Other than Google Analytics, which came out this week, Google also made some changes to Google Sitemaps. The new features amount to essentially some feedback as to what are the most popular search terms for you site, and what if any errors some of the sitemap urls are generating.

In order to enable the new options, you must verify your site by creating a specifically named html file on your site. The new features are helpful, but may be considered very insignificant when compared to Google Analytics.
