With the explosion of mobile navigation (that is: we are approaching 50% worldwide and on average 25% in France), it was to be expected: Google officially announced, in early November, the launch of a new mobile first index system for mobile. Where the change is consequent is that the smartphone version will become … the reference! Indeed, so far, it is the computer version that was the basis of Google’s algorithm. But it was time for the standard to change and adapt to the changing behavior of Internet users. Now that the trend of mobile is anchored in time.
Note that in the information provided by our referent search engine (no offense to Bing and Yahoo), we must remember the term “mobile” refers to “smartphone” and that tablets are related to computers.
If the mobile version of your website has been made responsive design or via dynamic serving. You have already done a good job of SEO and you have structured your data, nothing will change. Indeed, even if the analysis will be done first on the mobile site if the content of the latter (URL included) is identical, there is no reason that the result differs.
As a matter of conscience, do some checks from the mobile optimization test (made available to everyone by Google). This will do an analysis of your URL and will check that the tested pages are well adapted to mobile. Do not forget, also, to make sure that access to resources (CSS, JS, graphic content …) is not blocked to mobile robots.
On the other hand, if your URL changes (for example www.monjournalfavori.com and m.monjournalfavori.com), you will have to check that the contents of the mobile version remain as rich and optimized. This will seem obvious to you by reading it, but if some keywords or phrases, essential to your SEO SEO so far, appear only on the desktop version, the need for your Google traffic may drop, if you do not see your content stand out on the desired queries.
If your site is not compatible with smartphone navigation (while we were talking about the importance of having a Mobile friendly site here), without taking into account the doors you are closing given the current trend in term navigation is always the desktop version that will be analyzed, but your SEO will take a shot. This is obviously inevitable since you will pass behind the mobile sites better adapted and referenced than you.
First of all, if you do not have a mobile version. Or it is not optimized: this is the time to never get started. This new Mobile First index will be the new standard in a few months. So it’s better to take the lead rather than be surprised by the time and react too late … once your work to please the SERP will be largely lost.
After, make all the necessary controls, by consulting the tools that Google has moreover put at your disposal. The Search Console ( https://www.google.com/webmasters/tools/home?hl=fr ) and the Test mobile optimization ( http://www.google.com/webmasters/tools/mobile-friendly/?hl=en ). This will give you tracks to explore and rework.
But rest assured, everything will not change either: if your ” canonicals ” tags have been made. That your structured data are relevant and present in both versions of your site. And that the navigation on your website is nice and fluid on a smartphone. You will probably not see any difference in your traffic.
Google has not suddenly decided to reverse the order of things, nor the order of results of its search pages! Simply, it was predictable and obvious that a mobile optimization was going to prevail at all. To answer the needs of the Net surfers, who do more and more their research since their telephone. And it is to this evolution that the Index Mobile First responds.
