Google is undertaking a new effort to better identify content that is potentially upsetting or offensive to searchers. It hopes this will prevent such content from crowding out factual, accurate and trustworthy information in the top search results.
The effort revolves around Google’s quality raters, over 10,000 contractors that Google uses worldwide to evaluate search results. These raters are given actual searches to conduct, drawn from real searches that Google sees. They then rate pages that appear in the top results as to how good those seem as answers.
Quality raters do not have the power to alter Google’s results directly. A rater marking a particular result as low quality will not cause that page to plunge in rankings. Instead, the data produced by quality raters is used to improve Google’s search algorithms generally. In time, that data might have an impact on low-quality pages that are spotted by raters, as well as on others that weren’t reviewed.
