If you are monitoring your Pagerank status or just want to know more about how the different search engines are ranking your site, you should try out UrlTrends, which has a simple web-based tool that outputs some nice graphs for the different search engines. There is also a tool for displaying your site’s pagerank, for your blog or site.
What I liked best about UrlTrends is that it shows multiple search engines and the results page is clear and simple.
