I had a number of potential markets for my product, being the the flagship anti-oxidant, anti-inflammatory, anti-aging and sports performance product, which is a bit general. Going by that people buy to gain pleasure or avoid pain I wanted to target people who are experiencing discomfort, quality-of-life issues eg fatigue, on a daily basis who want rapid, simple relief. There’s high relevance to medical conditions but had to skip those for the legal reasons.
I did some keyword research to see what kinds of search numbers there were for a few areas (anti-aging, sport/excercse recovery) and detox related terms were up the top of the list. (A hangover cure/remedy was a runner up, probably best to just run the ads on a saturday and sunday for that one!)
I did a bit of research i n the forums (Jim, killer tip to filter the serach resutls by discussions only!!) to get some ideas of what peoples experiences, mindset, doubts and queries are when looking for supplements/diets to detox. I also liked this market because I have an idea for releated valuable free report with an associate affiliate offer. Also ties in to the hangover niche if I do that next, will have some content to leverage.
