In-Feed Ads
Native 9:16 vertical video ads appearing directly in the For You Page feed
In Simple Words (Zero Jargon):
Standard TikTok video ads that appear naturally in the feed as users swipe, playing with full sound and a clickable button at the bottom.
Why It Is Critical
In-Feed Ads are the primary workhorse format for direct response e-commerce, app installs, and lead generation. They must be 9:16 vertical video with sound-on by default, opening mid-action in the first 1-2 seconds to prevent swipe-away.
