Almost every affiliate who fails does so for one of a short list of reasons. None of them are about the commission rate.
The audience mistakes
Promoting everything. An affiliate who recommends every product recommends nothing, because the recommendation carries no information. Refusing to promote things is what makes promoting something mean anything.
Chasing the highest rate rather than the best fit. A 3% commission on something your audience actually wants beats 20% on something they don't, every time.
Building on rented land with no exit. If your entire audience lives on one platform and that platform removes you, you had a channel, not a business.
The content mistakes
Leading with the link instead of the value. People decide whether to trust you in the first fifteen seconds, and a pitch in that window ends the decision badly.
Making content only for buyers. The people searching how something works outnumber the people searching where to buy it by an order of magnitude, and they become buyers later.
Never updating anything. In this niche a guide goes stale in weeks. An out-of-date recommendation is worse than none, because someone will act on it.
The trust mistakes
Overstating safety. Telling people something is permanently undetected is the fastest way to lose an audience, because it will eventually be untrue and they will remember who told them.
Hiding the affiliate relationship. Disclose it. Audiences in this niche assume it anyway, and being upfront costs nothing while being caught costs everything.
Not testing what you promote. Recommending something you have not used is obvious to viewers faster than most creators expect, and it is unrecoverable when it gets someone banned.
Frequently asked questions
What is the single biggest mistake?
Promoting something you have not tested. Everything else is recoverable; that one costs you the audience.
Should I disclose that I earn commission?
Yes. It is expected in most jurisdictions and audiences here assume it regardless. Disclosure costs you nothing and being caught concealing it costs you the channel.
How many products should I promote?
Few enough that you have genuinely used all of them. That number is usually smaller than people want it to be.
