XML Sitemap Generator for Google Webmaster Tools
The tool is free if you are trying to index a site that has less than 500 pages of content. There is a paid version of the tool for sites with more than 500 pages. The options are fairly clear and I think the XML looks pretty simple. This seems to be a good option for either the lazy or the XML inept.
Give it a try and let me know how it goes. It would seem that for folks who are trying to get some very basic SEO in place an auto-generated Sitemap is not a bad idea. As the search engine will spider the xml sitemap and index it your basic search relevance and ranking is more likely to be elevated.
I’ve just entered mine and will see how it progresses. I may have to replace it in a while after I’ve added more content.
