About the new sitemap format

With the release of version 4 of the Google Sitemap Generator Plugin for WordPress, the type of the generated sitemap changed from a single sitemap file to a sitemap-index file with sub-sitemaps.

The old sitemap format

The old sitemap looked like the following table. It included all the content of your blog in a single file.

The new sitemap format

The new sitemap format looks like the following table. Instead of including all content in one huge file, the sitemap index-file links to several sub-sitemaps as described in the official Sitemaps Protocol.

What are the benefits?

  • The required resources on server-side are lower. Instead of generating a huge sitemap, only small pieces are served on request.
  • Your sitemap can contain more content. Each sitemap is limited in size and the number of URLs inside.
  • The sitemap loads faster. Since the sub-sitemaps are much smaller than the old sitemap, they obviously load faster.
  • Less traffic. The search engines can see when the sub-sitemaps have been modified.

FAQ

  • Do i need to submit each sub-sitemap to Google? No, the plugin will automatically tell Google about the index file. Google handles the sub-sitemaps automatically!
  • Will the new sitemap format hurt my rankings? No. The new format is an official sitemap format defined by Google.
  • For some reason, I don't like the new format. Can I change to the old one? There is not really a reason to not use the new format, but if you really don't like it, you can use the 3.x version of the plugin!
