Affiliate Marketing Secrets

It can be if you target a microniche like seniors with fibromyalgia, moms with fibromyalgia, etc. To me, any niche can be a good niche with the right amount of traffic and good solid content.

Many work-at-home scams prey on seniors like yourself, especially those under financial stress.
You would do better to avoid this route and look for an actual job doing chores or admin work for minimum wage. You are more likely to take home some money this way.
If you persist in looking for an online job with little, or outdated, marketable skills, you are bound to be scammed eventually, in one way or another.
