It is important to shop around for the best lines when betting on sports. This is money-management 101 and will help you get the most bang for your buck. Sportsbooks set their odds according to their own preferences, so some will have better lines than others. For example, the Chicago Cubs may be -180 at one book and -190 at another. While the difference in odds is small, it adds up over time.

The first step in finding a good online sportsbook is to research its reputation. Look for user reviews and see what people are saying about the site. Also, make sure that the site is licensed in your state and offers a variety of betting options. In addition to offering a great selection of games and wagers, the best sportsbooks will offer fast cash-outs and bonuses.

A good sportsbook will have a wide range of sports to bet on, including major sports and popular minor ones. It will also feature a number of alternative lines and props. Moreover, it will offer a mobile application that makes placing bets easier than ever. Some sites will even have a live chat support staff to assist you with your questions and concerns.

Another thing to keep in mind when shopping for a sportsbook is its customer-loyalty (CLV) programs. While many sportsbooks will reward loyal players with free bets, other sites will use CLV to target high-risk customers. These are customers who have a history of losing bets or betting on teams with low expected win rates. These bettors can damage a sportsbook’s profits, so it is important to protect its margins.

In-game betting is a great way to disguise your play at a sportsbook and thwart their efforts to track your CLV. This is because the odds move quickly in-game, making it difficult for sportsbooks to track your action. In-game betting also allows you to place bets during halftime and commercial breaks, when the lines are less volatile.
