Google has now has their very own “Add To Google” button. This allows users to add a site’s feed(s) to the Google Reader or Google’s Customized Home Page.
The code is as simple as this:
<a href=”http://fusion.google.com/add?feedurl=[SITE FEED]“><img src=”http://buttons.googlesyndication.com/fusion/add.gif” width=”104″ height=”17″ border=”0″ alt=”Add to Google”></a>
But if you need help or just want more information, you’ll find that here.
You can see the button in action on the right side of my site.
