Testing is at the core of everything we do at OnlineSportsBetting. With so many online sportsbooks competing for attention, we believe the only way to separate the trustworthy from the unreliable is through real, hands-on evaluation. Our team of betting specialists brings nearly five decades of combined experience, having reviewed thousands of sportsbooks across the industry. This rigorous process ensures that when we publish our final list of recommended sportsbooks, you can sign up and bet with complete confidence.
Rigorous Testing Across 8 Essential Metrics
We dissect and analyze every key aspect of an online sportsbook across eight essential metrics:
- Bonuses: We audit terms and conditions and create mathematical models to assess total bonus EV. Using real bets, we directly test bonus payout speeds to uncover the most genuinely profitable rewards.
- User Experience: Our team of experts tests desktop, mobile, and app platforms on iOS and Android to find any issues. We look at ease of use and speed across devices.
- Security: We independently confirm licensing and regulation. Also, we audit encryption protocols and monitor risks using ethical hacking. We do thorough checks to ensure your funds stay protected.
- Odds & Markets: Our veteran analysts review odds for integrity and compare them to our projections to find the best values.
- Payments: We test all deposit and withdrawal methods to identify the fastest payout options.
- Support: Using anonymous accounts, we assess support rep knowledge on complex topics. Also, we directly test response times across email, chat, and phone.
- Promotions: We examine terms and conditions for reloads, parlay insurance, risk-free bets, and more. We uncover long-term value promotions.
- Registration: We directly test the signup process for speed, ease of use, and clarity on legal needs before reviewing each site.
- Other Aspects: We continuously evaluate many factors like website design, game selection, fees, app performance, and more. Our testing reveals the real user experience.

Vetting for Safety and Security
Hundreds of online sportsbooks fail to meet our security criteria. We blacklist any sites found to have:
- Abusive, scammy, and fraudulent bonus terms and conditions: We flag any sportsbook that uses misleading or unfair bonus rules, such as hidden rollover requirements or impossible wagering restrictions, designed to trap players instead of rewarding them.
- Excessively slow payout speeds or nonpayment of winnings: Any sportsbook that delays withdrawals beyond reasonable timeframes or refuses to pay out winnings is blacklisted to protect players from financial risk.
- Insufficient, questionable, or complete lack of licensing and regulation: We eliminate sportsbooks that operate without credible oversight or transparent licensing, as they fail to meet basic industry standards for fairness and accountability.
- Serious security problems, breaches, or other cybersecurity issues: Platforms with weak encryption, history of data breaches, or poor cybersecurity practices are deemed unsafe and removed from our recommendations.
This vetting process filters out the bad sportsbooks from our site. After this analysis, we only recommend entirely safe sportsbooks. We are an affiliate site, but we do not let this affect the final results of our recommendations. It is part of our affiliate disclosure statement to make sure we only recommend safe and trusted sites.
Ongoing Performance Audits and Monitoring
Our monitoring team constantly audits and tests even our favorite online sportsbooks for any changes, large or small. If we detect any issues, we immediately update our reviews accordingly. You can trust us to stay on top of performance problems!
Directly Testing Bonuses and Promotions
We don't just take posted bonus terms at face value. Our gambling experts will personally open and test signup bonuses and other promotions across multiple real money accounts. This way, we uncover issues and ensure the actual user experience matches ads.
Proactively Monitoring Community Feedback
We scour sports betting forums, Reddit, and blogs to stay on top of the latest user experiences at even top online sportsbooks. This gives us valuable early warnings if payout speeds slow or any other issues arise with a bookie. If you have any feedback or leads, please feel free to contact us.
