If your site publishes feeds of its content, this page will display the number of users who have subscribed to these feeds using Google products such as iGoogle, Google Reader, or Orkut. Because readers can use other sites and aggregators to subscribe to your content, your total number of subscribers from all sources may be higher.More information on creating and managing site feeds.You can also choose to submit your feed as a Sitemap. A Sitemap is a useful way of telling Google about pages on your site we might not otherwise discover. More information about Sitemaps.Webmaster Tools subscriber stats reflect known subscribers to feeds hosted on your verified domain (http://www.example.com). FeedBurner sees all requests for your feeds. If a Google user is subscribed to the FeedBurner version of your feed (for example, http://feeds.feedburner.com/yourfeed or http://feeds.example.com/yourfeed), this information will not be reflected in Webmaster Tools subscriber stats, but it will be included in your FeedBurner stats.
