Comparing the Best Online Sports Betting Sites / What To Look Out for When Comparing Online Bookmakers
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.
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.
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.
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.
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.
The sports industry is massive, and there are so many different types of sports you can watch, play, and bet on. Online bookmakers try to cater for a diverse audience, which is why they offer a wide range of sports on their sites. Here are some of the main ones you can choose from:
Esports: Another section at an online bookmakers you might often see is eSports. This works in the same way as betting on real sporting events, however it focuses on tournaments surrounding competitive video games.

Political and Economical Events Betting: Online bookmakers don’t just focus on sporting event markets. You can also bet on a wide range of other current events in the world.

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:
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.

Sports betting carries unique risks because it combines gambling with genuine sports knowledge. The feeling that you “know” a sport can create overconfidence and lead to larger, more frequent bets than you would place at a casino. In reality, even expert sports analysts rarely sustain long-term profitability from betting.
Use a staking plan — Never bet more than 1-2% of your total bankroll on a single event, regardless of how confident you feel about the outcome.
Avoid accumulators as your main strategy — Accas offer exciting potential payouts but have extremely low hit rates. The bookmaker margin compounds with each added selection.
Do not bet on your own team with emotion — Emotional attachment to a team clouds judgment. If you cannot be objective, skip the bet.
Beware of in-play betting — Live betting moves fast and encourages reactive decisions. Set strict limits for in-play wagers or avoid them entirely.

Find answers to the most common questions about The Best Sports Betting Sites below.
Yes. There is no limit on how many bookmakers you can place bets on, so if you like more than one of the sports betting sites we review, you can have an account on both of them.
There are various reasons why you should set limits at online bookmakers. They are available to help you control spending, avoid chasing losses, limit your time spent, and manage your payouts.
Licensed and regulated bookmakers will have a ‘Responsible Gambling’ section on their website. This often provides punters with information and resources regarding addiction if they’re struggling, as well as self-limit options to control their gambling.
There are many great licensed online bookmakers in the industry, but Casinofy’s favourite options that you should check out include Mr. Play, BetVictor, Bet365, and William Hill.
It is hard to determine what the ‘best’ sports betting site for football is, as they all have their own standout features. However, we recommend trying Bet365, William Hill, Betfair, or Paddy Power.
Fractional odds (e.g., 5/1) show your profit relative to your stake — a £10 bet at 5/1 returns £60 (£50 profit + £10 stake). Decimal odds (e.g., 6.00) show the total return including your stake — a £10 bet at 6.00 returns £60. Decimal odds are simpler for comparing value across bets and are standard at most online bookmakers.
A parlay or accumulator combines multiple selections into one bet. All selections must win for the bet to pay out. The odds multiply together, creating larger potential payouts but significantly lower probability of winning. Bookmakers love accumulators because the house edge compounds with each added selection. Use them sparingly for entertainment, not as your primary strategy.
For the vast majority of bettors, no. Bookmakers build a margin (typically 5-10%) into every market, which means you are statistically expected to lose over time. A small percentage of professional bettors sustain profitability through sophisticated statistical models, but this requires significant time, data analysis, and discipline that recreational bettors rarely maintain.
