Rules that have earned me a great credit score: Pay at least the minimum every month Keep your card active (make purchases monthly) Keep your revolving utilization below 30% (how much you’ve used of your total credit line) Have different lines of credit (installment loans like car payments, a credit card, etc.)
It’s dumb, but it’s a lot simpler than it seems. I had zero knowledge besides the revolving utilization tip going into my first credit card and my score is in the 760s range. Also don’t be tempted to over spend when your credit limit is increased. Mine is at like $16k now because discover is predatory as hell but I’ve never had more than $5k on it at one time
