How We Review & Rate Betting Sites
With so many online betting options that vary by location, the average bettor doesn't always have the time to test every site to find the ones that suit them best.
At Gambling.com, this is our job. We test betting sites ourselves so you don't have to, incorporating user feedback from our community. We follow a rigorous hands-on review and rating system.
Combining expert research with user insights, we confidently rank the best betting sites and explain why they stand out. This allows us to recommend legitimate online betting sites that deliver.
Our 10-Step Testing Process
Our expert reviewers evaluate each betting site using a strict 10-step process.
- Verify Licensing & Security: We check to ensure the local gambling authority in your area licenses the site and that it is safe to use. We only recommend using legal and licensed betting sites.
- Register & Verify ID: We sign up for each betting site and complete full identity verification.
- Deposit Real Money: We fund the betting account using popular payment methods.
- Claim Welcome Offer: We claim the sign-up offer and evaluate the fairness of the terms and conditions and the overall value of the bonus.
- Assess Odds & Markets: We compare odds value and review the variety of sports and markets that can be bet on.
- Test Ongoing Promotions: We claim offers for existing customers, assess their value, and analyse their terms and conditions.
- Place Real Bets: We test different bet types across various sports and markets, including pre-event, in-play, and outright bets.
- Contact Customer Support: We evaluate the speed and helpfulness of customer support.
- Test Across Devices: We assess a site or app's overall performance using iOS, Android, and desktop platforms.
- Withdraw Funds: We confirm withdrawal options and measure processing times.
This process allows us to compile in-depth reviews on each betting site and ultimately assign each site a Gambling.com rating.
Gambling.com Ratings for Betting Sites
Following our 10-step testing process, we score a betting site out of 10 in each category. Each of these key performance indicators is weighted equally.
- Sports & Markets: Our top betting sites have diverse, deep betting markets.
- Promotions or Betting Features & Tools: We evaluate the value and fairness of welcome bonuses and ongoing offers. The best betting sites have promotions and loyalty programs that consistently reward bettors. (For jurisdictions with restrictions on when and how operators can offer promotions, we grade betting features and tools instead.)
- Payments: A betting site should have a variety of payment methods that move quickly while keeping your data safe.
- Customer Support: We contact customer support channels to ensure agents are responsive and knowledgeable when helping users.
- Reputation & User Feedback: We consider real user data from conducting focus groups, live testing, and reading online reviews.
- Site User Experience: A betting site with user-friendly designs should be easy to navigate.
- Mobile Product Features: We download and test betting apps on multiple devices to ensure mobile performance and features work as intended.
- Responsible Gambling: These tools should be practical and easy to find for bettors of any experience level.
- In-Play Betting & Live Streaming: We evaluate the quality of live betting markets and live streaming capabilities. Betting sites should be able to update in real time, allowing bettors to react to ongoing action. (In jurisdictions where in-play or live betting is restricted, we only consider live streaming.)
- Odds Value: We evaluate the competitiveness of odds across the market, including how quickly odds are posted and updated.
We then average these scores to create a final Gambling.com Rating; for example, 87 points results in an 8.7/10 rating.
We carry out a full re-evaluation every six months to ensure our reviews remain fresh, fair, and up to date.
User Feedback
At Gambling.com, we don’t just rely on our in-house experts; we listen to the opinions of the average punter.
Your feedback plays a vital role in shaping our betting site reviews, ensuring they reflect what actually matters when placing a bet.
Here’s how we gather user insights:
- Live User Testing: One-on-one sessions with real bettors navigating sites in real-time, captured by moderators for unbiased insight.
- Focus Groups: Deep-dive discussions with users exploring everything from navigation to payout speed.
- User Ratings & Reviews: Members rate and review their betting experiences, highlighting positives and negatives.
- Surveys & Polls: Quick questions to our community about new features, bonuses, and site updates.

