Need Adwords BH Campaign Tips

Heya folks. I'd need some general guidance when it comes to BH Ads on Adwords. I succeeded on my first try on a churn burn account but haven't succeeded after. I have a general idea as to what to do but I feel that I am missing something. I'll explain more once we get in touch.

Issue has nothing to do with payment method, so I won't need any help with that.

I'll pay for this. PM me and I'll explain everything.
