I built a sample account structure for a small product brand across Business Center, Ad Manager, TikTok Shop and Seller Center: 3 Business Center assets (an event set, a catalog and an ad account), 6 campaigns, 12 ad groups, 24 ads, 4 shop collections, and 3 products with 12 SKUs, 2 shipping profiles and a warehouse. Every product line has both a prospecting and a retargeting campaign, all 12 SKUs can be reached from a live ad, and all 138 links between the centers point at something real. One naming system covers all four centers, and a check rejects mistyped names before they go in. This is the structure the setup follows; ad performance, bids, budgets and shop conversion work are read from the live account's own reporting once there is access, so none of that is shown here.
