This Is What Makes a Good Online Sportsbook
Online sports betting is offered around the world at hundreds of different betting sites. Whether you live in the USA or abroad, you have probably encountered different betting sites, but may not know what exactly to look for when choosing one over the others.
Our testing process of each sports betting operator included a variety of criteria. Before all other things, we wanted to make sure that every sportsbook we are testing is safe and legally available to American players. For this reason, we looked for proper gaming licenses in various American states and certificates of approval by third party monitoring bodies.
Apart from the sheer safety and regularity of the sites, we also wanted to make sure that the bettors who sign up would actually enjoy a good time. For this reason, we gave the highest ratings to those sites that offer a wide range of betting options across various sports and markets as well as reasonable odds for all of the markets on offer.
We also tested operators based on other criteria, such as the bonuses and promotions they had for their players, the customer support they provide and the ease of banking both in regards to the deposit and withdrawal options. Only the operators that got the best ratings in all these categories could be considered for the title of the best online sportsbook USA at AmericaGambles.
The Best US Online Sportsbooks
Determining the best US online sportsbook was not an easy job, as there are simply so many different bookmakers now licensed in the country. Each state in which online sports betting is regulated now issues its own licenses and we had to test them all and decide which site players in each state are best off at. After many hours of testing different sports betting sites, we came up with a definitive list of online betting sites that offer the best service in each of the states.
Betting Offer & Odds
The characteristic of the best online betting sites in the world is that they offer many different betting options and do so at great odds. The betting sites that tested best in our reviews are those that offer the widest selection of sports and competitions as well as best prices on all the bets.
At our leading sports betting sites, players can place wagers on all the popular American sports like football, basketball, baseball and hockey as well as other sports such as soccer, golf, darts, volleyball, handball and numerous others. What’s more, all the major competition in each of these are covered in full, with numerous betting markets offered for every game that is of any international significance.
Of course, players are also on the lookout for a good price on their bets, and we made sure to include all the bookmakers that offer top betting odds. Without good odds, betting does not make sense and our experts frown upon sites that undercut their users. Only bookmakers whose betting odds can compete with the best of them are included in our top bookmakers list, so you will not be losing any value if you join any of them.
In-Play Betting
Live or in-play betting is the preferred betting method of thousands of sports bettors around the world. With the option to bet on ongoing matches, players can now enjoy games live and make bets as the action is going on. This goes far beyond simply betting and allows players to use their insights into the sport they are watching and try to make meaningful predictions.
We tested each operator's live betting platform and rated how they compare against each other. We found that most betting sites that are regulated in the US offer plenty of in-play betting options and markets. The top rated bookies will give you a chance to bet live on any major sports event within the USA and abroad, so your options will be wide open.
Mobile Betting
There is nothing punters enjoy more than making their bets on the go and with ease. Mobile betting allows for this and the best bookmakers absolutely must offer a reasonable selection of mobile betting options. A good mobile platform for Android and iOS devices is one of the priorities each bookie must fulfill to be listed in our top US bookmakers listing.
Our rating criteria for mobile bookmakers was not just the availability of a mobile betting app, but also the selection of markets offered in these apps, the usability and ease of navigation, and overall user experience. We wanted to find mobile bookmakers that allow access to the cashier and all other parts of the site through the mobile device.
Welcome Bonus & Promotions
Possibly the biggest advantage of betting online instead of live is the ability to capitalize on massive betting bonuses that online bookmakers offer. This is the one area in which most US online bookmakers gave us a nice surprise, as they all add plenty of value to their players, offering amazing welcome deals and plenty of additional promotions.
If you join the top bookmakers listed here, you will be in for a proper treat. Welcome bonuses for US players add hundreds of dollars to real money balances and make betting more profitable and easier. The wagering requirements of the US bookies are far better than those in European sites, so rest easy knowing your bonus money is almost as good as cash.
Payment Methods
Betting sites included in our top US bookmakers listings offer a wide range of methods for both deposits and cashouts. Some of the numerous payment options are available to players for both deposits and cashouts include the usual credit cards and payment systems like PayPal, Paysafecard and PayNearMe.
All payment methods that are available are also eligible for the welcome bonus, with no exceptions. This means you will be awarded the bonus when you make your first deposit regardless of the payment method you use, which is sometimes not the case with online gaming operators in the rest of the world.
Registration Process
Players looking to join the top US bookies will need to undergo a reasonable registration process, which starts with them coming to the operator's site and clicking a Join Now or Register button. Once they do so, they will be prompted with a registration form which requires some basic player information including name, phone number, address and partial social security number.
The registration process takes no more than a few minutes and is completely noninvasive. Once this process is completed, players may proceed to make deposits, claim bonuses and place wagers. However, keep in mind that all information provided during the registration process may be subject to a confirmation process at a later date, which is why it is very important to be truthful about your personal info when first signing up.
Bonus Conditions
We already mentioned that the thing that makes this one of the best online sportsbook bonuses is not the sheer size of the bonus but rather the terms and conditions associated with it. Welcome bonuses for US players tend to have some of the best bonus conditions in the world, with extremely low wagering requirements and very few restrictions. The money you get from the top bookmakers in the US is almost as good as real cash, and wagering it just one time is usually all it takes.
These amazing conditions give players a great way to try betting for real money with no real risk and keep any potential winnings after the betting is one. Many bookmakers around the world force players to wager their bonuses many times over, thus diminishing their value, but American bookies are not in the business of forcing their players' hand.
Limits & RTP
Another important factor that we took into account when rating US bookies was the size of deposits, cashouts and bets that can be made by the players. We wanted to make sure to list sites that offer everyone a fair chance to play on their own terms. This means the low stakes bettors can enjoy their bets and the high rollers can also make their big sports bets without a hassle.
Fortunately, plenty of US sites offer both options, allowing for deposits ranging from very small to massive ones, and making weekly cashouts a non-issue for most. We also looked into the overall return across the board and looked for sites that offer the best RTP in all the sports. We were able to find bookmakers that not only offer great odds on premium matches, but simply don't take a big margin on their bets altogether.
Security
Player security is an imperative for AmericaGambles and it appears to be one for all US regulated sites as well. The operators runs a tight ship when it comes to keeping players from the US safe and they only offers real money gambling in those states in which they have a license to do so. Beyond that, players are only allowed to gamble with play money and enjoy the site for fun.
States with legal Sportsbooks
All players who want to play for real money must confirm their physical location by downloading a separate program that tracks their GPS location. The sites are protected by SSL encryptions and additional firewalls that protect player data and prevent any third party intrusions or hacks from being successful.
