What is our Bookmaker Review Process

Our goal is to provide you with thorough, reliable, and unbiased reviews, ensuring you can make informed decisions when choosing a betting company. Our meticulous review process covers key areas such as promotions and bonus offers, odds and markets, payment methods, customer service, and license and security. Here’s an in-depth look at how we gather information, generate scores for each category, and compile a total score. 

Promotions and Bonus Offers logo

Promotions and Bonus Offers

Sources: We thoroughly review the betting company's official website to examine their promotions and bonus offers. Additionally, we consider user testimonials and industry reports for a broader perspective. 

Verification: We cross-check the terms and conditions of each promotion, focusing on wagering requirements, expiration dates, and any restrictions to ensure they are fair and transparent. 

Criteria: Our evaluation criteria include the variety and generosity of promotions, the fairness of their terms, and their accessibility to both new and existing users. 

Score Generation: Points are assigned based on the competitiveness and user-friendliness of the offers. Higher scores are awarded to companies with attractive, fair, and easy-to-understand promotions. 

Odds and Markets  logo

Odds and Markets

Sources: We analyse the betting company’s odds across various sports and markets. By comparing these odds with industry averages and those offered by competitors, we ensure our assessments are accurate. 

Verification: We utilize statistical tools to ensure the odds provided are both accurate and consistent over time. 

Criteria: We evaluate the competitiveness of odds, the range of available markets, and the inclusion of niche sports. 

Score Generation: Our scoring is based on the margin (profit the bookmaker takes), market depth, and the diversity of betting options. Companies with lower margins and a wide range of markets score higher. 

Payment Methods  logo

Payment Methods

Sources: We examine the payment options listed on the company’s website and consult user reviews regarding their transaction experiences. 

Verification: We test the deposit and withdrawal processes ourselves to assess processing times, ease of use, and any associated fees. 

Criteria: We look at the variety of payment methods offered, the speed of transactions, and the costs involved. 

Score Generation: Companies are rated on convenience, reliability, and cost-effectiveness of their payment methods. Those offering fast, low-cost, and diverse payment options receive higher scores. 

Customer Service  logo

Customer Service

Sources: We engage with the company's customer support through various channels including live chat, email, and phone to gauge their service quality. 

Verification: We assess the response time, professionalism, and effectiveness in resolving issues through direct interaction. 

Criteria: Our criteria include availability of support, response time, and the quality of the solutions provided. 

Score Generation: Higher scores are given to companies with 24/7 support, quick response times, and high customer satisfaction rates. 

License and Security  logo

License and Security

Sources: We verify the company’s licensing information from reputable regulatory bodies and review security certificates from third-party audits. 

Verification: We ensure that licenses are current and valid, and that security measures such as SSL encryption and data protection policies are in place. 

Criteria: We evaluate the reputation of the licensing jurisdiction, the robustness of security protocols, and the transparency of their operations. 

Score Generation: Companies with strong regulatory compliance, comprehensive safety features, and clear transparency score higher. 

Total Score Generation  logo

Methodology 

  • Weighting: Each category is assigned a weight based on its importance to the overall user experience. While this does mean that certain categories are more important, our score generation algorithm creates a fair test and the algorithm is consistent across all reviews. 
  • Aggregation: We combine scores from each category to generate an overall rating. This balanced approach ensures that the final score reflects the overall quality and reliability of the betting company.

FAQs

How fast do bookmakers payout?

Payout speeds vary by payment method. As a rule, eWallets typically process within 24 hours, while credit/debit cards and bank transfers may take 2-5 business days. Some bookmakers offer instant or same-day payouts for select methods.

How do you know if a gambling site is legit?

Check for a valid licence from reputable authorities, such as the UK Gambling Commission. Look for SSL encryption, positive user reviews, transparent terms, and responsive customer support to ensure the site's legitimacy.

What percentage do bookmakers get?

Bookmakers typically take a margin, or ‘vig’, ranging from 5% to 10%. For highly competitive markets, this margin can be as low as 2% to 5%, ensuring they make a profit regardless of the event's outcome.

How do bookmakers make money?

Bookmakers make money by setting odds with a built-in profit margin, balancing bets on all outcomes, and ensuring the total percentage exceeds 100% (overround). Higher bet volumes with small margins lead to significant profits.
