I just found this great tutorial on making great sitemaps for my wordpress blogs. Some of the benefits of having a good sitemap are:
"* The user can quickly find a specific post he wants anytime he wants
* The user can quickly see and get an idea how big the blog is get an overview on what the person is writing about.
* All your posts are linked to from a single page to make sure they are not forgotten by the search engines. Basically PageRank is passed to all of them and they are not buried deep down in the archive. If there are no links to your old posts Google will put them in the supplemental index which is not good at all. "
In this tutorial you will learn to make 3 different sitemaps for your wordpress blogs. Read the full tutorial by going to
