Helping users find mobile-friendly pages
Over the next few weeks google will be rolling out a change to the standard results pages for mobile. Now along with your list of ads and related links you will also be informed if the destination is mobile friendly (based on the inclusion of the meta viewport tag)
This can be a frustrating experience for our mobile searchers. Starting today, to make it easier for people to find the information that they’re looking for, we’re adding a “mobile-friendly” label to our mobile search results.
