More than half of Google’s search results now come from its mobile-first index

This month, Google announced that more than half of all web pages in its search results around the globe are being pulled from its mobile-first index.

That means that the majority of pages being shown in Google’s search results were crawled, indexed, and ranked based on the mobile version of that page. As such, it marks a huge turning point for the increasing mobile-emphasis in web design and optimization.

What exactly is mobile-first indexing?

Over the past two years, Google has established a second, distinct index which prioritizes mobile pages and search results. This came as more than half of all search results were originating from mobile devices, rather than desktop computers.

Gradually, Google has expanded this index with the intent of eventually making it the primary search index.

With the launch of this index, Google also changed how it approached website indexing. Rather than defaulting to the desktop version of a page to assess its optimization and search value, the search engine began indexing mobile pages over their desktop counterpart. Thus, Google began its process of “mobile-first indexing.”

Is your site in Google’s mobile index?

If your site has been added to Google’s mobile-first index, you will likely have been notified within Google Search Console. Simply check your messages to see if your site has been migrated over.

If your site has not been migrated over, there is a chance that Google is having issues viewing the mobile version of your site, has found significant discrepancies between the mobile and desktop versions of your site, or has decided your mobile version is not up to snuff.

You should probably take the time to review the mobile version of your site to ensure it is properly optimized and laid out for Google’s search crawlers. You should also ensure that both versions of your site are largely similar, as Google prefers websites with parity across devices.
