I have been an active user of StackOverflow for a while and also make a lot of decisions about the advertising of my company's products. We have tried StackOverflow ads and are getting ready to try again -- still working to find the right ad that gets a good enough ROI.
The product is kind of a niche .NET developer SDK -- meaning only .NET developers would be interested and only a small subset of those. I can't really target better than .NET on SO (pretty much any .NET developer could be interested)
Anyway, the question is: what kind of ads on StackOverflow do you find effective or personally compelling and why? What kinds of ads do you click on?
We have tried advertising:
- a 30 day eval of the SDK
- video tutorials on how to use our product
- a 5-day e-course on the subject our SDK covers (totally non-commercial -- no product info)
- a free version of one of our entry-level SDK's
- a free version of an SDK + a coupon for a complementary product.
I am trying not to be specific about what we do.
