While Google+ is facing a lot of heat for failing to attract a critical mass of users, some say the social network has a secondary goal that it may be succeeding at – helping inform its search results. One of the key ways it is doing that is by unifying the “+1” feature and releasing it to anyone who wants to use it. It’s easy for any site operators to install the +1 button so that users can like their content and easily share it to friends.
Today, Google+ announced on their developer blog that they’re going to improve this service. When websites install the +1 button on their blog, they’ll be able to activate a “recommendations” feature. When users hover over the +1 button, other recommended items will pop up that the user can +1. This helps the virality of a domain’s content as well as the social interactivity.
I feel that Google is slowly rolling out these sorts of features and collecting data so that they are able to eventually provide a great social search. I think many users are looking for a place where they can search for something like “car reviews” and see which of their friends have entered reviews, +1/liked certain reviews and see what sites have the most +1/likes overall.
