Comparing the Best Online Sports Betting Sites / What To Look Out for When Comparing Online Bookmakers

Comparing the Best Online Sports Betting Sites / What To Look Out for When Comparing Online Bookmakers

• Reputation: If you’re familiar with the online betting world, you’ve probably heard about a few of the brands you can choose from. They each have a general reputation, so it’s always best to choose a platform that you’ve heard good things about. You can always check the reputation of the brands on the Casinofy website before you start comparing sites.
• User reviews: The best way to find out how good a sports betting platform is, is by seeing what other punters have to say about it. You can either rely solely on the Casinofy reviews, or you can venture even further at review sites like Trustpilot or other general forums where punters come together and share their opinions.
• Bonuses: It’s always good to try out a sportsbook before you start spending much of your real money, and bonuses are a great way to do so. Ensure you’re signing up for an account at a betting platform that offers a generous welcome bonus that gives you a chance to try before you buy, as well as exciting ongoing promotions to maintain the thrill.
• Odds quality: Odds are the best way of determining where you should place your bets, so you want to ensure you’re getting the highest quality odds in the market. The best way to determine this is by checking whether most of the bigger platforms share similar odds. If the odds are way off, then this is probably a sports betting site you should avoid.
• Customer support: No matter how good an online sportsbook is, you sometimes need a helping hand. Whether it’s to ask questions about the welcome bonus or you’re suffering from a technical issue, you want to ensure the website you choose has a team that can provide you with assistance. Look out for 24/7 live support and responsive customer service.
• Payment methods: In order to place bets at one of these sites, you need to deposit money into your account first. And you can only do this if the platform supports your favoured payment method. It’s best to select an online bookmaker that accepts a wide range of payment methods and also offers fast withdrawals with minimal fees.
• Events selection: Imagine signing up for an online sports betting site only to find that it doesn’t cover your favourite sporting events of the year. That’s why you should do your research in advance to ensure you’re never disappointed. Casinofy’s reviews provide you with information on all the sports and events each platform offers, helping make your search easier.
• Functionality: The best type of online casino and sportsbook is one that you can use with ease. This means a user-friendly interface, exciting layout, and functionality on a wide range of devices. Look to see if the website offers its own dedicated app for your smartphone or tablet or even if it is compatible with a mobile browser so you can bet on the go.

What is an Online Bookmaker?

A bookmaker is an individual or institution who takes bets from punters. They often offer a wide range of different betting options, but the most simple bets involve having odds for one outcome, another outcome, or a draw.

When you give them money and place your bet and that bet wins, they’ll pay you back your initial bet plus whatever extra funds you’ve won. An online bookmaker is someone who offers these services online via an app or website.

Sometimes, an online bookmaker has a brick-and-mortar shop you can visit, too, but it’s easier to get access to them anywhere in the world when visiting their website. You can view the odds for games any time, day or night, and even sit and watch live betting options where the odds change in real-time.

The History of Sports Betting

Believe it or not, sports betting actually has quite an extensive history that dates back to the ancient Greeks. The Greeks were always looking for new ways to embrace entertainment, and that’s when sports betting came to fruition. They introduced heads or tails, tilia or checkers, and dice games, especially when it came to determining the outcome of gladiatorial games.

What the Greeks started was then picked up by the Romans. They were massive gamblers who put together even more elaborate gladiator fights in arenas packed to the brim with crowds and many betting opportunities. This then followed into the Olympics, where punters would place bets on wrestling and chariot races.

The first formal sports betting events began in the 18th century, which often featured horse racing as audiences loved the thrill and competitiveness of the sport. The Jockey Club helped develop horse racing in 1750, and that’s when they started introducing wagering requirements alongside bets. Horse racing was then standardised by the American Stud Book in 1868.

Sports betting started to make waves across the globe in the 19th century when the US, England, and Germany jumped on the bandwagon. Since then, more and more physical bookmakers have been popping up worldwide, and online sports betting emerged in the late 1990s and 2000s.

Now, there are thousands of betting options on the web, and there are various options you can choose from to enhance your experience.

The Legal Requirements of Online Bookmakers

While sports betting is fun, there are various legal requirements online bookmakers need to follow to ensure it is safe as well. That’s why the EU has put together a selection of iGaming regulations each platform must follow. There are also country-specific regulations, such as all UK bookmakers needing a license from the UKGC or a license from the DGOJ if the platform originates in Spain.

Across the EU, the main regulation in regard to online sports betting is the age limit. It will depend on the country, but the minimum age usually ranges from 18 to 21. However, it’s best to check before you sign up for a site, as in Greece the legal age is 23 compared to the legal age of 18 in the UK,

Licensing is also a crucial legal requirement of many online sports betting platforms as it protects players and implements anti-fraud measures. The licensing regulations vary greatly across the EU, but you’ll often want to look out for platforms that have licenses from the UKGC or MGA.

