One of the hot new website promotion tips du jour is the Google Sitemap. This is a small XML file that sits on a website and provides information for Googlebot when it comes to visit. Is this file useful? What does it do? How do I create one? How do I get Google to find it? Well, let me tell you.
Firstly, the general consensus on whether or not a Google Sitemap is useful is that, well, the jury is still out. The official stance from Google is that this entire program is in Beta so there are no promises or guarantees. Perhaps by understanding what this file is for we can infer its usefulness.
A Google Sitemap is, essentially, an XML file that contains information on all the web pages in your site. You create this file, submit it to Google, and Google will read it. What Google does from there nobody really knows. You can specify certain parameters in the file such as the location (URL) of your web pages, when they were last modified, how often the pages are updated, and what each page's "priority" is.
Perhaps Google is relegating these Sitemap submitted results to a secondary index where they compare the results to their live index. This might let them know how people use (and abuse) the program. It is my opinion that the vast majority of participants in this program are website designers and marketers who are trying to give their clients a teenie-weenie leg up on the competition within Google. That's not to say that there isn't any value, though.
