Google, Yahoo and Microsoft partner to help webmasters

This was a surprise news. The competetors working together. That too Google,microsoft and yahoo. But it is true. They have decided to be partnered to simplify how webmasters and online publishers submit their sites' content for indexing in the companies' search engines.

A site map is a file that webmasters and publishers put on their sites to guide the search engines' automated Web crawlers in properly indexing their Web pages.
Site maps are particularly useful in highlighting to crawlers the dynamic Web content that is served up on the fly.

Crawlers generally index content contained in static Web pages without problems, but often they have difficulty with dynamic content, such as the one that is generated as a result of a search query.

Google, Microsoft and Yahoo will encourage other search engine operators, as well as makers of related software, like content management systems vendors, to support the protocol, they said.
