Sometimes, including on this forum, I read advice to use Adwords for market research. Looks simple: find a few terms that describe your product idea, see how many people are searching for it, put up an ad, see how many people click etc.
I am trying to find a niche in the analytics/reporting/bigdata space. So far, I learned that most keywords cost upwards of $2/click. But even as they get to the landing page, it is difficult to say if they are genuinly interested or are just tyre-kickers.
If anyone here has actually done this, I would much appreciate them sharing the experience, particularly about:
Does click-through-rate matter? you would probably get 1-2% CTR if you advertise snow to the Eskimos. what kind of CTR you are looking for to say a definite no or yes, if at all?
Without having a website, except a couple of landing pages, what techniques did you use to determine genuine interest?
if all you had was a contact form or phone ## on the landing page, did people actually contact you?
