Taking four points of category share in pain relief with competitor-focused advertising

Every dollar the brand spent went into the category head terms, where it competed with forty sellers, three of them with far larger budgets. The result was predictable: expensive clicks from shoppers at the very start of their decision, a mediocre conversion rate and 6% category share that hadn't moved in two years.

What the brand kept overlooking was its own review profile. On the specific comparison that mattered — its product against the two incumbents shoppers actually cross-shop — it won on rating and on the exact attribute those competitors were criticized for. That advantage is invisible on a generic category search and decisive on a competitor's product page.

We moved the fight to the place where the brand was already winning.

• Product-targeting on the two incumbents — Sponsored Display and Sponsored Products aimed at their detail pages rather than at the category head.
• DSP product audiences — shoppers who viewed products like the incumbents' and did not purchase, reached off Amazon with the same attribute message.
• Creative built on the differentiating attribute — the one thing the category's reviews complain about, answered in the first image frame and in an A+ module that compares the brand's own range; a named competitor never appears in the content.
• Head terms reduced, not abandoned — a floor kept for presence, with the freed budget moved to competitor placements.

Estimated category share went from 6% to 10% — and revenue from $176k to $340k a month.

The new-to-brand share of orders is the proof that the growth came from outside the existing customer base: 34% to 58%. ACoS improved slightly while all this happened, because competitor placements convert better for this brand than the category head ever did. No price change was involved.
