Build your Site Map online.
I highly recommend this service for creating your Google sitemap. www.xml-sitemaps.com lets you create your sitemap online:
- Create an XML sitemap that can be submitted to Google, Yahoo and other search engines to help them crawl your website better.
- Create a Text sitemap to have a plain list of all your pages.
- Create a ROR sitemap, which is an independant XML format for any search engine.
- Generate an HTML site map to allow human visitors to easily navigate on your site.
