For those of you bloggers who sell direct ads on your site, how do you determine your price structure? I'm really struggling with what pricing is worth. I run a relatively small blog (1700 subscribers, 20-30K page views each month and about 4,000 unique visitors) in a niche topic and am just looking for a starting off point. Much of what I've seen varies DRAMATICALLY from one blog to another with no real rhyme or reason.
I blog traditional foods and Weston A Price at Nourished Kitchen. See my healthy recipes.
