Google alerts can be used in an awesome way to display current news topics that contain specific search phrases in a SharePoint RSS feed. This can be used to show fresh and up to date dynamic content on a SharePoint site.
Simply go to http://www.google.com/alerts (And sign in with your Google account)
Update the search terms, type and volume. Change the Deliver to “Feed”
Click Create Alert
Click RSS Feed and Copy the URL
Add the URL to a SharePoint RSS viewer web part and watch as Google works for you!
If you don’t like the HTML code in the RSS feeds or dislike the Google Alerts header use my custom XML code available here to neaten up the appearance.
