I reported this morning on a tool at Webmaster Eyes that overlays Google’s PageRank bars on top of your pages. The tool works somewhat like how Google Analytics, ClickTracks and other Web analytics pages overlays click through data on your most popular links.
For example, plug in searchenginewatch.com and take a look at the overlay chart. I tend to like to plug in a URL of a sitemap page, so you can get an overview of your complete site PR distribution page by page. I attached an image of my sidebar navigation with the PR plots overlaid for your quick review. Try it yourself at http://www.webmastereyes.com/, notice there may be issues with PR bar placement for some sites.
Again, as I noted in my previous post, Google PageRank is not the final say in ranking well in Google. Google claims it is used for determining crawl frequency and other ranking aspects. But many SEO professionals have uninstalled the Google Toolbar, to make a statement about PageRank’s worth.
