Google's +1 button to add content recommendations

New feature will be present users with more content options when they hover over the button with their mouse, likely generating more page views.

Google is preparing a new +1 feature that will present users with other content recommendations when they hover over the +1 button with their mouse.

This could help deliver increased clicks for Web site as users will be presented with more content options similar to the content they just viewed. As an example, a visitor to Google's Chrome Web Store clicking the +1 on the Gmail app would see suggestions for apps like Offline Google Mail, Google Calendar, and Picasa:

"To keep these recommendations more relevant and on-topic, they will always refer to pages on the same domain or subdomain as the +1 button," Google Engineering Manager Julie Farago said in a company blog post describing the new feature.

The new feature, which is available for perusal on the Google+ Platform Preview, will be rolled out to Web sites in the next few weeks, the Web giant said today. Site admins who already use the button on their site won't have to do anything to get the new feature -- it will show up on these sites automatically.
