The brand
Our client is a bathroom and toilet odour-eliminator spray brand — travel and full-size sprays across five scents, in multi-packs, singles and refills. It sits inside an established fragrance portfolio, but this product line was a brand-new Amazon launch in January 2024: new parent ASINs, no keyword-level sales history, and no organic rank to lean on. The client's name is withheld at their request.
The challenge: a low-ASP, high-CPC niche
Bathroom sprays are a brutally competitive Amazon category, dominated by an established incumbent with tens of thousands of reviews. The unit economics are unforgiving:
- Average selling prices sit under $20, while CPCs were already running above what the margins could comfortably absorb
- A cold listing meant no sales history for Amazon's algorithm to reward — rank had to be bought before it could be earned
- Overspending was unavoidable for a period; the risk was doing it in the wrong order, or failing to pull back once rank was secured
The plan: warm the account up, deliberately overspend to buy the rank we needed, then pull back into profitability without losing the position — in that order.
Our playbook
1. Warm-up with stock discipline
Before scaling spend, we prioritised stock replenishment across every advertised ASIN — going out of stock resets sales history and quietly inflates CPC, so staying in stock through the warm-up window was non-negotiable.
2. Broad test, fast narrow
We launched 45+ testing campaigns across scents and pack formats, then narrowed to the winners within a month — two scents led on ACOS, one on organic pull, and the mixed pack on conversion rate.
3. Fixing the structural leaks
We removed a pocket-size variant that was quietly cannibalising blended ACOS, merged fragmented scent listings into a single parent ASIN to stop the brand competing against itself, and began linking legacy reviews into the new listing.
4. Buying rank on purpose
Weeks 8–10 saw spend nearly double and ACOS climb to 77.55% T30D-over-T30D — a deliberate trade-off to push the sales velocity Amazon rewards with organic rank, tracking TACOS rather than ACOS as the real health metric through this phase.
5. Cutting back without losing it
Once rank held, we tightened keyword pruning thresholds, shifted volume into lower-CPC auto campaigns, and brought T30D ACOS back down to 58.41% by Week 13 — on higher sales and impressions than the account had at launch.
The result
- ACOS normalised to 58.41% — back near the pre-scaling baseline, on a larger, more efficient account
- Core keywords moved from unranked to sub-30, and on priority terms sub-10, within 8–10 weeks
- $51K+ YTD ordered product sales rebuilt from a cold listing, with growth reaccelerating each month
- A clean 20-campaign structure by the 90-day mark, averaging $1.67 CPC and a 12.14% conversion rate
Why this matters for serious Amazon brands
Every serious Amazon launch gets worse before it gets better. Pull spend the moment ACOS climbs and you give up the rank you paid for; never pull back once rank is secured and you bleed margin indefinitely. Knowing which keywords are worth buying rank on — and exactly when to cut back — is what turned this launch around. The same approach is potentially achievable for your brand.
