Tips for Choosing an Online Sportsbook

Learn All You Can About The Betting Site

Read everything you can about the online sports betting platform, the betting opportunities it offers, all available sports promotions, whether it is available for mobile betting and its various payment options. You should also take time to check out its customer service options, as well as familiarize yourself with the ease of its user interface.

Furthermore, you should read through the terms and conditions of the betting site, especially in regards to the various bonuses in offers in order to avoid any unwelcome surprises. Most bonuses and site offers (for example, the sign up bonus) have a wagering requirement (sometimes called a rollover requirement), which means you would have to bet a given amount to make the bonus complete. It’s smart and prudent to find out exactly how much you need to wager before being able to cash out your bonus money.

Also, be sure to check the minimum and maximum deposit and withdrawal limits to ensure that they fit your bankroll.

Use The Betting Site’s Resource Section

If you are a complete novice sports bettor and wish to learn how to place bets, plenty of betting sites will provide you a step-by-step guide to betting. These are generally very useful and will help you start betting quickly, whether its betting on the Super Bowl in the NFL, March Madness in NCAA college basketball, Stanley Cup in the NHL, the MLB World Series, the Kentucky Derby or any other sports event.

Start with Small Bets

When learning how to bet on sports online, start with small stake bets and gradually increase the amount only after you understand how that particular bet works. In other words, manage your bankroll wisely. After all, it is your hard-earned money that is at stake here. Moreover, only bet the amount you can afford to lose, which should be funds that you have left over after you have met your other regular bills and expenses.

Keeping this in mind, you can now begin looking for sportsbook sites or other betting platforms and products that make online betting for beginners easy.

What Types of Sports Bets Can You Make?

Three of the most popular forms of online sports bets are moneyline, point spreads and totals (over/under). The information below explains each of these betting options offered at the sportsbook in simple to understand terms.

Moneyline Bets

A moneyline bet is a sports wager on which team will win a particular game. The moneyline wager is the most popular way to bet on hockey and baseball, but exists also for basketball, football and other sports. In this type of bet, the payout is the same regardless of how many runs or points scored by the team you wagered on.

Placing moneyline bets requires that you first understand the American odds system, which always uses a 3-or-more digit whole number expressed as either positive or negative. The reason there are positive and negative moneylines is that the two teams are often not equally matched.

A negative moneyline, for instance, represents how much a bettor must stake to profit $100, with a line of -180 requiring a $180 bet in order to profit $100. Therefore, if your bet is successful, you keep the $180 you staked plus the extra $100 in winnings. Meanwhile, a positive moneyline is how much a $100 stake will pay. For example, if you stake $100 on a line of +160, if your bet wins you keep the $100 you staked, plus an extra$160 in winnings.

Point Spread Bets

Point spread betting is the most popular way to bet on the two most frequently wagered upon sports in the United States, namely football and basketball. The basic idea behind point spread betting is to make the sports game closer to a 50/50 proposition by adding a handicap.

For example, you could find they New York Giants +10.5, and the Philadelphia Eagles -10.5. How this works is that the favorite team always has a negative value alongside it, and the underdogs a positive value. In our example, the Philadelphia Eagles are the favorites to win by 10.5 points in this game. Meanwhile, the underdog in this game are the New York Giants, which has a +10.5 value, meaning online sports bettors will profit if the New York Giants win the game outright or lose by 10.5 points or less.

All point spread wagers also have a price or commission, which otherwise not stated by the sportsbooks, or Las Vegas sports books is assumed to be -110. In other words, risk $110 to profit $100, or if simplified, every dollar bet you bet, the sportsbook receives 10 cents, rather than an even 50.50 line in which you bet a dollar to make a dollar. This extra price you’re charged is referred to as vig or juice and is how the sportsbooks make their profit.

When betting online, you’ll commonly find point spreads that have half points involved (example -2.5 / +2.5), thus ensuring there is no way for a sports bettors wager to be tied.

Totals - Over/Under Bets

Totals betting is the one of the easiest sports bets to understand. Here you bet on whether the total number of points scored by both teams combined during a game will be over or under the posted betting total.
For example, this bet might be over/under 8.5 runs in baseball; over/under 5.5 goals in hockey; over/under 40.5 points in football; over/under 200 points in basketball, etc. Similar to point spread betting, unless otherwise stated these bets are assumed to be offered at -110 (risk $110 to profit $100). Also similar to point spread betting, it’s also quite common in totals betting to see each option have a different price, such as over 5.5 -130 / under 5.5 +110.

How Do You Win at Sports Betting?

This online sports betting guide is meant to help you understand the basics of the industry.

Just know that betting on sports is extremely competitive, and people often beat the odds by exploiting leaks presented by online betting sites. Nevertheless, this is in an industry where it is hard to be profitable in the long run,and very few are destined to make a living betting on sports. In fact, the majority of sports bettors tend to be what we call recreational bettors.

On the plus side, there are tons of good bonus offers and promotions available with online sports sites that can make your hobby profitable. Just be sure to stay disciplined, though, and never risk any more than a couple percent of your bankroll on any given game.

What are Other Ways to Bet On Sports?

The online sports betting industry continues to grow across the United States, with an increasing number of states offering legal, regulated options. This includes Pennsylvania, West Virginia, New Jersey, Delaware, Rhode Island, Mississippi and New Mexico. New York, Indiana, Iowa, Illinois, Michigan, Arkansas, Oregon and of course, Nevada, have also largely legislated legal online sports betting.

Meanwhile, the rest of the country have bills that have been introduced, but not passed, or bills that have been recently passed. The only places that have no interest in legal online sports wagers are Utah, Wisconsin and Idaho.

If you’re not a resident or visiting one of the legal online sports betting states, or are not comfortable using online gambling sites, you could always use either a Las Vegas sportsbook or alternatively, a local sportsbook to take your action.

Many of the top sportsbook sites will post sports-like odds for non-sporting events. Popular events to bet on outside of the sports arena include Oscars & Awards betting, betting on the stock market, the weather and politics. such as US Election betting odds.
