In the TikTok Ads structure, the campaign sets the objective while the ad group decides nearly everything else: who sees your ad, where, with what budget and bid.
Placement: pick TikTok as the main placement; disable external network placements if you want traffic quality control early on.
Audience: start with basic limits (location and age fitting the product) and leave the rest broad. Enable audience expansion so the system can go beyond your audience when it finds better prospects. Interest and behavior targeting are better saved for later test rounds.
Budget and schedule: set the daily budget at no less than 20x your target bid; run 24/7 for the first week so the system finds effective hours itself.
Optimization and bidding: for conversion objectives, optimize for the deepest funnel event your pixel has enough data on (usually start with add-to-cart, later upgrade to purchase). AdHub.la's campaign builder marks required fields and uses the exact TikTok Ads Manager value sets, so you can cross-reference 1:1.
