Who You Reach

TikTok's audience skews younger than Facebook's but has broadened considerably, and it is one of the few platforms where people routinely discover and buy products they had never searched for. Ads appear in the For You feed between videos from creators, which is why ads that look and sound like native content perform best.

Ad Delivery

Like Meta, TikTok runs an auction and optimizes delivery toward the objective you choose, such as traffic, leads, app installs or conversions. The system relies heavily on the first few seconds of each video to decide whether people engage, so the hook of an ad matters more than almost any setting.

Ad Formats That Matter

In-feed ads are standard video ads in the feed. Spark Ads boost existing organic posts from your account or a creator's account, keeping the likes and comments, which adds social proof. TikTok Shop ads link directly to products sold on the platform. Lead generation ads collect contact details inside the app.

Success Factors

Fresh creative, tested often. Most accounts need several new videos every week because audiences tire of the same ad quickly. Tracking also matters: the TikTok Pixel and Events API send website actions back so the platform can optimize for real results.

Putting This to Work

TikTok is a creative platform first and a media platform second. Budget for content production before you budget for ad spend.

In Practice

A skincare brand runs the same polished product video it uses on Instagram and gets poor results. A creator filming a 20-second honest first-use review of the same product costs less to produce and outperforms it several times over.
