Google announced today that it is adding app activities from Google+ Sign-in to web search results.

“When users search for your app, they often want to go deeper and see what in-app content fellow users find interesting,” writes Google+ Director of Product Management, Seth Sternberg, in a blog post. “Today we’re making this possible by bringing app activity to Google search results.”

“Soon, if you search for a site or app on Google.com (and that app has integrated with Google+ Sign-In app activities), you’ll see popular and aggregate user activity to the right of search results,” explains Sternberg. “Searching for Fandango, for example, will show the top movies among Google users. And when you click on a movie, you’ll go directly to its page on Fandango.”

This is one of the biggest additions of Google+ into Google Search that we’ve seen since Google launched “Search Plus Your World” personalized search (not counting Google+ Local).

The feature is rolling out on desktop search over the coming weeks, and only with a limited number of apps at first. Launch partners include: Deezer, Fandango, Flixster, Slacker Radio, Songza, SoundCloud and TuneIn.

In somewhat related news, Google is shutting down the Meebo bar in favor of Google+ Sign-in.
