Anyway, social media is probably the NOW and the nearest future of iGaming/Gambling promotion. Although most operators still uses affiliate networks and partnerships as core of their marketing strategies.
Maybe what you said above might make sense, because iGaming prefers to advertise on social media, you must know that social media is currently a routine role model for various advertisements and content, social media activity currently has a large percentage than advertising in other channels.
I consider iGaming advertising on social media to be one of the most effective places to introduce various things related to iGaming, in my opinion social media is very optimal and affordable for many people, anyone who visits social media will have a great opportunity for iGaming to download the game.
Overall, social media is one of the means to become an advertising partner for iGaming and one of the best strategies for advertising.
