“+1” is often used as a digital shorthand for “this is pretty cool.” It’s also a way for friends, contacts, and the rest of the world to find great things on Google search. Google launched the +1 button back in March as a way to help share web content and make search more personal and relevant.
To add the +1 button to your blog, you’ll need to enable Share buttons on Blogger. To do this, go to Design | Page Elements on your Blogger dashboard, find the Blog posts area, click on Edit, and select the “Show Share Buttons” option. If you are already using Share buttons, the +1 button will automatically show up as a new share option.
By adding the +1 button to your blog, you’re providing an easy way for your visitors to recommend your posts to their friends right from your blog.
