Types of site maps

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. Alphabetically organized site maps, sometimes called site indexes, are a different approach. For use by search engines and other crawlers, there is a structured format, the XML Sitemap, which lists the pages in a site, their relative importance, and how often they are updated. This is pointed to from the robots.txt file and is typically called sitemap.xml . The structured format is particularly important for web sites which include pages that are not accessible through

s use the same protocol, 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.Joint announcement
from Google, Yahoo, Bing supporting Sitemaps 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. XML Sitemaps have replaced the older method of "submitting to search engines" by filling out a form on the search engine's submission page. Now web developers submit a Sitemap directly, or wait for search engines to find it. Regularly submitting an updated sitemap when new pages are published may allow search engines to find and index those pages more quickly than it would by finding the pages on its own.

If a website's navigation is built with Flash, an automated search program would probably only find the initial homepage; subsequent pages are unlikely to be found without an XML sitemap.
