Eliminate 'nuisance balances'
"A good way to improve your score is to eliminate nuisance balances," says John Ulzheimer, president of consumer education at CreditSesame. Those are the small balances you have on a number of credit cards.
This works because one of the items your score considers is just how many of your cards have balances, says Ulzheimer.
So, charging $50 on one card and $30 on another, instead of using the same card (preferably one with a good interest rate), can hurt your score, he says.
The solution to improve your credit score is to gather up all those credit cards on which you have small balances and pay them off, Ulzheimer says. Then select one or two go-to cards that you can use for everything.
"That way, you're not polluting your credit report with a lot of balances," he says.
