Online betting has grown enormously over the past couple of decades and during that time the landscape has evolved significantly. More and more punters are betting on mobile or tablet and this has resulted in ever-more efficient apps being offered by the leading betting sites. Not only that but bonus offers have become more competitive and there is arguably more value to be had when joining an online betting site than ever before. This is certainly excellent news for the punter as it provides them with a chance to get things off to the best possible start when joining a new betting operator.

All of our featured betting sites offer a sign-up bonus offer of some sort. These are all simple to claim and all that is required is that you make an initial deposit and place a first bet. The amounts required are relatively small and in most cases you will receive a ‘welcome bonus’ which in betting terms is worth far more than the initial outlay.

Once you have made a deposit, placed a first bet and had your wager settled (either win or lose), you will receive a welcome bonus, provided that you have met all the criteria as defined in the terms and conditions (always read the full terms and conditions carefully as they differ significantly between betting sites).

Free bets and other bonuses are also offered to existing customers as a way of reading them for their custom. As a general rule, the more you play the more you can claim in bonus funds. These bonuses come in many forms such as cash-back offers, free bets, enhanced prices, etc. They can be used on numerous markets and sports – again subject to terms and conditions.

Each bookmaker operates independently of each other and as such, you can freely take advantage of as many sign-up offers as you wish, provided you haven’t already registered with the same bookmaker in the past and claimed the welcome bonus at an earlier date. Also it must be remembered that you will need to make a deposit and place a first bet in order to release each sign-up bonus, while you cannot simply cash the free bets in, they must be used to place actual bets and may be subject to wagering requirements.

The sign-up bonus isn’t the only thing to consider when choosing a betting site. It is important to consider the range of betting markets and whether or not your preferred sport or sporting events are covered. The competitiveness of the odds on offer is also hugely important and you can find details of these in our bookmaker reviews. Read these fully and check out the terms and conditions attached to each welcome offer. The best betting sites will all offer a multitude of sports betting markets and most operators will feature the likes of football and horse racing prominently on their sites.

The number of football markets can vary greatly between betting sites, however the larger operators can offer up to 300 markets for some of larger football matches in the big leagues such as the Premier League, Bundesliga, La Liga, Serie A and Champions League. The World Cup and European Championships also attract a huge number of bets and the best betting sites cater for these with a vast range now betting options and some competitive odds.

 

Which Betting Sites offer the Best Odds?

Competition is fierce amongst the best betting sites and all of the larger operators offer hugely competitive odds across their markets. Nevertheless, some leading betting operators focus on particular sports and betting markets and it does pay to shop around for the best prices on your chosen sports event. Some bookmakers will offer the best odds on football, while others may be at the top of their game when it comes to horse racing odds. Indeed, there is no one betting site that consistently offer the best prices right across the board, they all have their own areas.
