Sponsored Brands Video With Weak New-to-Brand
A brand launches a Sponsored Brands video campaign for a new $35 product line, targeting category keywords and competitor brand terms. After 45 days: 1.2M impressions, 0.28% CTR, $3,200 spend, $6,400 sales, 50% ACOS. The account target is 30%. New-to-brand (NTB) share of orders is 71%. The brand's existing flagship product sells for $30 and has strong organic ranking; the new line is meant to recruit new customers. The advertiser's manager says "50% ACOS is a failure - kill it and move the budget to Sponsored Products on our flagship." The flagship already runs at 18% ACOS.
1. Is the manager right that 50% ACOS means failure? Use the NTB data and the strategic intent to argue the case.

The manager is applying the wrong yardstick. 50% ACOS on a new product line whose explicit job is customer acquisition is not the same as 50% ACOS on a mature product.
- 71% NTB is the headline. Nearly three-quarters of orders are customers the brand did not have. Those customers have a repeat-purchase path; the first-order ACOS understates lifetime value. If the product has any repeat rate, the blended CAC across the customer's life is far below 50%.
- The flagship comparison is a trap. The flagship's 18% ACOS reflects a mature, organically ranked product harvesting existing demand. Moving budget there buys more of the same customers at a lower ACOS - efficient, but it does not recruit. The new line exists to expand the customer base; judging it against a harvest campaign's ACOS defeats its purpose.
- Sponsored Brands video is a discovery format. 0.28% CTR is modest but not alarming for video; the format's value is awareness + NTB, not bottom-funnel efficiency.
So the campaign is doing its job - it is expensive per order but is buying new customers. The real question is whether the CAC is acceptable against LTV, not whether ACOS beats 30%.
2. What should the advertiser actually change, and how should this campaign be measured going forward?

Diagnose before killing. Break down by targeting: competitor brand terms vs. category keywords. Competitor conquest often has high NTB but poor conversion; category keywords may convert better. Also check the video's first 2 seconds and the landing page - a 0.28% CTR on video can indicate a weak hook, not a weak audience.
Changes:
- Reallocate within the campaign, not out of it: shift budget from the worst-converting competitor terms toward category terms that show NTB and conversion.
- Set a separate ACOS target for acquisition. E.g., 45-50% ACOS is acceptable if NTB ≥60%. Codify this so the campaign isn't judged against the 30% harvest target.
- Add a retargeting layer. Use Sponsored Display to re-engage video viewers and product-page visitors - cheap second touch to convert the awareness the video bought.
- Fix the creative if CTR stays below ~0.3% after two weeks of testing.
Measurement going forward:
- Report NTB orders, NTB sales, and cost per NTB customer as primary KPIs; ACOS secondary.
- Track a 90-day repeat rate on the new-line cohort to validate LTV.
- Compare cost per NTB customer here vs. other acquisition channels - that is the true decision metric, not ACOS.
Only kill the campaign if cost per NTB customer exceeds what other acquisition channels deliver.
