What Can You Expect to Find at an Online Bookmaker?

To the uninitiated, or anyone still relatively new to the concept of online gambling, the services offered by bookmakers online can be a little confusing. So to assist you in this regard, let’s take a look at what you are likely to encounter when signing up.

Sportsbooks

Most reputable bookmakers found online will offer sportsbooks, an industry term that refers to allowing customers to bet on a range of sporting events. Whether the sport in question is football, horse racing or basketball, punters get the chance to place all kinds of different wagers on the outcome of any sports event or match. When you encounter an online bookmaker worth their salt, you’ll typically find a wide selection of sports betting markets to enjoy. The best generally have a blend of many different international sports, including less well-known events like field hockey and netball. The most popular sportsbook services will also offer what’s known as ‘in play’ betting. This means that you can enjoy extra features such as making additional bets during the game and taking advantage of ‘cash out’ options that let you take your money and run before the event has finished. A high quality sportsbook will offer you lots of betting opportunities.

Casino Games

Whilst there are a few companies that focus solely on providing sportsbook services, the vast majority of top online bookmakers will also provide a full range of online casino features. Inside a typical online casino, you’ll find everything that you would normally see in a real-world bricks-and-mortar casino. You’ll see table games like blackjack, roulette, baccarat, craps and poker, which often involve live dealers, with players wagering against the house. Usually played on a green baize table, these games are the staple for casino fans across the world. Thanks to the internet, they can now be enjoyed whenever you want and wherever you are. Another popular type of game you’ll find at the best betting sites are online slots. The virtual versions of real-life mechanical slots are hugely popular thanks largely to eye-catching and exciting slot titles created by the many software providers that exist. A good casino will typically provide lots of choice when it comes to casino games.

Esports Betting

“What is Esports?” we hear you ask! Well, Esports is a relatively new part of online bookmaker services that centres around the playing of competitive video games. In an industry that’s worth billions, professional video game players compete in leagues and tournaments around the world, with millions watching online or on TV. Playing popular console titles like Call of Duty, League of Legends and Fortnite, professional Esport gamers face off against each other with bets being placed on the outcome. These bookmaker services are often accompanied with live streaming, allowing gaming fans to watch while they bet.

What Does Our Online Bookies Rating System Cover?

Our review team works hard to ensure that our readers get the information they need to make the best decisions about which online bookmakers they use. In this section, we look at precisely what it is that sets the best betting sites apart from the not-so-great operators. The truth is that there is a lot that goes into making a great online bookmaker experience, and our reviewers leave absolutely no stone unturned. Sit back and relax while we take you through some of the many factors that we assess.

Games/Betting Markets

One of the main things that our online bookie rating system looks at is how comprehensive the range and type of betting opportunities are. This combines the available selection of online casino games, esports and sportsbook betting markets that are on offer to the playing public. We also assess the quality of the casino games that are on offer. Any good bookmaker’s casino will feature titles from the most well known software providers, like NetEnt, Evolution Gaming and iSoftBet. Betting selection is a key factor in any online bookmaker experience, so in order to rate well with us, this has to be provided.

Bonuses & Promotions

In order to entice players and keep them loyal, the best online bookmakers provide a regular supply of incentives and promotions. The vast majority of bookmakers and casinos online will offer some kind of free money to bet with or free spins to use on their online slots. This can vary a lot between bookmakers, so those that are generous will rate well with our team. You can expect regular reload deposits, no-deposit bonuses and other incentives with top online bookmakers, so if your current online betting provider doesn’t offer this, it might be time to look for another one!

Wagering Requirements

Closely linked to bonuses and promotions is the aspect of wagering requirements. This basically refers to the amount of ‘playthrough’ that needs to be carried out in order to withdraw winnings gained through the use of bonus funds. This is usually expressed in 10x, 20x or 30x the amount that’s offered as part of the bonus or promotion. This means is that if you’re given a £50 welcome bonus with a 30x wagering requirement, you would have to wager £1,500 before you’re able to withdraw those winnings. The best betting sites that rate well with us will offer more reasonable wagering rules for their players.

Return to Player (RTP) Rates

Another important factor that our review team assesses is the rate at which each bookmaker’s online casino games pay out. The RTP rate refers to the amount that’s paid out in winnings versus the amount that’s been wagered. Whilst the house always has the edge, it does also need to be fair. Bookmakers that rate well with our reviewers will offer a reasonable RTP rate, which is typically worked out over an extended period.

Payment Methods

Top bookmakers will offer a wide selection of ways to deposit funds and withdraw winnings. Most often, you’ll find that Visa and Mastercard are accepted by bookmakers. However, in the modern day, there is now a wide selection of alternatives, like Skrill, Ecopayz, Neteller and many more. Certain types of payment options are preferred by certain types of online gamblers, so the best betting sites will cater to more of them. Payout speed is another associated metric that our reviewers look at when reviewing any online bookmaker.

Website Security

A safe place to wager on casino games and sportsbooks is the bare minimum any online gambler should expect. It’s something that the top online bookmakers offer, and any bookmaker needs to provide this security to rate well on our list. When it’s your money, your payment details and your personal info that’s at stake, it’s not hard to see why. One easy way to know if you are using an online bookmaker website you can trust is whether it displays a padlock sign next to the URL. If you see that padlock, it means that the provider is using a secure SSL encryption certification to keep your details safe.

Customer Support

When you run into a problem as a player with an online bookmaker, you need to know that assistance is available, regardless of the time of day. Online bookmakers that fare well with our review team will offer round-the-clock assistance across a variety of different channels. The customer support offered from bookmaker to bookmaker online can vary a lot, with some offering phone, email, live chat and sometimes even help via social media platforms like Whatsapp. No matter which methods are offered, responsive, speedy resolutions to account and technical issues should be provided.

A Mobile-Friendly Website

A top casino or sports betting experience rests heavily on how well the website in question operates across the variety of devices that people use to access the internet. People like to gamble on the move more these days, which is why any reputable online betting website needs to cater to this mobile audience. Whether a bookmaker chooses to offer a free downloadable app to access its services, or it opts for a mobile-optimised website, the experience needs to be largely the same on smartphone, tablet and laptop to rate well with our review team.

Ease of Registration

Joining up can be a pretty painless process, but there are some online bookmakers that really make you jump through hoops to sign up. Sure, there are reasons why it’s important to verify age, location and your eligibility to bet with certain websites, but you don’t want to be left waiting days to start playing. The best online betting website operators will make signing up nice and easy, with quick and responsive ID validation being provided. You really should be able to start playing the same day you apply, and the sites that rate well with us allow you to do just that.

We Evaluate - You Enjoy!

This is just some of the thorough process that’s used to assess each and every online website we review. We do this so that you can bet online with the confidence, knowing that you’re playing with the very best online bookmakers available.
