what to expect from CPM revenue for website

[charley]

I have a successful website related to a videogame and hand held gaming gadgets. The website is a resource for the games.



I've tried to monetize the traffic, but since most people viewing the site have the videogame, AdSense CPM is very low. I've also tried casino advertising but I've had no luck so far with that either.

- what should I expect for CPM rates on this kind of venture? I have a lot of room to add pages, so I could see 25 pageviews a visitor as a possibility once the site is more fully developed.

- Would it be out of the question to expect a CPM of more than $2 or so to monetize the PPC traffic I'm using?
