Add google+profile button to 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 four different logo
sizes: 16px, 32, px, 44px, and
64px. Google Profile Button | Google Webmaster Central
