Google started a new tool Google +1 Button. I wants the information how this new tool help is website promotion. I not know how we can use it. Can some one explain the use of +1 Button .
if you click +1 you basicly say that like the content you are looking at... so google will know that they have done a good job in providing the correct search results for you.
If you like the results you can click +1 button as your vote. The result which gets more votes will be displayed at top of SERP. Watch this video for more information. http://www.google.com/+1/button/
This button is like Google's own social network that asks for recommendations from your friends and contact list.... just like Facebook's LIKE button. This button is for your users.. they will use it to recommend your site to the people in his network. I suppose webmaster have no control over this button, but yes it can helps you in maintaining a good reputation. More recommendations will help google rank the websites better. Get ready to entice your users to click +1 button your website. Well, the tool is still in its testing phase.... Google will notify you whenever it ready for implementation.
