EatonWeb has brought together over 20 different factors that we believer are indicators of a blog’s strength and wrapped them all up into a single metric. Factors that we consider include technorati data, Google PageRank, the ratio of links to a site’s homepage as opposed to its deep links (we believe that there is a sweet spot on this ratio to rule out link manipulation), total links, estimated subscribers, Alexa ranking and more.

By combining all these factors, we think we’ve done a pretty good job at differentiating the great sites from the good sits and the good sites from the bad sites. And that’s one of the reasons that EatonWeb matters as a blog directory.
