Individual podcasters can figure out their audience size by examining hits to the hosting Web sites. But what about the competition? And specifically, what about those podcasts occupying better real estate on the iTunes charts?
ESPN's Bill Simmons has uttered such a refrain, as his competitive nature manifested itself in constantly checking his iTunes popularity ranking. He wondered how Apple figured out these rankings, and the only thing that most of these podcasters have figured out is that it helps to have lots of five-star fawning praise listed on the podcast's informational page. (This article from 2005 details the use of recent subscriptions to figure iTunes rankings, and this story from 2006 asks a similar question.)
Thus, recent listens to podcasts such as On the DL and The Basketball Jones have included a call for fans to write reviews to the ubiquitous podcasting interface.
The confusion between the have's and have-not's also can be confusing for prospective guests, as Dallas Mavericks owner Mark Cuban explained this week on the BS Report:
Bill Simmons: I've been trying to get you on for a year, and Marc Stein says that you didn't want to come on mainly 'cause you hate being on the phone, which I accept. That's a valid reason.
Mark Cuban: Yeah, it's not so much that I hate being on the phone. The honest answer is I'm just not a big fan of podcasts.
BS: You're anti-podcast?
MC: Yeah, it's not that people don't listen to them. Obviously, people do. But it's just, you know, there's only a few of them, yours included, that have more than 10 people that listen to them. I always felt that, If I'm going to be fair and objective, I'm going to have to do a whole bunch of them. And so, if I wasn't going to do them all, I wasn't going to do any of them.
Of course, Cuban goes on to use his opportunity to stoke an uprising in support of HDNET's battle with Time Warner Cable. So as podcasters do their best to appeal to advertisers, they might need to make two copies of that presentation and save one for audience-generating guests, as well.
