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.

Google has already begun rolling out its mobile-first index to some users, but there are still a lot of questions about how exactly the search engine’s new separate index actually functions.

One such question got a surprising answer yesterday during the Google State of Search conference, as Maile Ohye told the audience that Google won’t index the AMP version of your page in the mobile search index – even when you don’t have a mobile-friendly alternative.

Google’s Gary Illyes also confirmed the news on Twitter after the conference:

That means if you’ve been using AMP pages as an alternative to making your website mobile-friendly, the search engine will skip over indexing your AMP pages in the mobile-friendly search index. Instead, it will by default choose to index the desktop version within its older index.

There is a way to force Google to index your AMP pages in this situation using a rel alternate attribute, but otherwise Google’s index will default to your desktop versions of pages.

This is particularly surprising because Google has pushed AMP as the ultimate way to deliver content to mobile users quickly and without losing ad revenue. But, in this case it seems the streamlined design of AMP pages leaves something to be desired. It may be the lack of site navigation options is what made Google decide to favor desktop over AMP in their index.

This change will most likely only affect a very small number of websites, but it is an odd choice for the search engine. The vast majority of websites who have adopted AMP also maintain a mobile version of their site.

As announced last month, Google is officially making its first step towards the launch of mobile-first indexing with the test of its mobile-first search index.

The company confirmed the testing has officially started via its company blog:

“Although our search index will continue to be a single index of websites and apps, our algorithms will eventually primarily use the mobile version of a site’s content to rank pages from that site, to understand structured data, and to show snippets from those pages in our results. Of course, while our index will be built from mobile documents, we’re going to continue to build a great search experience for all users, whether they come from mobile or desktop devices.”

This means in the future Google will increasingly prioritize crawling the mobile versions of a site’s content, rather than treating desktop as the “main” version of your site.

The company also gave some quick tips to help you make the most of this change as it is happening:

  • If you have a responsive site with identical content across mobile and desktop, you shouldn’t have to change anything.
  • If you have a site where the primary content and markup is not identical across mobile and desktop, you should consider making some changes to your site.
  • Make sure to serve structured markup for both the desktop and mobile version.
  • Google recommends using the Structured Data Testing Tool to verify the equivalence of structured markup across desktop and mobile by typing the URLs of both versions into the Structured Data Testing Tool and comparing the output.
  • When adding structured data to a mobile site, avoid adding large amounts of markup that isn’t relevant to the specific information content of each document.
  • Use the robots.txt testing tool to verify that your mobile version is accessible to Googlebot.
  • Sites do not have to make changes to their canonical links.
  • If you are a site owner who has only verified their desktop site in Search Console, please add and verify your mobile version.
  • If you only have a desktop site, Google will continue to index your desktop site just fine.
  • If you are building a mobile version of your site, do not launch it until it’s ready. Google says: “a functional desktop-oriented site can be better than a broken or incomplete mobile version of the site.”
