Does Accessible Search Filter Out Inaccessible Content?
No. First of all accessible is a very subjective measure — what’s more, queries can vary widely with respect to how accessible the results are. As an example, if you are looking for information such as weather forecasts or reference material such as the definition of an unfamiliar term, the result set often consists of both accessible and inaccessible content. In these cases, Google Accessible Search promotes those results that have been measured to be more accessible. On the other hand, if the particular query is about video games, the chances are fairly high that a majority of the best results for that query will be visually busy pages. So in the final analysis, we never filter content in Google Accessible Search; we pick the best results exactly as we do with regular Google search, and then re-order the top results by their level of accessibility.
