Google recently released it's new +1 button. It's a little like a simplified "like" button where you can recommend webpages to your friends when logged in to your Google account.
The button will appear on Google search results, adwords listings and on your website if you choose.
Visitors who are not logged in to their Google account may still see the +1 button results, but not be able to use it for recommendation.
What does +1 mean for you?
Google has stated that the +1 will also be used in their search ranking algorithms, so you now have an on-page tool where your happy visitors can directly impact rankings positively on the Google search engine. With Google trending more and more toward social media in their listings and algorithms, the +1 button is their next notable step to filtering out link farm usage. With less ranking manipulation, your popular site has a better opportunity to rank where it's meant to. Similar to the "like" button, the +1 button only registers when the clicker is logged in to their Google account, thus reducing the likelyhood of spamming.
