Affiliate Marketing Secrets

To be honest, when I read the title of this blog post at SEO.com in my reader, I was expecting more. However, it raises a great point we don’t often hear about.
The idea of using averages to measure out the competition level of a niche/vertical/industry.
Anyone doing it this way?
Or are you mostly relying on data provided from SEO Elite, Market Samurai, TT, and manual indicators right now?
SEO.com hasn’t been known as the best SEO resource site on the web, but they revamped a few months ago and have been doing a much better job from what I have seen.
