Short-form video advertising on TikTok
The auction, the creative, the budget floor — the three things you actually need to know before picking a platform.
Meta (Facebook + Instagram) runs an auction across Feed, Stories, Reels, Marketplace, and Audience Network. You optimize for a conversion event; Meta's algorithm decides bid and placement. Effective CPM is $6–12, effective CPC $0.80–1.50 depending on optimization goal and vertical.
Feed: 1:1 (1080×1080), 4:5 portrait (1080×1350). Reels/Stories: 9:16 (1080×1920). Video 15–60s. Carousel supports 10 cards. Copy ~125 chars before the truncate. Creative fatigue is the #1 cost driver — refresh every 2–3 weeks.
The algorithm needs ~50 conversion events per week per ad set to exit learning phase. For a $30 CPA that's ~$1,500/week or $6K/month per campaign. Below that, performance is a lottery.
TikTok Ads runs on CPM ($8–12 typical, higher for premium placements like TopView). CPC is available but the platform's optimization heavily favors CPM-bid campaigns. Auction density is lower than Meta but growing quickly; creative quality dominates.
9:16 vertical video (1080×1920), 9-60s (best performance 15-30s), native-feeling — polished ads underperform UGC-style creative here by 2-3x. Sound-on is standard. Captions optional but boost completion.
$500/day ($15K/month) is the practical floor for the Traffic and Conversion objectives to exit learning phase in a reasonable window. Smaller budgets work for Awareness and Video View goals.
