we noted earlier this year, today's the day we begin globally rolling out our mobile-friendly update. We're boosting the ranking of mobile-friendly pages on mobile search results. Now searchers can more easily find high-quality and relevant results where text is readable without tapping or zooming, tap targets are spaced appropriately, and the page avoids unplayable content or horizontal scrolling.
April 21st's mobile-friendly update boosts mobile search rankings for pages that are legible and usable on mobile devices.
Affects only search rankings on mobile devices
Affects search results in all languages globally
Applies to individual pages, not entire websites
While the mobile-friendly change is important, we still use a variety of signals to rank search results. The intent of the search query is still a very strong signal -- so even if a page with high quality content is not mobile-friendly, it could still rank high if it has great content for the query.
