Finding the right credit card these days is often easier said than done. One great way to narrow things down is by focusing on credit cards that offer the best sign-up bonuses. Credit card companies compete fiercely for loyal customers, and they dangle these bonuses as a way of enticing people to sign up. And this means you can get a credit card that delivers big benefits.

To qualify for most credit card sign-up bonuses, you typically must spend a certain amount on your credit card within a specified period of time. Bonuses may be given as miles, points, statement credits, or cash back. The main advantage of these bonuses, then, is that they can make using a credit card more affordable. In some cases, you can even pretty much be paid for using the credit card — and what could be better than that?
