Thanks for this @Mallard. I have realized that this is not one avenue that people like to pursue but I guess there are many ways of achieving something and a blend of most of these is vital. Would you say there's a future for this kind of advertising?One of my sites uses fixed price advertising at $10 for a month per ad slot. It gets more revenue than the Adsense on it, but the site is very niche with an established audience. The only thing is that we don't always sell all the ad inventory so having Adsense or something else to fill any gaps is really important.
