Yes, Yahoo! supports the Sitemaps format and protocol as documented on www.sitemaps.org.

You can provide us a feed in the following supported formats. We recognize files with a .gz extension as compressed files and decompress them before parsing.

• RSS 0.9, RSS 1.0, or RSS 2.0, for example, CNN Top Stories
• Sitemaps, as documented on www.sitemaps.org
• Atom 0.3, Atom 1.0, for example, Yahoo! Search Blog
• A text file containing a list of URLs, each URL at the start of a new line. The filename of the URL list file must be urllist.txt; for a compressed file the name must be urllist.txt.gz.

Yahoo! supports feeds for mobile sites. Submitting mobile Sitemaps directs our mobile search crawlers to discover and crawl new content for our mobile index. When submitting a feed that points to content on the mobile web, please indicate the encoding of the content—either xHTML or WML.

In addition to submitting your Sitemaps to Yahoo! Search through Site Explorer, you can:

• Send an HTTP request. (Send using our ping API.)
• Specify the Sitemap location in your site's robots.txt file. This directive is independent of the user-agent line, so you can place it where you like in your file.

Yahoo! Search will retrieve your Sitemap and make the URLs available to our crawler. Sitemaps discovered by these methods cannot be managed in Site Explorer and will not show in the list of feeds under a site.

Note: Using Sitemap protocol supplements the other methods that we use to discover URLs. Submitting a Sitemap helps Yahoo! crawlers do a better job of crawling your site. It does not guarantee that your web pages will be included in the Yahoo! Search index.
