I found this tool from my perusing the economic blog a The Big Picture. We all know that search engines use algorithms to decide which web sites should show up first, and which should be placed lower. In fact there is a whole business of Search Engine Optimization (SEO) dedicated to ranking your website higher in the list. The higher you are in the list, the more visits you will receive and potentially you will receive more ad revenue.
PageRankGraph helps you understand how these rankings are calculated, by showing the sites that link to a domain, with an estimate of how much influence each site has on the target domain’s score.
The lines in the graph represent inbound links that are boosting the target site’s ranking. The more juice a domain is delivering, the thicker and stronger the connection is. This means that the most helpful domains are drawn close to the center of the picture, while less important ones are left on the edges. If you mouse-over each domain, you’ll see a tooltip giving more information.
You can see that informationisbeautiful.net has a really strong connection with Vizworld. That is because they have 7 links to Vizworld. This is a nice little tool that you can find at PageRankGraph.
