How much can you charge for banner spaces?

There's a nice little article by Yaro Starak that I came across here:

How Much Should You Charge For Advertising On Your Blog?

It may give you a good starting point on things to think about.

It all depends on the quality of the traffic, the niche and the retention of the visitors. Is your site a comedy site? If so, a banner ad may be be quite cheap because the demographics of the audience varies. If however your site is niche specific, then you can charge quite a bit i.e. $200 a month.

I once had a niche site about hot tubs. I ranked number one on Google but the Adsense earnings were quite low so instead of creating any more banner ads and making peanuts, I decided to charge hot tub sellers per lead. I used to get around 150+ unique visitors a day and I managed to get 60 people a day to join a list of mine.

A month down the line, the email list grew to 2,500. I then sold the leads to various hot tub companies for $50 a lead. Needless to say, I made quite a bit of money from this business.

What I'm trying to say is that banner ads may not always be the best option depending on the type of site you have. If you have a product niche site, you can always capture emails and sell them as leads.

I usually come up with pricing myself and base it on a number of different factors..

-Traffic
-Will the banner be rotating or not
-How many banner spots will there be
-Judgement on clicks based on my current setup

In my game site I charge 100$ per banner (I have three banners per page).

That is a great article you shared, stoltingmediagroup. Thank you! Very insightful!
And, it also states what I already was about to say: it depends on traffic, rankings and testing the price would be a great idea before you decide on a final price!
