First currently available for users in the Platform Preview, before going live to all users
Google said it has added the +1 button to its sites all over the web with popular and related content recommendations from friends.
Once the user floats over the +1 button on a website, it will show the list of recommended site options and apps even if ther user has signed in or not.
The new feature could result in increased page views and engage users as they will be able to take advantage of more content relevant to the content that was just viewed on their site.
When users go the the Chrome Web Store and look at +1 recommendations on the Gmail app, they can see related apps like like Offline Google Mail, Google Calendar and Picasa and recommendations from friends.
Recommendations will always refer to pages on the same domain or subdomain as the +1 button, to make them more relevant and on-topic, Google says.
Google engineering manager Julie Farago said, "If you’ve already added the +1 button to your site, there’s nothing more you need to do. Recommendations will work across all +1 buttons for all users, whether or not they’re signed into Google+."
Users can sign up for a developer preview to see recommendations before the feature is launched to the general public in the coming weeks after testing.
Google said its +1 button connects Google+ to the rest of the web by making it easy for users to start a conversation with their circles while also providing timely recommendations to their friends and contacts.
Recommendations from friends are a trusted source of advice and +1 annotations help people see these recommendations as they use Google services, potentially bringing visitors’ more informed traffic.
