What are Betting Bonuses?

So, what are betting bonuses? Well, some people like to see betting bonuses as ‘free cash’. We do not see it like that. We like to see betting bonuses as a little bit of a sweetener to sign up to a site. Just a ‘bonus’ bit of cash (that you won’t be able to withdraw) to get more of a feel for the way the site works. For online betting sites, the betting bonuses are designed as a bit of a marketing exercise. They are a way to attract people to a site and, of course, since every other site is seemingly offering betting bonuses, you have to do so too.

New Gambling Sites Often Have the Best Betting Offers

In our experience, it tends to be the newer betting sites that offer the best betting bonuses. This makes sense. After all, bookmakers rely heavily on their reputation in this business. If you are new to the industry, you don’t really have a reputation that you can utilise to pull in people to gamble with you. This means that you do need to find other ways in which you can stand out. Offering better than normal bonuses is probably the best route to go down here.

Tip: Always Read the Terms & Conditions

We do want to point out that before you take advantage of any betting bonuses, you should always read the terms and conditions related to that bonus. We know that it is going to be rather bland to do that, but the information that you find is going to be vital. It will tell you what you can and can’t do with your bonus. It will talk about wagering terms, that sort of thing.

The wagering terms are probably going to be the most important thing for you to pay attention to when it comes to betting bonuses. A lot of people think that if they win, they can just walk away with their winnings without a care in the world. Generally speaking, this is not the case. You may need to play through your winnings several times before you can withdraw anything. Of course, the whole idea of this is to reduce the chance of the bookmaker needing to give away a bit of free cash. In other cases, you may also need to remember that you may not be able to bet on certain events at certain odds. This, once again, is to ensure the risk of the bookmaker having to give you money is reduced.

All of this is detailed on your terms and conditions, so we cannot stress just how important it is you read through them. You may be told some of this information in passing, normally with a little * next to the bonus, but go through and read everything. It will make sure that your life is full of far, far fewer surprises.

Welcome Bonuses at Sports Betting Sites

These are the most common bonuses that you will see, although that is mostly because you won’t get to see the other type of bonus until you have signed up to the website, and you aren’t going to sign up to every site, are you? Your welcome betting bonuses can take many forms including:

  • Extra special odds on certain events. This means crazy good odds.
  • Free bets
  • Matched deposits (although, this may only be for a couple of quid, not the massive bonuses casinos tend to offer)

Companies do like to mix and match what they offer on occasion. A lot of the time, you will find that the best welcome bonuses will appear at the times of the year when there are major events going on. So, always check out a new betting site at that point if you want to take advantage of welcome bonuses.

Loyalty Bonuses & Promotional Offers

Your loyalty bonuses are going to take pretty much the same form as the welcome bonuses. However, of course, you will need to be signed up to enjoy them. From time to time, you may be introduced to a few special offers from the betting company that you can sink your teeth into. 

These will often be tailored to the types of games you have been playing at a site, so they are certainly going to be worth checking out. You will find a lot of the best loyalty bonuses will come during the low points of the year. This is because these sites want to keep people gambling and, as a result, will want to try and pull people in any way possible. Loyalty bonuses are one of the best ways for them to accomplish this.
