Create the Google site maps XML to provide information about your site to Google.
Site Map Builder allows you to create the Google site maps XML needed within your root directory in order to provide information about your site to Google. This XML sitemap must have some syntax that Site Map Builder will generate for you.
It did not create a complete sitemap. My site has a number of major sections, all accessible via the main page and most heavily interlinked. SMB.NET found fewer than half of the pages, requiring the remainder to be added to the map manually. If it's not going to produce a complete map, there's not much point to using it.
Summary
It will work great for most people.