How We Keep Our Rankings Updated—And Keep You Informed
Our rankings are never set in stone. We review them at least once a month, often more frequently when warranted, and reevaluate them every six months. When promising new betting sites launch and deserve recognition, we reassess the entire list to make room.
Likewise, we reward progress. If our testing shows that an existing site has significantly improved its platform, it can earn a place on the list.
We also routinely revisit every betting site that is already featured. Our in-depth reviews are rewritten based on fresh data and current performance.
In short, we continuously monitor the betting landscape to ensure our rankings are always current, fair, and merit-based.
Why Trust Gambling.com?
Since 2006, we’ve tested and reviewed over 3,000 online betting sites for our readers worldwide, only recommending the best licensed options. Our global workforce of more than 600 professionals includes avid bettors and experienced gambling industry experts.
Gambling.com has been recognized by several international betting organizations, including:
- North American Sports Affiliate of the Year at the SBC Awards in 2025
- eGaming Review’s Affiliate of the Year award in 2018 and 2021
- eGaming Review’s Employer of the Year in 2024
Gambling.com has also hosted the American Gambling Awards since 2019, honoring the best companies, organizations, and individuals in the regulated U.S. market.
We consider user feedback essential to comparing and ranking betting sites, ensuring that real insights shape our recommendations.
We do not recommend offshore or blacklisted betting sites, as no governing body has licensed them or ensured the safeguards necessary to protect bettors.

Shannon Lane

"I care about how easy (and fun) it is to use a sportsbook. It’s not just about navigation and withdrawals (though those are important); it’s also about unique features, data, and meaningful loyalty benefits that can give you a complete experience as a sports fan and bettor."
Cathal Austin
With over a decade of reporting experience for major publications in Ireland, Cathal brings a reporter’s research skills to every review he writes. He knows what matters most to bettors—valuable odds, lots of betting options, and promotions that deliver real value.
“I dig into the details and tell it straight - so people know which betting sites they can trust.”

"Speed and ease of use are non-negotiable - if a site lags, crashes, or takes too long to load, I’m gone. I want to place a bet easily, especially in-play bets where every second matters."
Peter Mooney

"As a bettor, I pay close attention to how sportsbooks price their markets. I care about the value that my fellow bettors and I are getting. A sportsbook doesn’t have to be flashy to get my attention, but it needs to work well for the user."

Why You Should Choose an Online Betting Site
Online betting sites offer several advantages you can't find in a physical sportsbook or betting shop:
Competitive odds
Top platforms consistently provide strong odds across various sports and racing markets, often surpassing what traditional outlets offer. This translates to better long-term value for your bets. Many also feature odds boosts, which increase your potential winnings without requiring a higher stake, and reduced juice. Plus, you can shop around for the best odds across multiple sites.
Extensive market coverage
Online betting sites provide an unmatched variety of sports and betting markets, all at your fingertips. With the click of a button in a matter of minutes, you can bet on virtually anything.
Promotional offers
Betting sites frequently offer welcome bonuses to new users and other promotions to ongoing users. Rarely will you see a brick-and-mortar sportsbook offer discounts or specials.
Seamless betting on the go
Top betting sites offer fast, reliable mobile apps that make it easy to place bets, find markets, and manage your account on the go. You're not tied to a physical location, so you can easily fit betting into your routine.
Flexible payments
You'll find many secure payment options to deposit into or withdraw from your online banking accounts. You don't have to stand in line to wait for cash after you win.
Cutting-edge technology
Modern betting sites combine your favorite user features, like live streaming and personalized home feeds, found across the internet. Online sites go the extra mile by cashing out your bets early, allowing you to craft custom bets, and live betting.
Responsible Gambling with Licensed Betting Sites
Betting should be fun, never a source of stress or financial pressure.
Here are some smart, practical ways to help you stay in control:
- Set a Budget: Choose a weekly or monthly limit that suits your finances and stick to it, win or lose.
- Accept Losses: Losing is part of betting. Avoid chasing losses or making emotional, high-risk decisions.
- Use Built-in Tools: Use deposit limits, loss caps, timeouts, self-exclusion, and reality checks.
- Know Where to Get Help: If gambling starts to feel harmful, reach out 24/7 to free, confidential support services like the National Council on Problem Gambling, GambleAware, GamCare, Responsible Gambling Council, International Center for Responsible Gaming, Gamblers Anonymous, or GAMSTOP.
