ONPAGE OPTIMIZATION:: SITEMAP
|THIS IS ONE OF THE ON PAGE FACTOR TO SET YOUR WEBSITE ON THE FAST TRACK TO SUCCESS.|
A Sitemap is an XML file that lists the URLs for a site, It can be
(1)A document in any form used as a planning tool for web design,
(2)A web page that lists the pages on a web site.
Sitemap 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 particularly beneficial on websites where:
* some areas of the website are not available through the browsable interface,
* webmasters use 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.
The Sitemap Protocol format consists of XML tags. Sitemaps can also be just a plain text list of URLs.
Sitemap contains just one URL and uses all optional tags.
Sitemap's elements has some specifications;
Here are three of them:
(2) Element: "lastmod"
'Always' is used to denote documents that change each time that they are accessed. 'Never' is used to denote archived URLs. This is used only as a guide for crawlers, and is not used to determine how frequently pages are indexed.
In my coming post I'll tell about the sitemaps-search engine submission.
