Ways To Improve Your Credit Score

Pay on time.
Limit how much available credit you use to 30% per card, 10 % across all cards.
Avoid opening store cards since that will lower the average age of your accounts.
Keep old cards active, since the length of your credit history is important for your score.
Do not apply for multiple cards over a short period of time.
Spread charges across cards rather than using one card heavily.
Mix up the types of debt you take on, including mortgage, auto loans or other installment loans.
Keep your debt level low compared with income.
