Google AdSense for Feeds (FeedBurner) announced that going forward all links’ll be “301 Permanent Redirect.” Some users selected to use a 302 redirected link, as opposed to a 301 redirected link, to obtain better tracking. Google has made this change for the URLs to become “more compatible with search engines that crawl feeds,” and will consider these to be additional links that should be used in determining the popularity of your site. This update should not change number of clicks that come to your site from your feed nor should significantly affect number of clicks FeedBurner tracks for you. If you run FeedBurrner for your web site feeds, you don’t have to make any changes. Google has already made the 301 change for you.
