What's you nich? What's the PR? What size ad? How many ads on one page? The questions could go on and on. Advertise spots for $50 a month if nobody's interested lower it to $30. If spots are filling up fast raise the price to $75, pretty simple supply and demand.
Hi guys,the blog is at http://www.menshealthzine.com Thanks, any suggestions, I'd welcome! Thanks again
Just like what everyone else is saying, we need traffic stats. Depending on how much traffic you get makes the difference between charging $5 or $50. Lets hope that your traffic is high and you can charge as much as possible and still get people to purchase advertising.
Hook your blog upto Google Analytics, or if you already have post some stats here. I'm sure that way you'll get a much more accurate estimate
It all depends on the traffic you get, alexa ranking, Google Page Rank and so on.For a new blog maybe $10 per month for a banner or a link would be reasonable.
It highly depend on what is your PR and the unique traffic you get per day. If you have around 1000 unique visitor/day you can sell the ads space for $200/month minimum
