The IIS Team has released another cool product for IIS 7. A few days ago The IIS Team released the beta of IIS Search Engine Optimization Toolkit. The toolkit provides you with a number of features which can help you ensure that your site follows best practices with regards to how search engines crawl and parse your site as well as providing features for generating robots.txt files and sitemaps.
Carlos, the person behind the toolkit, has more information about the release here as well as a great video giving an overview of the Site Analysis feature of the toolkit here. ScottGu also has a walkthrough post up on his blog here.
