How can I search for blogs + ezines based on niche AND popularity?

[-- TW]

Here's my plan...

I have an audio cd info product for a niche.

I want to get it reviewed by legitimate blog owners and ezines in that niche (read: influential). But I want to optimize my efforts by sending the cd only to bloggers and ezine owners who have relatively *large* readerships.

I know how to find blogs + ezines -- but how to I determine what their (actual!) readership is? How do I make my search as easy as possible?

Thanks for any advice on this!

PS: Have you done a plan like this -- and, if so, what other advice could you give me? Thanks again.

TW, just a few ideas off the top of my head.

To figure out readership, you could use Compete rank. Check out Compete, then plug in the site's url and you'll get a rough estimate of that site's traffic. Granted, it's just a ballpark guess and traffic doesn't necessarily equal readership, but that could serve as one "data point" at least.

You could also use Google Reader (www.google.com/reader) to search for blogs in your market. Whenever you find sites using Google Reader's search feature, it tells you the number of subscribers to that feed.

You could also do the same thing with Technorati (Technorati: Front Page).

Honestly, not sure if there's a straightforward way of finding the info you're looking for, but hopefully one of these will help move things along for you.
