving the relevancy of your search results can lead to major profits. Search evaluation is the human-powered evaluation of your search engine’s fetched results and the functionality of core elements such as auto-fill, auto-correct, result titles, result captions, related results, and more.

Improve your search relevance by using our expert analysts to evaluate your search engine. Train your algorithm with Lionbridge’s high-quality AI training data to provide your search engine with a solid ground truth.

Our Search Evaluation Services

Search Result Evaluation

Determine whether your algorithm is responding to search queries correctly by letting our team of experts test your search algorithm and rank the relevancy of your search engine results page.

Related Result Evaluation

Related results can keep users on your site longer and help with conversion. Don’t have exactly what the user is looking for? Use our crowd of experts to rate your search engine’s recommendations and related results to make sure they match the user’s query.

Caption Evaluation

Titles grab attention, but captions create interest. Evaluate your captions to make sure they are both relevant and engaging. Our multilingual and multicultural crowd of experts can handle caption evaluation for a variety of fields and topics.

Ad Review

Use our expert crowd to evaluate advertisement relevancy in regards to the user’s search query and intent. While advertisements are not a main function of search engines, they play a large role in the user experience of search and the professionalism of your site. Unrelated ads on your site will look like spam, whereas ads related to a user’s search query with professional copy will keep the search experience focused and maintain site credibility.

Search Query Categorization

Our team of experts can categorize the different types of queries relevant to your algorithm to ensure that your search engine accurately identifies intent and cultural context behind every query.

Query categorization is one of the most important elements of search relevance. If a user searches “android,” are they looking for information about android robots or the Android OS? When a term or phrase in a query is relevant to numerous subjects, cultural knowledge and intent become the deciding factors when fetching results.
