Income note: Online-business results vary. No income level is promised or guaranteed by this publication.
Use constraints as the filter
If you like research and publishing, affiliate content may fit. If you have a specific solution to package, digital products may fit. If you enjoy recurring publishing, an audience model may fit.
No universal winner
The appropriate model depends on skills, resources, audience access and willingness to perform the work each mechanism requires.
