Case studies
Real accounts. Real numbers.
Six brands with six different problems: an eight-month decline, a single-SKU product at $148, a UK launch from zero, a three-SKU catalogue that needed one winner. Here’s what changed, and what the data told us.

US home & kitchen brandHome & KitchenUSJul 2025 – present
From $7.2K to a $20.5K peak month by betting on one product — and having the discipline to stop funding the one that wasn't working.
- Situation
- Scaling
- Starting point
- 3 SKUs · ~$7K a month, no advertising
What the data said
- One product converted at close to half the ad cost of the other two, so it became the product we led with — it went on to produce 61% of all ad revenue. The third got worse every month, not better, with ad cost climbing from 56% to 95% of its sales, so we stopped funding it and moved 18% of the budget across.
- December is a holiday peak. Revenue settled at $10,137 a month by March 2026 — still well clear of the $7,179 pre-advertising baseline.

US men's grooming brandBeauty & Personal CareUSApr 2025 – present
Added ~$11K a month of genuinely incremental revenue by learning where advertising works — and stopping where it doesn't.
- Situation
- Scaling
- Starting point
- 15+ SKUs · ~$20K a month, organic only
What the data said
- Brand-name searches converted at 12–24% ad cost. Generic category terms ran at 134–167% — more than a dollar of spend for every dollar of sales — so every generic campaign was paused and 40 focused ones kept.
- Organic sales did not drop away when the advertising started. That is what makes the added revenue incremental rather than paying twice for demand the brand already had.

US beauty-accessories brandBeauty & Personal CareUSSep 2025 – present
Doubled monthly revenue in six months and turned $160-to-$8.6K swings into a predictable $10–13K.
- Situation
- Recovering
- Starting point
- 3 SKUs · ~$5.5K a month, unpredictable
What the data said
- Competitor brand searches were the most efficient traffic in the account at 8–26% ad cost, and feature-specific search terms converted 2–3x better than broad category terms.
- The same search data exposed a gap in the product line. The variant launched into that gap was profitable within 30 days, not the 6–12 months an unguided launch takes.

From $2K to $30K a month on a single product — then repeated it in Canada in 90 days.
- Situation
- Expanding
- Starting point
- One SKU at $148 · ~$2K a month
What the data said
- Brand-name searches served at 4–5% ad cost, and problem-aware terms beat generic bedding terms decisively — so the budget went to people already looking for a solution, not browsers.
- Canada opened on the search terms and competitor targets the US had already proven, which is why it reached efficient advertising in 90 days instead of paying to learn the same lessons twice.

- Situation
- Launching
- Starting point
- 7 SKUs · new to Amazon UK, no ad history
What the data said
- The niche the category was ignoring paid: dedicated oud and luxury hand-wash terms served at 7–19% ad cost, while broad fragrance terms ran at 46–82% and were cut.
- Pruning 38% of targets let March spend come in 20% below February while ad-attributed sales finished 34.6% above the launch month. TACOS held at roughly 25% throughout.

UK food & grocery brandFood & GroceryUKSep 2025 – present
Reversed an eight-month revenue decline in 30 days, then grew monthly revenue 40% above the declining baseline.
- Situation
- Recovering
- Starting point
- 28 SKUs · £13.5K a month and falling
What the data said
- The decline was a visibility problem, not a product problem: competitors had started advertising while this brand stayed organic-only. Ads went live across all 28 products in month one and revenue stabilised immediately.
- December doubles on seasonality, so the honest comparison strips it out — even then the account runs 23% above the pre-decline baseline, and one overlooked SKU went from £284 to £1,880 a month.

Methodology
How we report these numbers
No blended agency averages, no cherry-picked weeks, no metrics that cannot be traced back to an account.
- Source
- Figures come directly from the advertising and business-report data in the client's own Amazon account, compared like-for-like across the periods shown.
- Seasonality
- Where seasonality distorts a result, we say so.
- Names
- Client names are withheld unless the brand has approved disclosure.
- Caveat
- Results vary by category, price point and competition.
