A sitemap is a list of

• Sitemaps used during the planning of a website by its designers

• Structured listings intended for
  search engines

Types of sitemaps

Sitemaps may be addressed to users or to software.

Many sites have user-visible sitemaps which present a systematic view, typically hierarchical, of the site. These are intended to help visitors find specific pages, and can also be used by crawlers. They also act as a navigation aid^[1] by providing an overview of a site's content at a single glance. Alphabetically organized sitemaps, sometimes called site indexes, are a different approach.

For use by search engines and other crawlers, there is a structured format, the

Since the major search engines use the same protocol,^[3] having a Sitemap lets them have the updated page information. Sitemaps do not guarantee all links will be crawled, and being crawled does not guarantee indexing.^[4] Google Webmaster Tools allow a website owner to upload a sitemap that Google will crawl, or they can accomplish the same thing with the robots.txt file.^[5]

Sample
