What are some things you can do to maintain a good credit rating?

To maintain a good credit rating, pay your bills on time and keep your credit utilization ratio below 30% by using only a portion of your available credit. Regularly check your credit report for errors and dispute any inaccuracies. Avoid opening too many new accounts at once, as this can negatively impact your score. Lastly, consider keeping older accounts open to lengthen your credit history.
