Introducing CliqueSite.Ads
I'm not yet sure how I'll price it and license it. I want it to be affordable because this stuff isn't really brain surgery, it's just time consuming to build. I will say that other similar products (those based on .NET, anyway) are ridiculously over-priced.
CliqueSite.Ads can serve most ad formats that I can think of. It will do any size, pop-ups, rich HTML, etc. It does frequency and session capping. It aggregates data so you don't end up doing massive counts for every little report. The only thing I haven't added that might be useful is day/time blocking to restrict ads to certain times.
Like I said, if you're game, drop me a line! I hope to get something out by the end of the weekend.
