Types of Online Betting Offers

Online betting promotions come in many different formats. Knowing the various types of promotions offered at betting sites will allow you to determine if any particular offer is worth taking.

As the name suggests, a free bet offer gives you a certain amount of money that you can use to place any bet you want. For example, online sportsbooks may offer a promotion to anyone willing to register an account and make a deposit, giving you an extra $10 that you can use to bet on any sporting event.

Free bets are also often given to customers in return for taking certain actions such as participating in a special promotion or wagering on a certain event.

Betting deposit bonuses are offered in return for you funding your betting account. In most cases, the size of your deposit bonus is determined by the size of your first deposit as a percentage. For example, a 100% deposit bonus means that if you deposit $100, you will receive an additional $100 in bonus funds.

Betting reload bonuses are a sub-category of deposit bonuses. The only difference is that whereas first deposit bonuses are reserved exclusively for new customers, betting reload bonuses are open to new and existing customers alike.

Any special offer that does not require you to make a deposit qualifies as a “no deposit betting bonus.” The most common example of no deposit betting offers a sportsbook giving you some money or a free bet just for registering an account. No-deposit bonuses at online betting sites give you a chance to practice placing a bet and the opportunity to win real money without having to risk your own money first.

Risk-free bets involve placing a bet with your own money first, understanding that if your bet is a loser the sportsbook will refund you an amount equal to the size of your original stake (up to a predetermined maximum amount). If your bet is a winner, you get to keep the winnings, and nothing else happens.

Cashback bonuses give a percentage of each bet back to you as cash in your account in the form of betting rebates. Whether you win or lose does not matter; you get back a percentage of every wager placed. For example, if you were to wager $100 with an 8% rebate offer, you would get back $8 the next day no matter the outcome of your bets. This type of incentive is most often associated with horse racing betting.

Odds boost promos at mobile sportsbooks temporarily increase the payouts for certain wagers. For example, if the Broncos were originally priced at +120 to win their Sunday game, an odds boost might enhance their odds to +150 to give bettors extra value on that market.

Price boosts are also frequently offered for parlays if you meet certain conditions. An example of this would be a sportsbook promising to pay an additional 20% above the normal payout if you place a parlay bet consisting of 5 legs or more.

Mobile betting operators usually ramp up special offers during major sports betting events such as March Madness, the Kentucky Derby, and the Super Bowl. Major sports events present prime opportunities for sportsbooks to attract new customers, some of whom will become regular punters.

It is not surprising that betting sites come out with special promotional offers revolving around major sporting events. These offers take many forms, but all are geared to incentivizing new customers to sign up and bet on the event in question.

A mobile betting bonus promotion offers extra cash or a free bet in return for placing your first bet via your mobile device or tablet. In most cases, all you need to do is log into your betting account via a connected device and place a bet.

Numerous reports from the industry have found that mobile sports betting is a primary driver of growth for operators today.

Customers who bet on sportsbook apps via smartphone tend to place more bets than those who only wager from the desktop. Thus, online betting sites are keen to introduce their mobile apps to customers, often via mobile betting bonuses.

High-stakes gamblers may be able to get custom bonus offers just by contacting customer support, telling them how much you want to deposit, and asking if they could work out something special just for you. This is more common than you think. Besides, it never hurts to ask.

Referral or “refer a friend” betting bonuses are an incentive program designed to reward players who refer other players as new customers.

Important: Understand the impact rollover and other terms and conditions attached to any betting offer before accepting.

Bonuses and other promotions offered by online betting sites always come with terms and conditions attached.

Most of the offers found at mainstream sports betting sites are legitimate, but there will always be a few things that you need to know. Make sure always to read the terms and conditions before you accept any particular offer.

Read the fine print on all betting bonus offers, and you’ll see the words “rollover,” “play through,” or “wagering requirements.” The rollover requires you to place X amount worth of wagers before you can withdraw any bonus cash or winnings associated with the bonus.

For example, a $10 free bet offer might come with a 2x rollover requirement. In this example, you would need to place $20 worth of wagers before you can withdraw winnings from that bet—the lower the rollover, the better the offer.

Deposit bonuses, enhanced odds offers, and most other specials come with an upper limit on the amount of free cash you can get with the offer. This is always worth noting. It might save you the aggravation of making a huge deposit only to realize that the 100% match bonus you just claimed was only good for up to $50 extra.

Betting bonuses rarely come with identical terms and conditions. We recommend reading through all fine print. The key here is to ensure that any offer you plan to claim is compatible with what you want as a customer. If an offer looks too good to be true, you’re probably missing something.
