That's not a simple question to answer. The standard response would be that you can charge what you like at any point in time so long as people are prepared to pay. I have run a social networking site for a year and a half now and I have found advertisers quite reluctant to pay large sums of money. My site gains around 10,000 visitors a month, so that makes me small-fry in the web world, but I did manage to gain a few advertisers.

Many websites offer pages/directories for advertising in and charge an annual fee, something nominal like £30-50 for the year. Unless you are in a niche industry or you are dealing with high end services or products you really need to be gaining around 30,000+ visitors a month to charge advertisers decent monthly rates.

Most advertisers at that level will need you to charge them on a per thousand impressions basis, so results based, and you will need to have some fairly sophisticated software on your site monitoring this so you are able to provide them with proof of impressions and click through rates.

You could also consider any number of companies on the web that will provide you with banners from third party companies (some of them very well known) that will pay you on results (click throughs, or sign ups).

Hope this helps.
