Hey I've been where you've been. Signed up on CPA networks for 3 years and read but did nothing or did things half way.
About a month ago, I started taking serious action. And now the money is coming in nicely. Not a lot but its growing fast.
All of the methods work well, especially YT and SEO. IG can work too but it'll be harder.
Your problem is quite simple, you are overthinking and not taking any action to get your links out there. Stop whining and get to work. The money will come. Good luck.
