The folks at AdvertisingAge released their latest Power150 list this morning, which now features the power of PostRank analysis!
There are already some noticeable changes in the listings, and we’re hoping our real-time analysis will keep the rankings current and interesting for a long time to come. Our congratulations to the bloggers on the list! (We’re not even playing favourites with the Canadians.) 
The AdAge blog post has a great explanation of how and why they integrated PostRank into their analysis, and what it brings to the list and its rankings:
Why’s PostRank so great? For one, unlike other metrics, they provide real-time data. We’ll only be grabbing it once a day like any other metric, but you can be reasonably sure that your recent hot post will be accounted for. But here’s an even bigger reason: we have a specific time window. For each blog, we’re grabbing PostRank scores for only the previous 30 days, an intentionally small window of time. We wanted to make the Power 150 more dynamic and current, and, by basing 1/3 of your overall score on recent activity, we’re hoping this will affect rankings in three ways:
Level the playing field a bit. If you’re a king now, you could be demoted within 30 days. If you’re at the bottom, you could enter the upper reaches yourself within a month, if you do well enough. Of course, the latter still won’t be easy, but hopefully not the insurmountable task it once was, because recent successes will count for more and long-accrued success a little less.
Encourage people to keep up with their blogs. If you stop blogging for a month (as some of you have — tsk, tsk), your score will suffer. We don’t necessarily want to punish you for taking a break, but we think those who are still active and working should have an advantage.
Give a better picture of what’s happening now. We want the Power 150 to be a more dynamic place, a better reflection of the fluidity of conversations on the web rather than a calcified “Who’s Who.” It’s a pretty lofty goal, but this our best shot so far.
Additionally, there’s more information here, as well as a chance to win Power150 prizes!
We’re thrilled to be a key part of the Power150 analysis and list, and we hope we can help keep the list timely and relevant and help people even more to Read What Matters.
