What is a sports betting bonus?

Many online sportsbooks offer a bonus as an incentive for new customers to sign up.  Not all betting companies offer them.  

What are the different kinds of sportsbook bonuses?: Bonus Bets, Deposit Bonuses & Enhanced Odds

There are three main types of sportsbook bonuses: the deposit bonus offer, the risk free bet offer and the enhanced odds offer, sometimes called an 'Odds Boost'.  

For a deposit bonus promotion, the sports betting company offers to match the customer’s first deposit up to a certain amount.  In this case, if the terms of the offer are met, the bonus amount itself may eventually be withdrawn by the customer as real money.

For a bonus bet promotion, the sportsbook offers bet credits that a new customer may place as they wish.  If the bonus terms are met, only the proceeds from a successful bet may be available to eventually withdraw as real money.  The bet credit stake amount shall return to the bookmaker.

For an enhanced odds promotion, the sportsbook offers odds that are several times higher than normal for a customer’s first ever bet or for a bet on a specified match result, usually a big game.  There are often limits to the maximum stake amount that may be placed for enhanced odds promotions.

The provider that I want to sign up with does not offer a bookmaker bonus. Why?

Every betting site or bookmaker approaches their business plan in a different way.  Sometimes, a company decides that the way to grow and serve their desired customer-base is to offer certain kinds of bonuses.  Conversely, some companies decide that they prefer to deliver value back to bettors through odds that are higher on average over time.  

If you have noticed that your sportsbook of interest is offering great odds and a great potential payout for your picks, but no bonus is listed for them, you might want to think of that higher potential payout as your bonus.  This is how that betting company is delivering value to you.  A new customer bonus can be nice, but in the end, higher odds could matter a lot more.

How soon will I be able to withdraw my sportsbook bonus as real money?

This definitely varies from sportsbook to sportsbook and is the main reason you need to read the bonus terms and conditions.  Generally there are two main criteria to satisfy before you may withdraw any kind of bonus as real money: the minimum deposit and the roll over requirements.  

Once you have made a minimum deposit, you will need to ‘roll over’ your deposit amount a specified number of times before you will be eligible to withdraw the bonus as real money.  For example, if a sportsbook requires that you ‘roll over’ your deposit amount six times and your deposit was €100, you would need to place wagers with total stakes of at least €600 before the bonus might be eligible for withdrawal.  

With some bookmakers, the bets that qualify toward this roll over requirement must have odds above a set threshold, perhaps at decimal odds of 1.50 or higher.  In other words, bets on heavy, heavy favorites may not qualify toward earning your potential bonus.  All of these stipulations are defined in the terms and conditions.

In the end, remember that these bonus offers are meant to provide new customers with added value toward enjoyment of continued play with your sportsbooks of choice.  The various kinds of bookmaker bonuses are not intended to represent free cash for you to instantly withdraw.  

Sports betting bonus promo codes: Are codes really required?

Some companies do use sports betting bonus promo codes and some do not use codes at all for their new player offers.  Each new customer bonus offer has its own terms & conditions.  As part of these terms, you may be shown or quoted a promo code that you will need to enter as you sign up for your account.  If you are quoted a code, you know you will need to enter it at some point in your registration process to get your bonus.  If you do not see reference to a code in the offer terms, then you should not need one. 

Do not be misled by the potential existence of a promo code input field as part of your sign-up process.  Oftentimes the betting site sign up screens just have an input field for a promo code built-in so that they may introduce a bonus code easily at some point in the future.  Simply pay attention to your offer terms for whether a bookmaker bonus code is quoted.
