Once upon a time I was an engineer totally scornful of effective marketing, but I have gradually gotten over it. After thinking it over, this is aggressive but within my comfort envelope. The ad is honest about being an ad, makes a straightforward commercial proposition (“Sign up for a free trial”) to an audience that I think will respond well to that, and is pretty true by the standards of marketing copy. It is designed to catch clicks only from people interested in signing up for a free trial of Bingo Card Creator, and sends them straight to a landing page where they can do just that.
I wish there was a way to dynamically generate the image such that I could provide a more exact star valuation, but in the context of a sponsored placement, “Rated 5 starts by lots” is both non-specific and true. Lots of people have used BCC, and when I ask for star ratings in internal surveys I get something like 4.8 on a volume of hundreds or thousands. I think this compares favorably with “9 out of 10 dentists agree” and other pretty banal marketing copy.
Your ad is obviously designed to deceive the user into thinking that it is an organic listing. Evil.
