The Ad Age Power 150, a ranking of top marketing blogs, has become more dynamic with today’s introduction of the PostRank metric. The new metric, developed by the folks at AideRSS, is based on social engagement or how interesting/relevant people find content to be. To measure such a thing, PostRank uses an algorithm that combines numerous online activities such as Digg, Twitter, Facebook, del.icio.us, RSS subscriptions, post comments, etc. This is the first Power 150 metric that scrutinizes your blog on a post-by-post basis… and adds a lot more daily excitement to the list.
Please read Charlie Moran’s detailed Ad Age blog post about the Power 150 upgrade and feel free to comment. Because we crave your feedback, anyone who comments on this blog post, Charlie’s post, our Facebook group or sends me a related comment via Twitter @toddand before Sunday at noon (Chicago time) will be entered in a raffle to win Power 150 prizes (t-shirts and pens). I’ll update this post with the winners then.
Most of your questions about why PostRank was added and it’s impact on the list can likely be addressed by reading Charlie’s explanation. Questions about the new metric will probably best be answered by PostRank’s “How It Works” page, but I’ve highlighted a graphic below from the PostRank website that lists several examples of engagement data sources that are included in PostRank. Bottom line, we’re hoping this new metric helps keep the Power 150 relevant and useful. More new features are in the works so stay tuned.
