Ask HN: I tested an idea with AdWords, are the result good enough to work on it?
So here are the results: in three days I got 245 visitors (all from ads click-through) and 27 conversions (people that left their email) for an 11% conversion rate. I spent $127 for a CPC (cost per click) of $0.64 (in particular $0.94 for search terms and $0.57 on the display network, that is the ads on third party web sites). The CTR (click through ratio, how many click per ads diplayed) was 0.07% (0.62% for search terms, 0,06% for the display network). Interestingly, ~75% of the clicks came from the display network, unfortunately I was an idiot and cannot track conversion from display vs. search (hey, it was my first AdWords campaign!).
So the big question for you guys is: are these numbers good enough to say, yeah, I'll go work on this? Or more in general, what are good numbers for an experiment like this? Thank you folks!
