Google +1 Button for Websites
A week ago, Google launched the +1 button for websites that can be placed anywhere on your web pages via a short code snippet. Use the +1 button to publicly show what you like and recommend content to your friends and contacts, and make search results even more helpful and relevant.
The +1 button came up in a variety of sizes and has multi-language support. If you want to add the Google +1 button to your website, check the code generator page and customize the button as you like.
I already embed the +1 button in my post pages. You should do that too.
And here’s a video for you to learn more about the +1 button.
