Whats the Sitemap Protocol, and how does it work?
The Sitemap Protocol is an open technical standard developed by Google and widely supported in the search engine industry. It provides a mechanism for producing a list or map of all your webpages and automatically communicating this “sitemap” to search engines. Such Sitemaps provide a comprehensive list of pages on a website for search engine crawlers, not simply a directory to help a user navigate a website.
