The fastest way to get a reputation is by building it and in doing that once a person gives you their trust you must try as much as possible to get them to have confidence in your services, and gambling site have a higher work to do when it comes to reputation since you have other casinos to compete with so you must operate in a way that makes impossible for your customers to have better services outside your casino.
A sportsbook does not achieve trust and reputation simply by what they advertise on media, on this forum or anywhere else. Their reputation will be made up of multiple factors.
- Transparent and clear Terms of Services & FAQs
- If they have restricted areas, they should mention it clearly in ToS.
- They should mention clearly about their policy on KYC, money laundering, multiple accounts, etc. because such things will be used to protect their casinos against cheaters or will be used as their deadly weapons to reject big withdrawals from users
It depends on different things and for different gamblers different things matter. First of all you need to work without problems and show good results in troubleshooting. Also you need a thread with feedback from the gamblers.
Promotion campaigns are sort of advertisement and can not be considered as what you can think of their trust level. A scam casino or exchange can run very attractive, well-paid campaigns but later they can make scam exit.
Not all things will be operated and proceeded smoothly all times. Sometimes, staffs on casino can make mistake and result in scam accusation against their casino. With such cases, if they are a good casino, they will go through in-depth investigation or even call for mediators to resolve their scam accusation. Mistake can be made but if you are ready to resolve it, you are all good.
