i get around 10k uniques a month and around 15k total hits a month, and 55k pageviews to my website per month. how much should i be charging for advertising?
In all honesty, I don't think you can set a fair price unless you review the content of your website and your niche. Sure anyone can shout quick figures off the top of their head based on your traffic statistics, however depending on what your site is based on, you may very well be able to charge much more than $25.00/month.
I will have to agree with JKhoury, it is hard to determine for sure. It seems like most people have said $25 so I would be inclined to try and get away with a little more than that. If you don't get any takers you can always lower the price. Hope this helps
