How We Go About Making Our Odds Comparisons
So, we have our task at hand. How exactly are we going to go about completing such a momentous betting odds comparison? Well, first things first, let us talk about the sports we are covering. We will be comparing odds on football, tennis, golf, horse racing, cricket, snooker and American sports (such as the NHL and the NFL). The bookmakers we will use to compare our odds are bet365, William Hill, Paddy Power, Ladbrokes, Coral, Betfair, Betfred, BetVictor, 888sport and Unibet.
The betting sites, like sports, have been chosen for their consistency. Not only are these names known for the quality of their odds, but they all cover a very wide range of markets.
We will compare 15 markets on each sport for our sports betting odds comparison. Vital to know is that all of these are To Win markets. These 15 markets were taken over three days and will be updated each month. We also try to take each market from a different game as much as is possible, but it is not always the case due to market restrictions at the time of analysis.
All of this was done to create the most accurate betting odds comparison we possibly could, so you can get the clearest idea of what is available.
Finally, before we begin, we would like to point out that a low score does not mean that a bookmaker is providing subpar odds. All these bookmakers have been chosen because of the excellent odds they provide. The competition is intensely fierce; indeed, were our randomly selected 15 markets different, you may see completely different results. What we hope though is that by doing this consistently, we can provide the best and most accurate betting odds comparison possible. With that said, let us begin.
Football Odds Comparison
It is the most popular sport in world, and it has arguably the most competitive odds. This was a surprising result with two winners, and plenty of competition amongst those mid-rankings for our betting odds compare table, showing how tight the odds race is here.
Tennis Odds Comparison
A huge victory for 888sport here, who did not manage to net a single odds victory in the football markets. Elsewhere, bet365 show their consistency coming third again, and more draws show how tough each and every odds race is.
Golf Odds Comparison
Our runner up from previous rounds, bet365 has come out and dominated this golf betting odds comparison, leaving little room for anyone else to take a victory. 888sport, though, still manages to impress in this betting odds comparison table.
Horse Racing Odds Comparison
Another amazing showing by bet365 for horse racing, one of the most coveted markets. We also finally see the likes of Paddy Power get some credit – they’ve been so close to getting the best odds on so many markets, and have often missed out. Betfair, again, impresses.
Cricket Odds Comparison
bet365 is knocked off the top spot here by an incredibly impressive showing from both BetVictor and Betfair, who manage to take a third slice of the winning percentage each. 888sport once again gets a few victories, while bet365 manages to also sneak in with some wins of their own. We can see a great amount of choice for cricket fans in the below betting odds comparison table.
Snooker Odds Comparison
It's great to see Paddy Power and William Hill get wins here, because they’ve consistently provided great odds – they just haven’t gotten the victories as often as they could have. An extremely competitive market with no one dominating force, as you can clearly see.
American Sports Odds Comparison
Another tough race here, with William Hill just taking the edge from bet365. The third place for American sports ended in a tie, and we’re really happy to see Unibet get the credit they deserve too. Paddy Power also finishes strong with a win of their own.
Overall Odds Comparison Leader board
To calculate our overall leaderboard, we take the winning percentages and add them all up. Each winning percentage is worth a point, with those with the most points winning. The winner was no surprise here, considering how bet365 completely dominated two of our fields, especially the golf betting odds comparison. That said, every site impressed. Even those at the bottom of the leaderboard came so close to winning points on so many occasions that if we ran this again, there’s a chance we would see a very different lineup, especially when you consider that close middle section.
What are the Benefits of Odds Comparisons?
Considering all the effort that has gone into creating our betting odds comparison, some of you may be wondering what the point of all of this is. Well, we haven’t spent all this time staring at spreadsheets for nothing. We aim to always provide you with the best possible help so we can improve your betting experience, and this is one more arrow in our advice bow. Let us break down five key benefits of utilising this data.
1. It Saves You Time
Unsurprisingly, this kind of betting odds comparison takes a while. You can compare odds on one market without a huge amount of hassle. However, doing so across so many of the same markets, across the same bookmakers in a space of three days in a month – that’s a different story. So, before we move onto more specific benefits, we want to preface that by putting it into the context of the work that has gone into it. Put simply, we’ve done this so you wouldn't have to. This allows you to have access to information that realistically, few bettors would ever attempt to gather themselves.
2. It Provides Value
The key reason we do this is that better odds have an inherent monetary value. This isn’t rocket science; you know that if you have more generous odds – that means that if you win – you’re going to end up with more money.
We spend an awful lot of time thinking about how best to win bets, but we should also pay attention to how to get the most value out of those bets as well. The difference can be more than you think.
Let us pick one at random as an example. In a Champions League match between Manchester City and Real Madrid, the best odds available on this market for Manchester City to win is 39/50. The worst odds are 8/11, at least amongst the bookmakers we have checked. The implied probability of 39/50 is 56.2%, while the implied probability of 8/11 is 57.9%.
That’s a whole percentage and a half difference, which is no small amount. Over many bets, those differences in percentages add up. For example, consider how large a difference in return you could see if you have a 1% to 2% difference in each pick of an accumulator. We’re all about finding you the best possible betting experience, and that means pointing you in the direction of where you are likely to find the best odds
3. It Creates Patterns
So, one of the key challenges for our betting odds comparison is that all of these betting sites are excellent – we know, it’s a rather lovely problem to have. However, in terms of this article and these statistics providing the most value, it is a challenge, because in every market we look at, any of these names could have the best odds. That is why we have checked so many across so many different sports. You’ll be able to see not only who came out the best for each, but also who came out on top overall. The benefits of providing patterns over many different markets are as important as the immediate results. This is, in our opinion, the best way of making our tables as accurate as they can be.
