Engage more and help your visitors to follow your stream of content by adding a simple, but powerful button that links to your Google Profile in your WordPress site.
Google Webmaster Central offers a really simple tool where with just three steps, you can generate an HTML code that you can paste in your WordPress (or any other website). You can choose from four different button sizes: 16px, 32px, 44px, and 64px.
The installation of this code is really easy: in WordPress, log in and navigate through Appearance to the Widgets section. There drag-and-drop a Text Widget to one of your available Widget area — this could be for the sidebar, footer, etc. –, then paste the code, click Save, flush your cache if any, and refresh your site to reveal your new Google Profile button.
