Steve Rubel recently made reference to a ranking of PR blogs in the form of a Social Media Index. The actual listing and ordering of blogs according to various criteria was posted at Edelman’s Europe CEO blog, SixtySecondView.

Our SEO firm’s blog, Online Marketing Blog was included in each permutation of the list using a wide variety of criteria. I have yet to see so many different criteria used in any other ranking of marketing or PR blogs. That includes the AdAge Power 150 and Onalytica’s ranking of the most influential blogs, both of which include TopRank’s Online Marketing Blog.

Such lists always attract a bit of scrutiny and criticism, as they should. It keeps them honest or outs them as otherwise.
