A site map of what links from the English pedia's Main Page.Sitemap of GoogleA site map
(or sitemap
) is a 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.
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 Adobe 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.
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, Yahoo and Ask now jointly support the Sitemaps protocol.
Since MSN, Yahoo, Ask, and Google use the same protocol, having a sitemap lets the four biggest search engines have the updated page information. Sitemaps do not guarantee all links will be crawled, and being crawled does not guarantee indexing. However, a sitemap is still the best insurance for getting a search engine to learn about your entire site. [2]
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.

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 on websites
- where some areas of the website are not available through the browsable interface, or
- where webmasters use rich Ajax or Flash content that is not normally processed by search engines.
The webmaster can generate a Sitemap containing all accessible URLs on the site and submit it to search engines. Since Google, MSN, Yahoo, and Ask use the same protocol now, having a Sitemap would let the 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 web pages will be included in search indexes, nor does it influence the way that pages are ranked in search results.
- Google first introduced Sitemaps 0.84 in June 2005 so web developers could publish lists of links from across their sites.
- Google, MSN and Yahoo announced joint support for the Sitemaps protocol in November 2006. The schema version was changed to "Sitemap 0.90", but no other changes were made.
- In April 2007, Ask.com and IBM announced support for Sitemaps. Also, Google, Yahoo, MS announced auto-discovery for sitemaps through robots.txt.
- In May 2007, the state governments of Arizona, California, Utah and Virginia announced they would use Sitemaps on their web sites.
The Sitemaps protocol is based on ideas[1] from "Crawler-friendly Web Servers".[2]
The Sitemap Protocol format consists of XML tags. The file itself must be UTF-8 encoded. (Sitemaps can also be just a plain text list of URLs. They can also be compressed in .gz format.)
A sample Sitemap that contains just one URL and uses all optional tags is shown below.
<urlset xmlns="http:www.sitemaps.org/schemas/sitemap/0.9" xmlns:xsi="http:www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http:www.sitemaps.org/schemas/sitemap/0.9 http:www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd"> <url> <loc>http:w3c-at.de</loc> <lastmod>2006-11-18</lastmod> <changefreq>daily</changefreq> <priority>0.8</priority> </url></urlset>
If Sitemaps are submitted directly to a search engine (pinged), it will return status information and any processing errors. The details involved with submission will vary with the different search engines. The location of the Sitemap can also be included in the robots.txt file by adding the following line to robots.txt:
Sitemap: <sitemap_location>The <sitemap_location> should be the complete URL to the Sitemap, such as: . This directive is independent of the user-agent line, so it doesn't matter where it is placed in the file. If the website has several Sitemaps, this url can simply point to the main Sitemap index file.
The following table lists the Sitemap submission URLs for several major search engines:
Sitemap files have a limit of 50,000 URLs and 10 megabytes per sitemap. Sitemaps can be compressed using gzip, reducing bandwidth consumption. Multiple sitemap files are supported, with a Sitemap index file serving as an entry point for a total of 1000 sitemaps.
As with all XML files, any data values (including URLs) must use entity escape codes for the characters : ampersand(&), single quote ('), double quote ("), less than (<) and greater than (>).
