Google is on track for mobile search queries to overtake those on desktop this year, and on Tuesday it took one more step forward in how it is will control that experience on behalf of its users — for better or for worse. The company has announced that it will now flag to its users when websites listed in their search results may have elements that will not show up on a users’ device. That unsupported code typically results in missing elements and blank screens. To be clear, Google does not say that it will leave out those sites altogether in its search results, or bar you in any way from visiting them. But I suspect a lot of sites that are written with un-supportable code (even in part) will see a drop in their traffic as a result of those warnings.
