I have a website that right now is doing a grab bag mixture of content; fitness, health, entertainment, humor and so fourth.

Am I affecting the amount of money I could be making by doing this? I'm getting like global $0.25 to $0.35 CPC overall, even with nutrition and exercises, health and wellness galleries and articles.

Am I better off creating one site for entertainment and humor, then another for all of my health and fitness stuff?

Also, does the traffic in high volumes affect my earnings? Meaning am I just flat going to get lower CPC and RPMs with high traffic?

I am getting 600,000 to 800,000 page views daily.
