Google has been working on mobile-first indexing

[rochon.a1.119]

some time, and has developed a response to the dramatic shift in how people search and navigate the web, and the widespread adoption of mobile devices in almost every part of our lives.

We can say that we now live and work in a world totally focused on the mobile-first approach (mobile devices first).

The first announcement that Google was moving away from algorithms that typically focused on desktop-first versus mobile-first came in 2016 .

At the time, Google said:

Today, most people search on Google using a mobile device. However, our ranking systems typically look at the desktop version of a page's content to assess relevance to the user. This can cause problems when the mobile page has less content than the desktop page because our algorithms aren't evaluating the actual page that a mobile user sees.

But between 2016 and today, we've seen an almost complete shift lebanon mobile database by Google toward mobile-first indexing .

By March 2021 , Google will have switched ALL websites from desktop to mobile indexing, having gone through a transition period since their systems recognized they were ready to do so.

Every new website launched after July 2019 was automatically indexed for mobile-first, although some sites have not yet made the move.

And while many of you have been dealing with mobile Googlebot crawling for some time, it's something that every SEO and marketing professional needs to pay close attention to.

In the next few months, Google will be 100% mobile-first, which means you need to make sure you understand what that means and how to optimize for this approach.
