How our Quality Raters make Search results better

At Google, we’re always working on ways we can improve your Search experience.

We constantly experiment with ideas to improve the results you see. One of the ways we evaluate those experiments is by getting feedback from third-party Search Quality Raters. Quality Raters are spread out all over the world and are highly trained using our extensive guidelines. Their feedback helps us understand which changes make Search more useful.

Raters also help us categorize information to improve our systems. For example, we might ask what language a page is written in or what’s important on a page.

We use responses from Raters to evaluate changes, but they don’t directly impact how our search results are ranked.
