I think that all such referrers try all the ways to promote their referral link. But i don`t sure that the "social" links would be profitable than "review" site. I think that social links can`t promote several casinos - it seems strange that someone uses several casinos the same time and think that all of them are wonderful.
I'm not sure either, but I think referrers will still use various ways to promote their review sites or other sites. And for that, they are willing to spread the link to get people who will join through the referral link. It's possible that they'll share the link on forums other than here because the more they share the link on more sites, the more they can get new people to join. And I don't think it's that strange to see someone using several casinos at the same time and then make a review of them. If the reviews are okay and honest, I guess they can get someone new.
There are lots of review sites with the copy-paste reviews. It means that their owners don`t cares about the quality of the content and what casinos they promote. They need only to get profit from everybody who becomes a referral.
But of course there are several high quality sites, that have a interesting reviews, made with the owners tests and feedback from the real users. In such situation i can only applaud to such referrers.
A referral link you can get in any casino i think. But it is a way for different "review" sites. They can post links to different casinos. The problem here that lots of peoples copy-paste reviews and don`t matter about casino quality. They get some profit and don`t cares the security of the referrals. Someone, for recommend just one casino looks more fair.
Those who run affiliate marketing websites and provide sites with referral links for others to join, can't go with just one link or one platform as they need to provide multiple options for everyone to choose from, and that is a good strategy considering the different preferences people usually have.
Some people might not like the single casino one is promoting, so they will lose a potential referral this way, but if they have more options available, the person will look for other options and might join one of the platforms under them, so which earns them a referral which they possibly could lose if they didn't have different varieties. So that is the basic reason why people review many different casinos and provide affiliate links to all of them.
It is true for high quality reviews, but the most part of such sites copy-paste reviews without any tests. They don`t care about security of the gamblers, quality of the casino. And that`s why i don`t like all these sites and reviews.
