I'm sorry if this question has already been asked.. (I'm sure it has!).. but I did some searching and couldn't really find any succinct answers.
Basically, I am trying to find out how to find out if there is a "market" for a product or idea.
For example, let's say that I have an idea of creating (and then selling) a ebook on how to make puzzles.
How would I find out the information I need to know if this would be a good idea or not?
- How to find google stats on how many people search using the keywords of "how to" "make" "puzzle", etc..
I hope that makes sense?
Basically, I get lots of ideas.. and some of them I think might possibly be good.. but I don't want to invest too much time/money into something if there is no demand for it.
Please note -- I'm not asking for information on how to market my service/product. What I'm trying to find out is if there is any demand for my service/product. I don't want to spend weeks/months/thousands building my product, then doing advertising.. and finding out that there is no market for it.
Yes, I know.. everyone wants to know how to do this... which is precisely why I am posting here and hoping the replies will not only be useful to me.. but other creative folks with ideas, too.
