Google announced that if you conduct a Google search on your iOS or Android device and a site that comes up is built in Flash technology, they will warn the searcher not to click to the site because it would be a bad user experience.

The note reads:

Google said this is launching today, and the notice will show when their algorithms detect pages that may not work on their devices. For example, Adobe Flash is not supported on iOS devices or on Android versions 4.1 and higher, and a page whose contents are mostly Flash may be noted.

Google’s Pierre Far said on Google+:

Time to upgrade folks.

Google recently began showing faulty redirect notifications in the mobile search results as well.
