NFL Betting Lines – How to Find the Best Lines at a Sportsbook


Sportsbooks are companies that accept bets on various sporting events and then return the bettor’s winnings. They are an important part of the gambling industry and serve as a source of income for both the owners and the employees. The best online sportsbooks offer a steady stream of weekly and recurring promotions that include free bets, odds boosts, profit boosts on straight bets and parlays, insurance offers on props and parlays, “bet and get” bonuses and other specials. These bonuses increase a bettor’s chances of ending the year in profit.

The betting market for NFL games begins to take shape almost two weeks before kickoff when a handful of sportsbooks open their so-called “look ahead” lines, which are usually set at a low level. The lines are based on the opinions of a few sharp managers, but not a lot of thought goes into them. These look-ahead limits are typically a thousand bucks or two, which is more than most punters will risk on a single pro football game but significantly less than what a professional would be willing to wager.

Once betting opens, the lines at sportsbooks will change frequently as money comes in and out on both sides. This is why it’s critical to shop lines and find the best prices. A few cents difference in a team’s line at one sportsbook may not make or break a bet, but those small differences add up over time.
