Google’s Mobile-Friendly Algorithm Will Roll Out April 21
(1) The algorithm will take a few days to a week to completely and globally.
(2) You are either mobile-friendly or not, there are no degrees of mobile-friendliness in this algorithm.
(3) The fastest way to see if your web pages are mobile-friendly is to see if you have the mobile-friendly label in the live mobile search results now.
From a Google spokesperson:
We are expecting it (the mobile friendly algorithm) to roll out on April 21st, we don’t have a set time period because it is going to take a couple of days to roll out. Maybe even a week or so.
As we mentioned in this particular change, you either have a mobile friendly page or not. It is based on the criteria we mentioned earlier, which are small font sizes, your tap targets/links to your buttons are too close together, readable content and your viewpoint. So if you have all of those and your site is mobile friendly then you benefit from the ranking change.
But as we mentioned earlier, there are over 200 different factors that determine ranking so we can’t just give you a yes or no answer with this. It depends on all the other attributes of your site, weather it is providing a great user experience or not. That is the same with desktop search, not isolated with mobile search.
How do you know if your web pages will be mobile-friendly or not? There are a few ways, but Google said the easiest way is to see if your current pages have the mobile-friendly label in the live mobile search results now.
Take out your phone, look up your web site. See if there is a gray mobile friendly label in your description snippet. If it is in the search results, if you see it, that means that Google understands that your site is mobile friendly and if you don’t see it then we don’t see that your site is mobile friendly or your is not mobile friendly.
If your site is not “mobile-friendly” as of April 21 you will be dropping to the bottom of search results on Google. That’s not good! Mobile-friendly is no longer an option, it is a requirement.
