We’ve reported not too long ago on the fact that Google was testing out a new feature in a special Google+ Group. Today Google is rolling out this feature to everyone. This feature changes the +1 button to become a recommendation button.
Until now the button was mainly used for acknowledging a page is to your liking and you could share through it as well. Now Google is adding recommendations.
The recommendations will be from the site you are visiting and will mean another boost for the usage of the +1 button without a doubt, because it suddenly became interesting for website owners to persuade you to click the +1 button, because it will show you more from that specific site.
