Both platforms are visual, both reward authenticity, but they serve different audiences and content styles. Here's how to decide where to focus your event marketing efforts.

Instagram skews slightly older and tends to reward polished, aspirational content. TikTok's algorithm is more democratic — great content can reach millions regardless of follower count.
If your event targets a professional or lifestyle audience and you have strong visual branding, Instagram is your home. Stories, Reels and the grid work together to build a cohesive event presence.
If you're targeting a younger demographic or your event has genuine energy and personality, TikTok's reach potential is unmatched. Raw, authentic, fast-paced content thrives here.
The most effective event marketers repurpose content across both. Film vertically, edit for TikTok first, then adapt for Instagram Reels. The core content is the same — the approach differs slightly.
Copying content directly across platforms without adaptation rarely works. Each platform has its own culture, pacing and audience expectations. Take the time to tailor your captions, audio choices and editing style.
