How to choose the best betting websites

Before diving into the action, you have to make thorough research regarding every aspect of the bookmakers. We present to you 10 main factors needed to take under consideration before you start to play at the sportsbook you choose. here you can find some tips on how to make the correct choice and play at the best bookmaker.

  Betting odds on all marketsBetting odds on all markets

You might believe it is enough if a bookmaker offers a 96-97% payout just on the W-D-W market. Well, guess again, it isn’t/ The best bet sites are the ones offering odds that are competitive, this means more than 94% on all markets, like over/under and both teams to score and not only 1-X-2.

Live Betting with live StreamingLive Betting with live Streaming

Live betting is very appreciated and it seems to be the future of sports betting. A demanding player shouldn’t settle only for competitive odds, although it’s important to have a payout of 94% or more, like we said before. You should still look for specific features to be available. Live streaming is essential for all bettors, but the live events offered by bookmakers differ from one to another. So check that as well. 

Quickbet is an important tool for placing your bets instantly and without delays, while multiview should give you the chance and space to monitor at least 4 events at the same time. Bet acceptance should be in 5 seconds or less.

Bookmakers offering Cash Out with High payoutBookmakers offering Cash Out with High payout

Cash out has been the best tool for players. It’s evolution is ample and along with classic cash out, the partial and automatic came to the spotlight. If the bookmaker offers all of them, it is a huge plus for betting sites and players as well. The bigger the return, the better. So if you are an experienced player, you should check the payout of the cash-out, which usually should range from 91% to 95%, depending on the market. It is also important that this feature is open and available until the late stages of the game for multiple and single bets as well.

Better and fair promotionsBetter and fair promotions

A good welcome bonus is always…well good, but the personalized promos and daily offers give extra points to bookmakers.  Reload bonuses, free bets, enhanced odds or accumulator boosts shouldn’t be missing from your bookmaker. 

Then we have the matter of percentage of the promotion. It’s not the same to have a 100% up to 100 euros reload bonus rather than 25% up to 200 euro. Better offer also means more relaxed rollover conditions, like wagering amount, deposit method, markets excluded or minimum odds. Of course, a good bookmaker must have a loyalty program, this shows that the betting site offers rewards to players activity not just on the losses.

Range of markets and leagues

Beside quality, quantity matters as well. Most of the top betting sites offer an average of 40.000 events/month. 1000 live matches daily, 100+ extra markets and 30+ sports. There are some brands with low 10-15 sports and 5-20 alternative markets. Don’t go for that.

Mobile site and appsMobile site and apps

Betting on the go is the future and it’s becoming an important feature for the player. It is very important for the bookmaker to offer native mobile apps for Android/iOS devices. But pay attention, the app must be light , not more than 40 MB, or else you will encounter problems with loading times. Also, be sure to check the data required for the app or mobile site. The fewer than MB, the better for you.  If the bookmaker doesn’t offer an app, then it’s necessary to offer a good mobile site. No matter the platform they choose to offer, app or mobile site, anything more than 5 steps to place your bet, or 3 for live betting indicates a weak construction of the app or mobile site.

Features offered for enhancing your betting experience 

The structure of the site, colours and general appearance must be good, but the difference is made by extra features that the bookmaker is offering to players. Characteristics like Asian View, Smart search-which helps you find the team or the match you need or a system calculator for calculating your bets. Those give a great boost to user experience. Same things apply to Bet Builder though you have the possibility to build different bets from a single match. Edit my bet gives you the choice to modify the bet at will and at any time.

24_7 Customer Support24/7 Customer Support

True, it is very important to have 24/7 customer support, but it’s not enough to be a good bookmaker. The agents should be fast in giving expertized answers-this should not take more than 1-2 minutes. You can always feel when they give predefined answers or they don’t seem able to solve your queries.  Of course, the more channels for contact they offer, the better. Email, social media, skype, viber, telegram, Live chat call back or phone calls are the most common ones. If the bookmakers offer multiple markets, they should have multilingual Customer support.

Payment methods and free transactions bookmakersPayment methods and free transactions

Ok, when you put money in your betting account, you should not be charged, so we appreciate bookmakers that have no fees for depositing. Standard payment methods can’t miss from the bookmaker (cards, e-wallets, bank transfers). We appreciate brands that offer local choices as well-it will be much easier for you  to make a deposit if a sportsbook offers local alternatives.

The withdrawal times per type should not be longer than 24 hours for e-wallets and up to 3 days for cards and bank transfer.

Best international betting sites - Which are they?

Players from each country have different needs when it comes to online betting. Apart from the quality of sportsbooks , the localization is also very important for every territory’s bookmaker rankings.  In the list below, you can find the best bookmakers by country, it is also a good way to check if a specific bookie accepts players from your country.

We presented already and analyzed the most obvious and crucial  factors. Also you have an analysis of what makes a betting product really good. You can use those to pick the best bookie for you. We aim to go even deeper and point out some hidden factors for you. 

These are very important because it determines if the bookmaker has a reliable company behind and trustworthiness.

Top betting sites - How do we rank them

If you already chose the next bookmaker to play at, hold on a minute, this might change your mind because there are more to look out for before you know what good online betting sites mean. Our team has made extensive digging regarding every bookmaker when it comes to in depth info. Keep reading to see what your eyes should be on.

