1) What kind of site you have. (For example, editorial or e-commerce pages are likely to get more clicks than forums do for the same number of page views.)
2) The nature and turnover of your audience. (In other words, do your visitors have money to spend, and are there enough new visitors each month to prevent the "ad fatigue" that occurs when readers see the same ads day after day?)
3) Advertisers' bids for keywords on your topic. (If bids average a dollar, you'll make more money for the same number of clicks than you will if advertisers aren't bidding higher than the 5-cent minimum).
The only way to know how AdSense will perform on your site is to apply, get accepted, and try the code on your pages. Adding the code should be easy, and you can view your earnings as the clicks come in, so why not just give it a try?
That is the most important factor IMHO, even if you have an audience that clicks twice as much as somebody elses, the amount that advertisers pay for CPC makes all the difference.
Try it and find out.
