If you follow the steps in part I of this guide to find an audience, you'll likely end up with a number of options.
But: Not every audience is an audience you can sell to.
Choosing an audience is very personal. Still, there are tricks to quickly check if an audience has business-potential.
Size is Relative
The first thing to look for in an audience is size.
Size is relative of course. A super niche audience that is very engaged, for instance professional mountaineers, doesn't need a lot of people to have business potential.
Audience-size is about dollars as much as headcount. If members spend thousands of dollars each, your audience doesn't have to fill a football stadium.
Growth
Audience size is a static number. It doesn't tell you anything about the change in size over time.
Is it growing? Or is it shrinking?
