Yesterday (as I covered at SEL), Gary Illyes from Google said at PubCon that Google will be rolling in more web sites into the mobile first index starting over the next several weeks. Google first began moving some sites into the mobile first index last October but said it was a very limited number of sites that were in that batch.
Google promised, if your site is not ready it won't be moved yet. Well, now the next batch is coming and eventually your site might be next. So make sure to read the Google tips and my post on what you need to know as well as keep an eye on your log files and changes.
Because in the next month or two, more sites might be moved to this mobile first index and it might be one of your sites!
Here are those tweets:
