Affiliate Sites in Highly Competitive Niches

One of the things that I've "learned" in the past couple of years of building websites is that some niches have a hell of a lot more competition than others. Life Insurance, for example, is just a tough niche to break into. My takeaway from that is that it probably makes more sense to be a big fish in a small pond that a small fish in a big pond.

However, this article makes a couple of interesting points while encouraging people to just into "big niches":

• More offers to split-test
  
• Higher payout due to more competition
  
• Longevity -- these niches aren't going anywhere
  

Interesting thoughts.
