Overview

The account

Zuma is a trend-focused fashion brand specialising in lingerie, costumes and statement apparel. Its biggest opportunity is peak seasonal demand, particularly Halloween and Q4, when competition and ad costs rise.

The brand had strong products but lacked campaign precision: spend was scattered, bids were reactive and visibility of performance was low. Zuma partnered with Seller AURA to reduce ad inefficiency and make the most of Q4.

The challenge

What was holding growth back

01

High ACoS made scaling hard

At 50.55% ACoS, growing under the existing set-up would only increase losses.

02

Budget wasted on weak keywords

Broad, low-quality keywords brought traffic but few conversions.

03

High-intent keywords underfunded

Terms with strong sales potential lacked budget during the busiest periods.

04

Rising Q4 ad costs

Weak budget control meant the holiday traffic surge raised costs instead of profit.

What we did

How Seller AURA approached it

Negative keyword refinement

Irrelevant, non-purchase-intent terms were blocked, improving CTR and conversion and freeing budget.

Budget reallocation

Budget moved to high-performing ad groups, hero SKU budgets doubled and ad scheduling focused on high-intent evenings and weekends.

Bid and budget optimisation

Bids lowered on costly, low-converting keywords and raised on strong performers, with daily monitoring at peak hours.

Seasonal alignment

Listings and ad copy optimised for seasonal terms, with coupons and campaigns kept uncapped through the peak week.

The results

What changed

  • Total sales increased 1,647% within 30 days.
  • ACoS fell by 72%, and ROAS improved from 1.98 to 7.01.
  • PPC sales grew 12x and organic sales 18x, showing paid optimisation lifted organic visibility too.
  • The campaign structure kept performing through the Q4 holiday period.
