Groff "in the hole"Back in 2008, Joe Pulizzi started looking in-depth at blogs that focused on content marketing. He found 81 blogs – and the Junta 42 were the viewed as the leaders in what was then an emerging field.

Two years on and the field has exploded, with almost 400 blogs being tracked as part of the Junta 42 list. This growth mirrors not only the interest in content marketing and social media, but the general explosion in blogging as a method of communication.

Each of the blogs in the Junta42 are ranked based on a number of factors, explained as follows:

    1. The number of posts in last quarter that pertained to a content marketing topic. Those posting on 3 or more days per week received the highest number of points.
    2. Substantiveness of Posts. Here we worked to weed out posts that fell short of adding value to the collective body of knowledge about content marketing. For example, blogs that simply linked to other blogs or articles without adding new information, perspectives or ideas to the commentary received lower scores than did blogs that consistently delivered unique ideas, thoughtful insights, deep coverage, rich media and the like – you know, high-value content – to the community.
    3. Google PageRank. (All blogs were checked on the same day.)
    4. Previous Ranking.

The latest version of the Junta 42 provides a handy reference to some of the leading content marketing blogs – a very useful resource for those marketers working with social media as part of their strategy. The August 2010 top 42 content marketing blogs are:
