I have two niche ideas that I find really interesting. One of them has a lot of individual affiliate programs, and the other would mainly be for amazon affiliate.
They are both pretty competitive as far as I know, but I do believe that they could be profitable in the future if I manage to rank some blog posts and get traffic etc. The reason is that they are niches that are growing in popularity. However the one thing that concerns me is that there are no people running ads on google for either of them.
So my question is – how do you guys check if a niche is profitable and do you believe that a niche could be profitable even if there are no ads running.
