Google Sitemaps
If you have not heard yet Google offers a service where you can submit an xml sitemap of your web sites to their engine for crawling. This could be a big improvement for ASP.NET site builders. It is no secret that search engines have a difficult time spidering dynamic web sites. With this tool you can submit you dynamic urls that contain qery strings to their engine and supposedly they will crawl these pages. If you go to google and click about you can obtain the specs. for you xml submission. There are even attributes for importance and update frequency. We have submitted a couple of sites and are waiting to see the benefit of doing so.
Have a great day,
