AS Google has announce that Google +1 button will be used to show the relevant content to users and it will ( or may be in) also added in the algorithm of Google search engine, So what is your strategy to get more +1 for your websites and inner pages.
I still have doubts using Google +1. Some SEOs also has doubts and theories about using +1 in their link building strategy. Some say that if you are logged on your google account and +1 your website, you can actually see an increase in SERPs by 1. For example, if your blog is number 8 in SERPs, if you +1 your site it will increase to number 7. That is if you are logged in or your friends are logged in. It also shares the same recommendation tool like FourSquare. If you visited a website and liking it by +1 it, when your friends do a search with a relevant keyword that site will appear in the top most recommended websites in SERPs and in the Ads section.
