To be frank, many campaign done on here for shorter period of time always come back later for continuation because they knew been here consistently brings better results, I won't mention the names of casino though. Bringing brands here for promotions has always been a positive one but don't expect the results immediately.
Interacting with the community events, contest and many other leaderboard activities will certainly make this brand a chosen one in the forum.
The brand should see everything from a player's perspective to understand how they are doing. As a player, I won't jump and join a casino that I am seeing for the first time. Of course, I have to check how long they are here. If they are spending money on marketing, I can understand that they are going to run a serious business. It is also important to have an active casino representative here.
I won't join a casino if it doesn't have an active representative. People usually expect special treatment from the casino representative, which develops an extra layer of confidence.
