Building on the internal linking idea of using movie sites for iGaming ads, I've found that adult sites with high engagement also convert exceptionally well, with one campaign yielding a 25% increase in depositing players. The key is to target sites with complementary demographics, such as age and interests, to maximize ad relevance. For SMS marketing, I've achieved open rates of up to 30% by using personalized messages with the player's name and a sense of urgency, such as limited-time bonuses. Email marketing can also be effective, but it's crucial to segment lists and use triggered emails, like abandoned cart reminders, to re-engage players and prevent list fatigue.
