Google Announces That the Roll-out of Mobile-first Indexing Has Begun
Google announced that it has started the process of rolling out mobile-first to a large volume of sites that “follow the best practices for mobile-first indexing.” Google will be sending messages via the Google Search Console to notify webmasters that their sites have been migrated to mobile-first indexing. (See screen capture below) Google states that site owners who have been moved over will see significantly increased crawl rates from the Smartphone Googlebot. Additionally, Google will show the mobile version of pages in Search results and Google cached pages.
What to Do If Your Site Has Not Moved Over to Mobile-first Indexing
Google states that “sites that are not in this initial wave don’t need to panic. Mobile-first indexing is about how we gather content, not about how content is ranked. Content gathered by mobile-first indexing has no ranking advantage over mobile content that’s not yet gathered this way.” However, Google does continue to encourage website owners to make their content mobile-friendly. “We do evaluate all content in our index -- whether it is desktop or mobile -- to determine how mobile-friendly it is.”
Recap on What is Mobile-first Indexing?
To recap, Google’s crawling, indexing, and ranking systems have typically used the desktop version of a page's content, which may cause issues for mobile searchers when that version is vastly different from the mobile version. Mobile-first means that Google will use the mobile version of the page for indexing and ranking, to better help – primarily mobile – users find what they're looking for.
