Google subcribed links give you an easy way to stay in front of your customers with Google accounts, as well as show up on the first page of the search engines without any search engine optimization, pay per click, or anything other than a few minutes time on your part.

Simply, provide an xml, rss, or tsv (tab separated values), and sign up at:  http://www.google.com/coop/subscribedlinks/newsubscribedlink/

Simply input your feed, and you are basically done.

There is a plugin for Wordpress, Google Subscribed Links, which can be found  here:  http://wordpress.org/extend/plugins/google-subscribed-links/

Install this plugin in Wordpress, then submit a link formatted like:

http://coolbubba.com/blog/feed/?coop=1

Whereas, normally the feed for wordpress would be www.coolbubba.com/blog/feed with the plugin installed, format you url with the /?coop=1 and it works great.
