The TikTok Scaling Dilemma

TikTok ads can be a goldmine for Shopify beauty and fashion brands. But scaling is a nightmare. You have a campaign with a great ROAS, you increase the budget, and suddenly your returns plummet. You are stuck in a cycle of testing and guessing, unable to predictably scale your winning ads. The problem is not your creative; it is your marketing attribution model.

Causality Engine uses causal inference on the GA4 history you already have to estimate what each channel caused.

Finding Your Saturation Point

Every ad platform has a saturation point where additional spend yields progressively smaller returns. The concept of marginal ROAS:

mROAS = d(Incremental Revenue) / d(Ad Spend)

The optimal budget is the point where your mROAS equals your target.
