First read the ad policy to see whats allowed and what not to reduce the risk of getting banned. You can also spy your competition with the Facebook ads libary If you didn't knew yet.
Always warm up your accounts with some budget (Just 1-2$) are ok. But never use payment method twice.
1 Account = 1 payment Method.
Best would be If you have aged Accounts with activies at this point. The older the account is the more facebook trust you.
Another thing to keep in mind is that you never should have unpaid balance like fb tries to get money for your ads but they cant get the Money. Thats one of the badest things because you loose Trust.