License and Legit bookmakers License and Legit

These are two factors. What makes a site legit? And how can you measure the trustworthiness of a betting site? Well, the bookmaker should have responsible gambling policies, and must have the intention of protecting the players. Also privacy policy is very important and a big issue if the online bookmaker doesn’t respect it. 

This means that if you as a player choose not to receive a newsletter it is wrong to be bombarded with promotional messages.

Licensing is crucial, very important and a must, otherwise you should ignore the bookmaker at once. The best and trustworthy sites should hold a license from a good and big regulator, like UKGC or MGA, or at least from domestic authorities like Arjel in France and AAMS in Italy.

But keep in mind that this doesn’t mean that all sportsbooks with Curacao license are bad or not fair. In fact, we have seen brands with Curacao licenses that are fairer than some with MGA licenses. Of course, because the Curacao license is cheaper 25-30k, it attracts more scammers.

Dispute Policy is another criteria that shows a site’s trustworthiness. In case of a dispute you might have, you can address your complaints to IBAS (for UKGC license holders). This is not the case when an offshore bookmaker is involved. Also it is of big importance that the betting site is certified from 3rd party labs like iTech Labs or GLI, both of them guarantee that the games are fair and the platform is compliant and tested.

Experience means reliabilityExperience means reliability

Bookmakers and betting sites are like wine, the more years in the business the more established and trustful will be. Also, if it’s old it gives us the opportunity to monitor the site and see the positive and negative track record. Interwetten is a good example. They were established in 1990 and complaints filed against them are minor.

Most popular betting sites traffic is a good indication on how other players see the bookmaker. Bwin for example has 20 millions clients, can’t be all wrong.

Best betting websites stability and popularity bookmakerBest betting websites stability and popularity

There are different internet betting sites around, not all of them can guarantee safety and reliability. We have privately owned companies and not all of them can promise stability. Then we have the companies which are listed in the stock market. Betsson for example which is listed in Nasdaq Stockholm. They know that people complaining about their products shares will be affected so they go by the book following the procedures. 

Also, we have groups created by iGaming experts like Kindred Group (they own Unibet, 32Red), GVC Holdings (Bwin,Sportingbet) and Stars Group ( Pokerstars, Betstars). These names demand respect and are synonyms with security for the players.

Scam bet sites and players complaintsScam bet sites and players complaints

We always search the internet to uncover complaints about bookmakers, we search forums and sites but not all can be trusted. There are some like AskGamblers or SBR which can give you a sense of direction but you still have to be careful. Both of them can have fake profiles created by the bookmakers who target them to manipulate you. That is the reason we created our telegram group, where we can all discuss bookmakers from our site.

In many disputes it was proved that the operators were right. So, if 20 players out of thousands are unsatisfied, doesn’t mean that we have a scam bookmaker, usually those people are bonus abusers and don’t meet the requirements for rollover. So they will be banned sooner or later or the bookmaker will impose betting limits. So they will try to bring the bookmaker down. Of course, we have serious complaints as well. 

From 100 players reviews, there are 90% complaints, and the reasons may vary from case to case. We have seen complaints about wagering limitations or financial issues. 

Of course, remember to join our telegram group and we can discuss there all the issues may occur, also we will assist you in every need you have.

Transaction policies and fair T&C’s

Clear terms and conditions are very important for us and for the players, so you should check for that before you start to bet. We have seen some terms and conditions which showed the clear intention of the bookmaker to turn the tides towards them.

«We may, at our discretion, allow usage of the Duplicate Account to be deemed valid and in this case, all losses and stakes placed by or for you through the Duplicate Account shall be retained by usor « We reserve the right to close your account at any time for any reason and without having to justify our decision to you» – this shows that the bookmaker wants to turn everything in their favor.

You should always make sure that the operator has good intentions and it’s fair with players. Always take a look at their terms and conditions to find loopholes turning the tides in their favor. Also, if a sportsbook imposes limits on regular occasions, it’s not a good sign. We have seen brands who cut the odds off in the middle, or a betting limit to 1 euro/dollar has been imposed during bonus wagering. Plus, always check the withdrawal policies to be fair and clear. If you made a deposit via Neteller, then you should have the possibility to make a withdrawal via Neteller as well. Check the policies to be aware of bad terms, like pending withdrawals for 5 days or more just to make you lose your gaining’s.

Which is the best online betting site for you?

There are some factors that are important at first sight. Responsiveness of the platform, desktop and mobile compatibility, design of the website, variety of markets and sports selection, promotions and many more features that might convince you to choose a bookmaker. All of them make the difference between a good bet website and a bad one. But those are just the tip of the iceberg, or a drop of water in the desert. Never try to adapt your betting needs to what a sportsbook or a bookmaker offers to you. The User experience is something different which you should dictate, not the bookmaker. Don’t be afraid to change the bookmaker if you are not satisfied with them, doesn’t suit your needs or express your betting style.

Remember, your money, your rules! Even if you are a pro player, high roller or a recreational bettor.

You should check the limits in terms of wagering and depositing/withdrawing or the winning limits no matter from which category of player you are a part of. If you are a pro player, you should not place your bets on a sportsbook that targets recreational bettors. They offer different things. In exchange, you should focus on a broker, betting exchange site or arbitrage friendly bookmaker. Same goes for the Asian handicap players, choose a bookmaker who offers those for you. If you want to be incognito or under the radar, choose a crypto sportsbook.  

If you bet because it’s fun and you are a recreational bettor then go for a bookie that suits your needs. Never adapt! In this case