If you are unsure of the laws of your European country, you can easily find more information from one of Casinofy’s experts or complete a quick search on your country’s iGaming licensing website.

How do Online Bookmakers Make a Profit?

You’ve probably read a few of those stories where people place a small bet on a football game and end up winning thousands. If bookmakers are paying out this much to the lucky punters, how do they make money to keep running?

Online bookmakers make a profit through a concept called the ‘overround’ or ‘vig’. How this works is the bookmakers set odds on a betting market and adjust these odds in a way that ensures a profit margin for themselves regardless of the outcome. They do this by slightly skewing the odds so that the total implied probability of all possible outcomes exceeds 100%. The surplus is the bookmaker’s margin.

So, if a bookmaker puts down a probability of all outcomes at 110%, then the additional 10% is known as the overround and their profit for that event.

Is One Bookmaker Better Than the Other?

One bookmaker can be better than its competition. This is because they are all competing to get punters to place bets on their markets, so one may offer better odds or lower margins to get you to sign up. There are also other aspects of the platform that might entice you, such as the market range, user experience and promotions and bonuses.

It’s best to always browse a few sports betting platforms before committing to one to ensure you’re signing up for the best one. This is why Casinofy reviews the biggest sportsbooks in the industry, to help make the search and decision easier for you.

Kind of Bets You Can Place at Online Bookmakers

The types of bets you can place at an online bookmaker will depend on what the individual platform offers. However, here are some of the main bets you might find:

• 1×2 Bets: This is the most simple bet you can place and purely focus on the outcome of the event. For example, if you’re betting on soccer, you’ll bet on team 1 to win (1), a draw (x), or team 2 to win (2).
• Over/Under Bets: These types of bets include predicting the total score, goals, or points of a sporting event. You will determine whether the outcome will be over or under the amount specified by the bookmaker.
• Correct Score: This bet involves a punter predicting the exact score, goals, or points of a sporting event. This is a much more difficult bet to win because it’s incredibly specific.
• Halftime/Full-time bets: Placing halftime and full-time bets means predicting both what you think the halftime outcome will be as well as what the full-time outcome will be.
• Draw No Bet: This bet reduces a punter’s risk a bit as if the sporting event ends in a draw, the bet is void, and the amount you bet will be returned to your bankroll.
• Asian Handicap: This type of bet gives a handicap advantage to the underdog or a disadvantage to the favourite to level the playing field. It removes the draw as a possible outcome.

How to Read Quotes at Sports Betting Websites

The odds of each betting market are presented in quotes on a bookmaker; however, they can come in different formats. Here’s how you can read beach of the main odds at sports betting websites:

• European Odds: European odds is the most common format used in Europe. It will read as something like 2.50. The number represents the potential return, and it includes your initial bet. So, for every unit you wager, you’ll receive 2.50 units back if your bet wins.
• Asian Odds: Asian odds, which are also known as Hong Kong odds, Indonesian odds, and Malaysian odds, are most common in Asia. It will read as something like -0.5, +0.25, or 0.80. These odds include handicaps, which indicate a team’s advantage (+) or disadvantage (-) in an event.
• American Odds / Money Line Odds: American or money line odds are most commonly used in the United States and Canada. It will read as something like +150 or -200. The positive symbol represents the potential profit on a $100 stake if the bet wins. The negative symbols represent the amount needed to wager to win $100.

Online Sports Betting Websites Bonuses

Bonuses are one of the most exciting aspects of an online sports betting platform. These are the various promotions you can make the most out of:

• Welcome Bonuses: When you first sign up for an account at an online bookmaker, you’ll receive your welcome bonus. It’s often activated after your first deposit and can include matched deposit bonuses, free bets, or risk-free bets.
• Free Bets: Punters might receive a free bet token after meeting specific criteria, such as placing a qualifying bet. You can then bet without risking your own money and potentially make a profit from the winning bet.
• Combo Boosters: Combo boosters are offered for accumulator bets – which combine multiple selections into one bet. This enhances the potential winnings by adding a percentage bonus to the total winnings if the accumulator bet wins.
• Odds Boosters: A bookmaker will offer enhanced odds on selected markets or events with odds boosters. They offer better odds than usual, increasing potential returns if the bet wins.

Online Bookmakers with the Highest Odds

You might want to find an online betting site that offers the highest odds, but there isn’t really one out there that has significantly higher odds than another. However, the betting landscape is dynamic, and odds can vary a bit between bookmakers based on their strategies, risk management, and market analysis.

There are various factors, such as spreads, which reflect the bookmaker’s margin. Bookmakers adjust odds to attract bets, resulting in fluctuations across different platforms. Similarly, odds are also influenced by real-time events that create constant changes. The best thing to do is regularly compare odds across platforms to find the best site for your wagers.
