I'm sure that you know that I have some Google Adsense ads on this site. I don't use them too much here because I don't want them to be too obtrusive, but I figure if the couple of dollars that they provide a month will pay for this site's hosting then I'm at least not losing money. Google says that I cannot tell you to click on them, but I will say that when I visit the sites of other bloggers and I see an ad that looks like something I might be interested in I will click through.
In building the WhatIWantMost site, though, I have made liberal use of several types of advertising as you can see from the screenshot below:
In addition to the ads that you can see in the screenshot, the site makes use of a lot of other advertising opportunities as well: Amazon affiliation, Ebay affiliation, Shopping.com affiliation (later), and I think that is it for now. However, there are other advertising channels that I'd like to consider like direct sponsors and other affiliates like JobBurner. I've learned over the last few weeks that there is only so much screen real estate available and if I don't want to turn the site into a giant billboard, which I do not, I'm going to have to invest some time into coming up with some alternatives. For the www.asp.net site we use a tool called BanManPro and while it works well I don't want to invest that kind of money just yet.
Rather than add more ad placements to the site to support the additional opportunities, I'd like to have something in place that would rotate displaying Adsense ads and other ads in the small number of placements that I've already defined.
We used to have a pretty good home-built ASP banner ad system that I used on previous incarnations of this site and the DiggerSolutions site that included some good management, tracking and reporting. I wonder if I can't just take a pass at converting that.
I'll have to do some more research in this arena to make sure that I don't build something that already exists. Hmmm, the BanManPro system is starting to sound better :)
UPDATED - 3/6 5:08 PM: It looks like Jeremy Schoemaker, a popular blogger, created something like I was describing with his ShoeMoney Advertising Network. It basically just serves as a passthrough to aggregate your different ad networks to provide ad rotation, a simple implementation interface and centralized management.
