Are you ready for the Google mobile-first index? That is a fair question that has been shaking the SEO world lately. Google has been talking about this change for the last few months and it seems that the update has been rolled out sooner than expected. Facts are since May 2015, mobile searches are more important than the desktop ones on Google. In this context, having more relevant mobile results has become an key objective for the search engine.
Moreover, John Mueller from Google has lately stated that a few sites were already being tested on the mobile-first index and that the only way to verify if you were impacted was to check your log files. In this article, we are going to discuss the whole concept, how you can monitor this transition and how to be prepared.
The mobile-first index aims at ranking websites regarding how Google has crawled the mobile version rather than the desktop version. This means Google will create and rank its search listings based on the mobile version of content, even for listings that are shown to desktop users and will use the desktop version only if the mobile version is not available.
As the number of searchers on mobile continues to grow and further surpass the number of desktop users, Google has decided to take action. Google realized that it makes more sense to favorise this large base of mobile users and provide them with the best possible search results and user experience in terms of content.
Until now, the mobile rankings were based on the desktop version of sites. In November 2016, Google was giving details about the mobile-first index but without communicating about an official release date.
The mobile-first index represents a major shift regarding the way Google discovers, evaluates and prioritize content.
On December 15th, John Mueller announced that Google had started testing some sites within its mobile-first index and showed how SEOs could identify if they have made the transition!
I think you would probably recognize it in the log files. If you see, if you look now probably something like 80% of the crawling is with the Googlebot desktop and maybe 20% is with mobile with the smartphone Googlebot.
And probably that will shift over and that most of the crawling will be done with the smartphone Googlebot and less crawling with the desktop Googlebot.
So if you like really watch out for your log files probably you can notice that fairly obviously. John Mueller
As just a few sites has made the transition to the Google’s mobile-first index, there is not that much documentation yet regarding how to monitor it. A few days ago, John Mueller officially advices to take a look at your log files to notice the transition. He also explains that on an average a site gets about 80% of the crawl from Googlebot desktop and approximately 20% is expected from Googlebot smartphone. If your site has been moved to the mobile-first index, the previous trend should reverse.

Google has shared a couple of recommendations regarding this new way to index websites. If you don’t have a mobile version of your website, there is no reason to worry. The search engine will instead crawl your desktop version.
If you only have a desktop site, we’ll continue to index your desktop site just fine, even if we’re using a mobile user agent to view your site, Doantam Phan, Product Manager at Google
On the other hand, if you own a mobile version, be sure contents and links are similar to your desktop version so that Google continues to rank your site as it did with your desktop version. Actually, if Google notices less content on a mobile page compare to the desktop version of this page, then it will probably just see the mobile version with less content.
If you need to optimize content organization on the mobile version, Gary Illyes from Google has stated that expandable content like tabs, boxes or accordions could be a valuable solution for user experience and won’t be regarded as having less content on a page.
In fact, a responsive approach seems to be the easiest way to keep the same amount of content on a page-by-page basis between desktop and mobile.
Overall, Google has not yet confirmed the real impact of mobile-first index on rankings but chances are it will come along the mobile-friendly update that fosters optimized results on mobile.
There are different points to focus on to get ready for the mobile-first index global release.
Compare your content between your mobile and desktop version. Be sure that the same qualitative, informative and user-friendly content is also available on your mobile version. Check your structured data as they are important for better indexing: it should be both on the mobile and desktop version of the site.
Verify if your mobile version uses dynamic serving or separate URLs from the desktop website. It can cause internal linking issues and user experience problems if it is harder for readers to find content when they are reading the site on mobile than they would have if they were viewing it on a desktop. For sites using separate mobile URLs, keep the existing link rel=canonical and link rel=alternate elements between these versions.
Page speed is an important ranking factor that have even more importance on mobile. In most cases, mobile and desktop versions don’t have the same performances regarding loading times. The point is not to have two exactly identical numbers but to have good performance on both version.
Be sure to optimize your crawl budget for mobile crawling. Log files can be used to manage issues potentially hurting your crawl budget such as orphan pages, 4xx errors, crawl errors or abnormal crawl activities.
