Last year we published the Sitemap 0.84 XML protocol as a free and easy way for webmasters to inform search engines about URLs on their web sites so that search engines can more effectively crawl them. We released it under the Attribution/Share Alike Creative Commons license in the hopes that other search engines would adopt the protocol too. And today, we're excited to announce that Yahoo! and Microsoft are joining us in officially supporting the Sitemap protocol.
As the web becomes more dynamic, Sitemaps will enable better and fresher search results for everyone who uses the web. For site owners, Sitemaps will help improve website visibility in search results. You can read more about this on our Webmaster Central blog.
