I know I'm approaching this from potentially the wrong angle - but I can't just sit around all day waiting for a profitable problem to fall into my lap.
I've been checking out categories on capterra and plugging them into google keyword tool and jaaxy to get some basic data. Have checked first page of google and currently trying to determine whether I could get on page one based on the SEO of the competition.
I have read plenty of articles from software entrepreneurs about niche research, but thought it would be interesting to hear a take from general internet marketers. Appreciate any insight!
