Google is rolling out “mobile first indexing” officially. After a year and half of testing and experiment, Google has started migrating websites that follow the best practice for mobile-first indexing.
In 2016, Google started the experiment to make their mobile first indexing. This rollout is only for sites that “follow the best practices for mobile first indexing,” Google said.
Mobile-first indexing means Google will use the mobile version of a web page “for indexing and ranking, to better help our – primarily mobile – users find what they’re looking for,” the company writes in a blog post.
However, Google will continue to have one index which they use to serve search results. They do not have a “mobile first index” that’s distinct from their main index. Previously, they use to index desktop version, now they will be using the mobile version of content.
As we know, Google has started prioritizing mobile website in different ways. It started to boost the rank of the mobile-friendly webpage on mobile search.
Google has started sending a notification to the webmasters via search console, about the migrating to mobile-first indexing. The webmaster will notice higher crawl rate from Smartphone Googlebot. Additionally, Google will show the mobile version of pages in Search results and Google cached pages.
Also, this is just the first wave. 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 or desktop content. Moreover, if you only have desktop content, you will continue to be represented in their index.
