Which bookmaker is ideal for you?

To answer this question, you first need to ask yourself another: What am I looking for from a bookmaker? There are several answers to this question, including the best odds, the best welcome offer, the best customer support options, various payment methods, varied sportsbooks, premium app offerings, and many more.

You need to decide why you are betting, your reasons, and what you enjoy from a bookmaker. If you are struggling to decide, it is a good idea to make a strengths and weaknesses list for each bookmaker you are considering so you have a visual guide on what is available.

Also, do some digging and extra research into what certain bookmakers provide, as you may unearth something that changes your mind or cements your decision. For me, Bet365 has absolutely everything I need as I enjoy football, and they provide a wonderful service for this need. Think about what you want; there certainly isn’t a shortage of bookmakers to choose from!

Author’s pick; My favourite bookmaker and why?

What are the best betting sites I hear you ask. All things considered, and as aforementioned, Bet365 provides everything I need from an online bookmaker.

They offer a varied sportsbook and a great football offering with daily boosts and many markets to utilise, which is everything I need. William Hill also gets a special shoutout for their daily football-enhanced odds, but Bet365 is among the best betting sites.

Qualities that define an Industry-leading Bookmaker

What exactly makes an industry-leading online bookmaker? What do they need to have? Firstly, and most importantly, you need to be able to trust the bookmaker you are using. You will be depositing your own money into these sites and hopefully withdrawing too, but can you trust them to look after your money, or payout when requested? You should be looking for a fully regulated and licensed betting site. That’s the biggest thing you need to find.

Secondly, is there a varied selection of sports and betting markets available? There’s nothing worse than going through the rigmarole of signing up to a betting site just to find out that the sport you love isn’t available or you can’t bet on a certain market. This just takes a little research to find out exactly what a bookmaker offers before signing up.

Another quality an industry-leading bookmaker should have is regular promotions. It doesn’t really matter what this looks like, as long as they are offering daily enhanced boosts, special offers for major events, or competitive odds, you know they are serious and have you at the forefront of their operation. It is all about engagement and feeling a part of something, and something as simple as boosting the odds of a selection can engage bettors.

Furthermore, a responsive customer support system is another must-have quality. If you need immediate help or a quick response and there is nothing there to give you this required help, chances are you will be annoyed and won’t want to use their services again. It also shows customers that you care about them, which is important.

Lastly, an important feature is a variety of payment options. This is key as the more payment methods that are available, the more people can use the site. It is all about access. Also, various payment options usually indicate a bookmaker's safety.

These factors all contribute to making the best betting sites what they are and why they are industry leaders as they all have these features at the very least.
