Of course, signature campaigns are a very good way to advertise a project. The project immediatly gets known to hundreds and thousands of users, but those users are already into crypto and already may know that there are gambling sites which let you gamble with your cryptos.
The main problem is that this potential userbase is currently finite due to the fact that there are not that many new people registering per day compared to eg. 2017. So if a site wants to attract a whole new userbase marketingefforts have to be extended out of the span of this forum, too, in my opinion.
Sometimes I consider if signature campaigns are as great as everyone believes it is. We have been doing signature campaigns for over 5 years as a forum now, and people continue to do it as well which tells me if it didn't worked they wouldn't do it neither.
It does make sense. Signature campaign provides wide awareness on the people especially here in the forum. Not only gambling sites should extend their reach but mostly, they need to surpass their competitors. Marketing is just part of being known, what is more important for these websites is what they features to be known.
But, as soon as a company or a website gets big enough they stop doing it, so it may not really be great for a place that already has a lot of people but might only work for places that are new and want to get their name heard. It is not sustainable forever if you ask me, if it was we would see places that are 5+ years old still doing signature campaigns but not many of them exists. So, all places that are under 1 or 2 years are doing it to keep their names up and "public awareness" is the only true reason for it.
Again the competition for gambling platforms is growing, they should not be too confident just because they have a lot of players at the present. I agree, signature for old websites should still be running up til now if they want to approach the new users and potential players . I guess these gambling platforms find Signature campaign too expensive to sustain for so long just to keep their website awareness, some are pausing their signature and re-opens when they noticed a substantial number of player they have.
