FAQs

Which is better for Gen Z marketing: Reddit or TikTok?

TikTok has larger Gen Z reach and dominates short-form video. However, Reddit also has strong Gen Z presence, particularly for gaming, tech, and hobby communities. TikTok works better for broad Gen Z awareness; Reddit works better for reaching Gen Z interested in specific topics.

Do I need video production for Reddit ads?

No. Unlike TikTok where video is required, Reddit supports text, image, and video formats. Many successful Reddit campaigns use static images with strong copy. Video can improve performance but isn't essential, making Reddit more accessible for advertisers without video capabilities.
