Projects aren't required to instant making advertisement without proper planning, any projects or gambling site that wants to involved in marketing are those who have already map out some cool funds for advertisement and it has some certain duration to last. All less they already starting making profits from as they launched which might propelled them increase their period of promotion.
Casinos or projects that don't continue their campaigns are obvious because they don't get a good impact from the campaigns that are being carried out. but to see results they cannot in a short time, they must at least measure success in a certain period. and during that period the casino must have sufficient funds to pay out.
most of them finished very quickly because they did not have strong funds for their marketing allocation. so they will focus on project development first.
That is it, most of those project couldn't hold to finish development properly before coming into marketing, we all know that marketing is what gives a project the required exposure but what they fails is that focus on concept of their development than promotion.
While most of struggles because they are highly competitive, which most of them couldn't meet up with some of the standard could as well results folding up.
I think it would be better if development, marketing, promotion and even advertising, were better done concurrently for a new gambling business. if this is done simultaneously, of course, it will attract more attention of new users. when doing advertisements or promotions, there are always improvements or developments that make gamblers think that the new casino is serious about growing its business.
on the other hand, new users who know that there are always improvements at the casino, of course customers will trust more to gamble there and new casinos must provide any promotions or features that make users feel at home and be able to compete with old casinos.
even when doing a campaign and not getting anything good, don't stop the campaign, it will make users think that there is no seriousness in doing development and think that the new casino doesn't have big enough bankroll, which makes customers doubt.
