How to get the traffic

Like most people that start with affiliate marketing I have problems. Mostly in the traffic department.
I have very limited funds, like less than $100 a month I can put into this until it becomes profitable enough to self sustain. And as such I don’t find paying for ads to be viable. But I am not against it.

In your experience, how have you been able to get out there and get the traffic? Especially if you don’t want to post 100 tiktoks promoting a random product, I want an automated process that I can fire and forget, not work on for hours every day. Might as well work a 2nd job at that point. Would see more return at this point too.
