Push ads can function effectively for affiliate marketing within walled gardens, but with some limitations. Walled gardens like Facebook, Google, and TikTok have closed ecosystems, restricting advertisers' access to user data and limiting tracking capabilities. Push ads—alerts or notifications sent directly to users—can still engage audiences in these environments due to their direct, attention-grabbing nature. However, the success depends on the platform's advertising policies and targeting options. While push ads outside walled gardens may allow more freedom for tracking and optimization, inside these ecosystems, marketers must rely on platform tools and comply with strict rules. Overall, push ads remain a viable strategy for affiliate marketing within walled gardens, though effectiveness hinges on adapting to platform-specific constraints and leveraging precise targeting features.
