What your budget for the product/course?

What is your budget for advertising?

Any traffic source preference?

Instead of looking for a complete step by step guide to CPA (Ive seen more CPA products than probably anybody on this forum and I've yet to see a paint by number CPA product), look for a good traffic guide and then master that traffic source...CPA revolves around traffic.

By it's very nature, CPA has an incredible number of variables in each campaign that make a paint by numbers product virtually impossible.

So master a traffic source and then monetize it with CPA...find a good traffic course!

Definitely do some research into what you want to do first, then research who is best in that area.

Look into free traffic via Youtube.

Do a search on WarriorForum, there is a lot a free & don't worry about a product until you have made a good effort on your own.

I am with Kenster, study traffic and particularly pay per click. If you buy a course by one on pay per click. Or just invest in the war room, Alan has a great course in there all about pay per click marketing.

See you didn't have to go very far after all.
