Site Maps 

A site map (or sitemap) is a graphical representation of the architecture of a web site. [1] It can be either a document in any form used as a planning tool for web design, or a web page that lists the pages on a web site, typically organized in hierarchical fashion. This helps visitors and search engine bots find pages on the site.

While some developers argue that site index is a more appropriately used term to relay page function, web visitors are used to seeing each term and generally associate both as one and the same. However, a site index is often used to mean an A-Z index that provides access to particular content, while a site map provides a general top-down view of the overall site contents.

Benefits of sitemaps

Site maps can improve search engine optimization of a site by making sure that all the pages can be found. This is especially important if a site uses Macromedia Flash or JavaScript menus that do not include HTML links.

Most search engines will only follow a finite number of links from a page, so if a site is very large, the site map may be required so that search engines and visitors can access all content on the site.

XML Sitemaps

Google introduced Google Sitemaps so web developers can publish lists of links from across their sites. The basic premise is that some sites have a large number of dynamic pages that are only available through the use of forms and user entries. The sitemap files can then be used to indicate to a web crawler how such pages can be found.
Google, MSN and Yahoo now jointly support the Sitemaps protocol.

For example, think of a forum that is using dynamic pages. Google would only return less than 100 result without using sitemap. Once sitemap is provided, there are more than one millions pages result. Since MSN, Yahoo, and Google use the same protocol now, having a sitemap would let the three biggest search engines have the updated pages information. [2]

The Sitemaps Protocol allows a webmaster to inform search engines about URLs on a website that are available for crawling. A Sitemap is an XML file that lists the URLs for a site. It allows webmasters to include additional information about each URL: when it was last updated, how often it changes, and how important it is in relation to other URLs in the site. This allows search engines to crawl the site more intelligently. Sitemaps are a URL inclusion protocol, and complement robots.txt a URL exclusion protocol.

Sitemaps are particularly beneficial in situations

• when it is difficult for users to access all areas of a website through a browseable interface. In these cases, a search engine can't find these pages. For example, a site with a large "archive" or "database" of resources that aren't well linked to each other (if at all), only accessible via a search form.
• where webmasters use rich AJAX or Flash, and search engines can't navigate through to get to the content.

The webmaster can generate a sitemap containing all accessible URLs on the site and submit it to search engines. Since MSN, Yahoo, and Google use the same protocol now, having a sitemap would let the three biggest search engines have the updated pages information.

Sitemaps supplement and do not replace the existing crawl-based mechanisms that search engines already use to discover URLs. By submitting Sitemaps to a search engine a webmaster is only helping that engine's crawlers to do a better job of crawling their site(s). Using this protocol does not guarantee that your webpages will be included in search indexes nor does it influence the way that pages are ranked by a search engine.

The Sitemaps protocol is based on ideas[1]from Crawler-friendly Web Servers [2]
