Blogger Feeds as Sitemaps with FeedBurner (and Google Webmaster Tools)

...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 other platforms, other feed URL variations that are not redirected are what you need to provide.

Sitemap Ping Submission

When your sitemap is updated, these are the URLs to ping the search engines (replace [your sitemap web address] with your URL):

Google

http://www.google.com/webmasters/tools/ping?sitemap=[your sitemap web address]

Yahoo

http://search.yahooapis.com/SiteExplorerService/V1/updateNotification?appid=YahooDemo&url=[your sitemap web address]

MSN Live Search

http://webmaster.live.com/ping.aspx?siteMap=[your sitemap web address]

Ask

http://submissions.ask.com/ping?sitemap=[your sitemap web address]

moreover

http://api.moreover.com/ping?u=[your sitemap web address]

According to the sitemaps protocol, the URL to submit a sitemap to a search engine is supposed to be:

<searchengine_URL>/ping?sitemap=sitemap_url

but many search engines don't seem to actually accept ping submissions this way.

Google Sitemap Validation Tool

Might be good for checking if your Google sitemap is written properly. It's basically an XML validator, with a more focused purpose.
