Help your users follow your stream of content by adding a button that links to your Google Profile to your site. Google Webmaster Central has a simple form for this: answer two questions and it generates a string of HTML to add to your web site.
If you have a blog, there should be a setting where you can add a widget with HTML code. Just paste the code created by Google at the link below in the text box for that widget. You can choose from four different logo sizes: 16px, 32px, 44px and 64px.
