How do I create a Google Sitemaps file?

Search engines need to "crawl" or "index" your site to take a snapshot of the pages that appear in the search engine.

Some search engines (most prominently Google) can use a "sitemap" file to decide how to crawl the site in a more intelligent manner (for example, by crawling frequently changed pages more often). The site www.sitemaps.org has more details about sitemap files.

You don’t need to use a sitemap file (we don’t use one on our site), but if you want to create your own sitemap file, you can generate one at http://www.xml-sitemaps.com/ if you enter just a few details about your site.
