What Makes the Best Online Bookie Bonus Offers

Most bookies bonus offers will include some form of added value. In most cases, sign up bonus offers for new customers will often be in the form of free bets worth 100 – 200% of a set amount bet. For example new customers placing a £20 bet at Titan will receive £30 in free bets. Which basically means matching the amount of the initial bet at 150% value. Similarly Betsafe offers players 200% return yet this is capped at £10. At the end of the day it is about finding the right bonus for your betting intentions. Online Betting offers will often be advertised as “Bet 5 get 20” or “Bet 10 Get 30”, but things are rarely as simple, the chart above represents our experience in testing these online betting promotions and seeing which ones are actually likely to yield the best value.

Matched Betting Bonus Offers

Bookies will normally match first deposits for new customers in ranges between 50% and 300% of the first bet or deposit made and in sums of up to £200. These bonuses and offers will generally carry some requirements in order to earn the free bets or cash match. Clearing the bonus for use will require that punters roll over the deposit amount a certain number of times (from as low as once to as high as eight times) and at minimal odds that usually are around 1.5, we have taken the requirements into consideration and the matched betting offers at the top of our table are fairly easy to clear, to a degree that most bettors will only need the first deposit if applied cleverly.

Check the terms and plan ahead in order to make the most of your matched betting offer.

This bookie offer is also known as “match betting”.

Understanding Betting Offers Terms and Conditions

The terms and conditions (T&C) from online bookies are not like what you might be used to if the only T&C you have ever looked at are those from Microsoft or Apple. For example the terms of the aforementioned Titan bonus are pretty straightforward and indicative of the kind of terms you will see at most reputable bookmaker sites. These include:

And a couple of other lines stipulating that it must be a new customer and no fraud is involved.

In layman terms what this means is that if you are a new customer, all you need to do for £20 in free bets is deposit £30, bet it on odds of 1.75 or higher and use the free bet tokens by the seven day deadline. Pretty simple and straight forward. If you see over complicated T&C’s that means that the site is trying to minimize the likelihood of punters actually enjoying the bonus and would generally be a negative indicator for the bookmaker as a whole.

Optimizing Value from New Customer Betting Offers

Once you have signed up with a new account to a betting site it is important to make good use of the welcome offer from your new bookie. First deposit offers are often the best per-money proposition a betting site will give out.

Make sure you read the terms and conditions associated with the given bonus, usually there is a requirement for minimum odds and wagering amounts. Make sure your first bets are close to the minimum odds and plan ahead to hit the wagering requirement. This will assure you unlock the bonus amount while making the most prudent bets in the process.

Best New Customers Offers At Online Betting Sites

The best deals at online bookmakers are usually found at “online only” betting sites. The specific best bonus for each online bettor depends on several factors:

  1. Deposit Amount
  2. Type of Bets
  3. Markets You Intends to Bet
  4. Place – Your location
  5. Personal Preference – When it comes to usability and navigation
  6. Additional Factors varying from streaming options, payment method options and a few other issues.

Overall, we recommend online bettors try several of the high profile bookies, enjoy the added value from welcome bonuses and pick a favourite while occasionally using the other ones for specials or enhanced odds.

Betting Sites and Their Promotions

Online bookies enjoy a variety of advantages over their high-street competitors. Beyond the obvious of no rent and upkeep and no direct employee costs, they can also offer a lot more in terms of quality deals. Online bookies are always running a wide selection of promotional offers, intended to entice all sectors of their client base, and the smart punter will do well to recognize the ones which are relevant to the bets he or she intends to make.

Most big football matches will feature price boosts, televised horse racing events will be accompanied by a “no runner no bet” promo, and the list goes on. When you have a bet in mind be sure to check if any relevant promotion is available first and consider adjusting your strategy accordingly. Betting app offers are also a regular feature of online bookie promotions and many will offer an extra tenner or so as a reward for trying out the mobile betting app.

The Bottom Line on Bonuses and Offers

The bonuses and promotional offers from online bookies are not going to make you rich or magically make cash appear but can provide some solid value for new customers and existing ones alike. When signing up at a new sports betting site there is at times a sense of unfamiliarity and the free bets or enhanced odds are a positive way to get over this initial phase. You would be wise to give a new bookie a chance, especially with added value opportunities at hand. Best Bonus Bet Offers! Sports Betting Sign-Up Offers!