4. It Offers a Variety Of Bookmakers
You may wonder why we have provided such depth in terms of the bookmakers you are looking at. The reason is simple – there are a lot of factors that go into choosing what betting site is right for you. On a really basic level, you may be locked out of some betting sites or your preferred banking method while betting online abroad. If our information only gave a few results, then you may miss out on what is the best bookmaker for you, all things considered. Something may rank third, for instance, in your favourite sport, but still may be better for you than the top two options for other reasons. We always view our job as laying out everything we can for you to make informed decisions, and where and how you want to bet. With the benefit of variety, we can do exactly that.
5. It Was Fun!
While compiling these betting odds compare tables is a lot of hard work, it’s fun too. We’re sports fans through and through, meaning that whenever we can turn something into a competition, or in this case, several competitions, it’s something that we find interesting, especially as we have spent so much time and have so much respect for the bookmakers chosen for our betting odds comparison. We hope you get a lot of value out of this data, and we also hope you find the ongoing battle for odds supremacy as interesting as we do.
What About Betting Exchanges?
Betting exchanges are where you bet against other users of the site, as opposed to betting against the bookmaker. This means that the odds are, in part, dictated by the sway of demand between markets from players. A betting exchange does not make its money by relying on the overround (more on this shortly) and instead utilises a flat commission on winnings. Some people prefer this system to the usual route, and it certainly is an interesting twist on the typical betting market. If you want to learn more about betting exchanges in more detail, be sure to check out our article on the best betting exchange sites for more information.
Here, we are looking at betting odds comparisons from traditional sportsbooks. We include Betfair, but the odds are taken from their traditionally structured sportsbook. We felt that the difference in how both betting platforms work made it unfair for us to compare them side by side, and as most people go for the traditional option, we decided that sportsbooks were going to be our focus here. But that is not to say that betting exchanges are not able to provide tremendous odds value, and can definitely be the right choice for many people.
Can Promotions Improve My Odds?
All the examples we have used for our tables go from the base odds level to keep them as fair as we possibly can. But there are plenty of promotions that are capable of improving the value of your bet. And we don’t just mean by counting towards some kind of wagering requirements or providing some kind of cashback if you lose; although these, of course, do provide additional value in their own.
We are talking about things like bet boosts, boosted odds, price promises and best odds guaranteed promotions. Whether by directly increasing the value of your odds or by ensuring you get the best price, these directly improve your winning returns. This is worth taking into account when considering which bookmaker is best for you overall. A couple of great examples to help your understanding is our Best Odds Guaranteed promotions guide and our detailed William Hill Bet Boost article.
How to Check Out the Odds Quality Yourself
If you are interested in finding out about the quality of odds in general, there are two main ways of doing so. One is to check them against other bookmakers. This is what we do here, but of course, we can’t cover every potential market, so this is still worthwhile if you’re looking for something specific.
The way this works is you convert the odds into an implied probability percentage. We have a detailed betting odds article which helps to explain this while providing the tools you need to make the conversion.
If you do this with a set of odds on the same market, whichever has the lowest percentage is providing you with the best value, and will provide you with the biggest return. This can be tough to get your head around when you’re dealing with similar amounts, but consider it this way: if one team has a 5% chance of winning, and the other had an 85% chance of winning, a bet on the former to win would yield greater rewards.
If you want to check on the quality of your odds in a vacuum, you can do so by utilising the overround. If you have three possible outcomes, say, Team A winning, Team B winning and a draw, then all the odds when converted should come to 100%. That’s because 100% means certain, and one of these outcomes must logically occur.
However, when you do so they will inevitably come to over 100%. This amount above 100% is the overround or the bookmakers' margin – it is the edge the bookmaker has over the bettor. This is not unreasonable; it is how they remain profitable in a business, which is by nature hard to predict.
Still, there is a limit to what can be considered reasonable. We would say that anything below 110% can be considered reasonable, and the closer to 100%, the better. Do note that some markets, like esports, have higher odds than some more established markets, like football. You can also find out more about odds in general with our ultimate guide on betting odds.
Betting Odds Comparison FAQs
⚒️ How is your betting odds comparison calculated?
For each sport, we compare 15 different markets, note each time a bookmaker has the best odds and convert that into a winning percentage for each.
⚡️ Are the differences in odds even worth my consideration?
Yes, we certainly believe they are. They regularly produce a difference of between 1 and 2%, but often even more than that.
🤑 Why break the odds comparison down to different sports?
As you can hopefully tell from our odds comparison tables, bookmakers tend to have their strengths and weaknesses when it comes to different sports. This should help punters choose based on what sports are important to them.
🥇 Can promotions improve my odds?
Some promotions certainly can, such as bet boosts, best odds guaranteed, boosted odds and price promise promotions. Other promotions can also add additional value, but none that we are aware of directly influence odds.
ThePuntersPage Final Say
There is more to a good betting experience than odds quality. In fact, if there is only a small difference between bookmakers, you may still prefer the weaker alternative, especially if other promotions more than make up the difference.
With that said, we don’t think there is anything, perhaps with the exception of security, that is more important than the quality of the odds. After all, the bottom line is how much money you will receive if you win.
Importantly, the amount of variety out there means you should not need to compromise in any regard. Our goal – and the goal of this betting odds comparison – is to help you find the right betting site for you, with not only world-class odds but the right aesthetic, experience and focus that you are looking for. There is no need to settle for anything less.
