On the left is a graph that was created by Steve Broback at the Business Blog Summit. It compares the alexa traffic rankings of Autoblog to the hardcore, and long running motertrend.com.
What does this graph prove? It depends... some would like to think its more evidence of the blog's business potential. Personally, I'm skeptical, because for one thing, most businesses don't have anything interesting to blog about (thus, nobody will read their blog).
However, I do think think there are certain industries that could capitalize effectively on weblogs. In particular, certain professionals, such as dieticians, personal trainers, and consultants have a unique opprotunity to break through google by way of weblog. More importantly however, a good weblog that is directed towards the interests of potential customers (read posting daily fitness tips) might have an exponential effect on traffifc to their site.
However, back to my skepticism: a lot of businesses who might be interested in using weblogs usually miss one key point: blogs don't perform magic tricks. You have to update them, and your content better be worth reading. More notes later, I'm running late to a sexy party at Austin's Hole in the Wall.
