What is a Google Site Map and Why You Sould Use It

You can use a sitemap file to tell Google about all the pages on your site and to provide information about those pages, such as which are most important and how often they change. Sitemaps are particularly helpful if your site has dynamic content, pages that aren't easily discovered by following links, or if your site is new and has few links to it.

Sitemaps helps speed up the discovery of your pages, which is an important first step in crawling and indexing your pages, but there are many other factors that influence the crawling/indexing processes. Sitemaps lets you tell Google information about your pages (which ones you think are most important, how often the pages change), so you can have a voice in these subsequent steps. Other factors include:

• How many sites link to you
• Whether your content is unique and relevant
• Our ability to crawl the pages successfully
