Finally! A standard everyone can live with.
The three search engine giants (Google, Yahoo and Microsoft) announced that they will all be using the Sitemaps protocol to index sites all around the world.
And to help everyone out, Sitemaps.org instructs webmasters on how to go abouts installing an XML file for thier websites.
People who use Google Sitemaps don’t need to change anything, those maps will now be indexed by Yahoo and Microsoft.
