That applies to casinos that come to the forum or they want to market here, like Op is the way, it goes according to what should be done in marketing on the Bitcointalk forum, then holding a signature campaign is a way to get more exposure from gamblers in this community, if only making ANN then it will be quite difficult to get famous.
Hiring streamers or even influencers is a pretty good thing in marketing, it will help our products be recognized by many people faster, and such methods are often used by casinos or gambling platforms that are already large in expanding their consumers, of course, at a cost that is not cheap, because hiring people needs to pay quite a lot.
I have a suggestion not to focus on this forum alone, which suggests that social media also needs to be looted to get more consumers, such as X, YouTube, FB and others that allow gambling advertisements on their platforms.
We can see many new casinos comes to this forum and promoting their site so they can gets popular and have reputable among the other casino. Many new casinos succeeded their plan to promote their casino site in this forum so that still a good way to use the same strategy.
The casino owner must have different ways to promote his casino and not just use signature campaign. Many other promotion types they can use to have more customers visits on their casino site. The casino owners must calculate how much budget he can prepare to promotes his site and always check the result in monthly. By doing that, he will see how good the progress of the promotion so he can try to use the other promotion method is that necessary. If he can doing a good works, he will see the profit will comes to his casino.
The same strategy is indeed quite effective here, because that is how they work well, some other things are also done such as Sportsbet.io, Roobet, Stake and others have their own unique ways of marketing here, it is so effective that it gets a lot of very positive responses from forum members.
Like reviewing casinos, raffles, and others may have been applied here and it is quite effective also in marketing, but we have not found anything unique here that could be the reason for marketing very effectively and gaining massive members, maybe we need a few more creative people here to do more modern marketing and can attract gamblers on the forum, because if you do the same strategy as other gambling platforms I think it will be boring and people will also think it is not very interesting.
