It depends how you intend to drive traffic to it, It will be either profitable or not depending if you make conversions or not
I don't think there is complete guide shared for free on the forum
BUT this post can give you good intro to CPA/AM -
Click me
Create one what?
That seems odd, what is this traffic?
What are you promoting?
I see English is not your strong side, that's probably the first reason why no one clicked

Be smart
What paid traffic? Pop, push, native..?
The goal is to let your AM(Affiliate Manager) believe that you are super dedicated and will make money without him holding your hand.
You can say something like you have learned about CPA for the past year and you are ready to implement everything you have learnt.
No, I'm not collecting emails.
Ad -> Lander -> Offer
1) Yes It will be fine
2) Getting such traffic for free is gold, however I think there are other way to monetize it which will be 10x more profitable than your idea.
Also consider that if you get that much traffic you will need to DM thousands of people, Instagram won't like that
You can switch the offers, and it's good to wait till your grow more like 30-50k followers to start promoting.
That's a huge difference but could be normal.
I would check with your AM if there are any technical issues with the network or this exact offer.
I'd hate to self-promote but you can check my course

These are different ad formats, you can google "push notification ads" and "native ads" to see some pictures.
Push is doing great in 2021 It's cheap & scalabe, I am doing push as well.
I can't say push is better or native is better because they are both good. At this point I prefer push ads, someone else may rather native ads.
