MSN Microsoft Live Search, and Yahoo have all agreed to use the same sitemap protocol:
In an encouraging act of collaboration, Google, Yahoo and Microsoft announced tonight that they will all begin using the same Sitemaps protocol to index sites around the web. Now based at Sitemaps.org, the system instructs web masters on how to install an XML file on their servers that all three engines can use to track updates to pages. This should make it easier to get your pages indexed in a simple and standardized way. People who use Google Sitemaps donÃ¢â‚¬â„¢t need to change anything, those maps will now be indexed by Yahoo and Microsoft.
The announcement from Microsoft’s Live Search blog has no word on how to submit yet: “we are working hard to release full support in 2007.”
The Sitemaps protocol itself is being released under an Attribution-ShareAlike Creative Commons license – which should encourage others (CMS software projects, blog platforms, etc. as well as other aggregation/search sites) to leverage it as well.
