Electronics Amazon PPC case study: sales up 45% in 60 days at a 4.28% ACOS
A full Amazon PPC rebuild for a consumer electronics brand, using exact match keyword harvesting, disciplined bid control and defensive ASIN targeting to scale sales without letting ad cost drift.
A premium smart-device brand, competing in one of Amazon's fastest-moving categories.
This consumer electronics brand sells smart devices built for home entertainment, personal productivity and digital connectivity. The catalog is well engineered and competitively priced, and the brand set out to build a lasting presence in Amazon's technology marketplace.
The objective was to turn a strong product line into consistent, profitable sales growth, with ad cost held firmly below a 5% ACOS as volume scaled.
The problem
The products were strong, but the brand lacked visibility in a crowded electronics marketplace where shoppers compare specs, model numbers and prices before they buy. Without a structured search presence, high-intent shoppers were finding competitors first.
Reaching them meant pairing the product line with precise keyword targeting, tighter control over where ad budget was spent, and protection for listings that already attracted valuable traffic.

A four-part Amazon PPC architecture, built for efficiency at scale.
Four moves, run together, to compound keyword rankings and keep every advertising dollar working on shoppers ready to buy.
-
Advanced keyword harvesting & funneling
Ran an in-depth keyword harvest to find exact match model specifications, high-intent technical search terms and long-tail problem-solving phrases, then funneled them into exact match campaigns to win top-of-search placements.
-
Bid management & placement control
Used automated dayparting and custom placement modifiers to shift most of the budget into the placements with the highest proven conversion rates, cutting wasted spend while lifting sales velocity.
-
Organic ranking acceleration & halo structure
Built a "halo effect" framework that concentrated spend on high-volume, high-margin anchor products. The added momentum lifted core organic keyword rankings and brought in sales that carried no ad click cost.
-
Cross targeting & ASIN defense
Launched defensive product targeting on the brand's own listing pages to block competitors, while Sponsored Display ads targeted weaker, lower-rated competitor listings to win share.
From a spring low to a summer peak, with ACOS under control the whole way.
Ad-attributed sales climbed 45% while the account held a 4.28% ACOS across the entire scaling phase.
Monthly ad-attributed sales
April's low of $277,271.76 became June's peak of $404,561.18, a gain of about 46%.
