Learning PPC as a beginner - Where do I start?

I'm a total beginner at PPC and want to become a pro.

Where to I start? I have looked on Udemy and have come across the following courses which look solid:

https://www.udemy.com/course/the-ultimate-google-adwords-training-course/https://www.udemy.com/course/google-ads-masterclass/
However it appears these have outdated content and we're made around 2018. They still get solid reviews though.

Or would I be better of becoming 'Google ad certified' and doing the course Google provide?

Any advice greatly appreciated.

It depends on what you want to sell though PPC, there are different creatives, Sales funnel and stuff Like that. Please tell us more so we can provide you the best solution.

Well, I may ask the same question.

Been in the game as PPC for 1.5 years and run ads only for small business who owned their stuff.
The goal for me right now - to learn as much as possible to be able to advertise:
- white hat offers as affiliate like e-com, saas and etc
- grey hat to run affiliate offers too
- black hat


Can someone direct me to a book or course?

Thanks
