Using FeedBurner with Google Webmaster Tools If you use Google
Webmaster Tools and expect to submit a feed as the source for a
sitemap of your blog or website, you should use your site's original
feed, and not your FeedBurner feed, for the sitemap to work properly.
Here's why:
If you use our feed stats services to track feed item click throughs,
FeedBurner rewrites your item URLs so that we can track the clicks
before sending subscribers back to your website to view the original
content. These links use the feedburner.com domain, of course.
Sitemaps expect the original domain of the website in question to be
found in the feed in order to function properly; these
feedburner.com-rewritten permalinks will not work and then cause
Webmaster Tools to report a sitemaps error. This error can be
completely sidestepped by providing your original source feed instead.
Webmaster Tools won't lack for any information or functionality as a
result, and you can keep click through tracking turned on in your
FeedBurner feed.
One other point: if you have a site whose original feed redirects
traffic to FeedBurner (for example, if you use Blogger redirection, or
you use our FeedSmith plugin for WordPress), you will need to give
Webmaster Tools the address of a feed that does not get redirected as
a sitemap source.
For Blogger users, the following general feed URL format should always
work:
http://mybloggerblog.blogspot.com/feeds/posts/default?redirect=false
For WordPress FeedSmith plugin users, use this URL format:
http://www.mywpblog.com/?feed=rss2
For all other platforms, other feed URL variations that are not
redirected are what you need to provide.
- A moot point since you shouldn't use feedburner feeds for sitemaps.
