Google Plus One (+1) Is nothing but Facebook “Like” Button for Great Google Search.
Google defines Plus One as a “public stamp of approval,” and it is exactly that. When you like to share a Search Result with friends just click +1 Button on result link , your name becomes associated with that link and it will showup to your friends “in search, on ads, and across the web,” .It also shows up in a feed on your Google Profile, which is required to use the product.
Google +1 is a Plus for a number of social features that Google introduced in search earlier this year, such as the ability to see which friends have tweeted a given link in search results.
Now you can search more faster & get the results you wanted because you get the right recommendations (because they come from people who matter to you), at the right time (when you are actually looking for information about that topic) and in the right format (your search results).
Soon Google will also launch Google +1 Button for Website & Blogs. Below are some screenshots of Google +1 (my own) :
&So you want to try it before it rolling to your main Google Account. Follow these steps :
1) Log-in to your Google Account (you always need to be if you want to share).
2) Create Google Profile (if you havent) . If you have created already then upgrade it to new profiles.
3) Go to : http://www.google.com/experimental and click Join this experiment button next to +1 Button. You are done now. You can share your results with friends. :)
