Amazon Cell Phones & Accessories Case Studies
Real campaigns we ran for cell phones & accessories brands on Amazon — what was broken, what we changed and what it moved.
Announcement to listing live: 26 days → 9
Publishing in 48 hours instead of four weeks after a device announcement
In phone accessories the ranking race for a new device is decided before the device ships. The brand's listings arrived a month late every time, so we rebuilt the publishing process around the announcement date.
Write-offs $340k → $61k a year
Retiring SKUs on a schedule instead of discovering dead stock
Phone accessories die when the device they serve does, and this brand kept finding out afterwards. A retirement ladder tied spend, price and inventory to the age of each device generation.
Sessions 77k → 95k
Selling a phone case as a style, not as a protection spec
The brand's copy argued about drop ratings while its buyers were searching for an aesthetic. Rebuilding the catalog around style vocabulary moved it into a set of searches it had never appeared in.
Branded searches under 400 → 11k / month
Creating a branded search term in a category of anonymous sellers
Screen protectors are sold by hundreds of interchangeable names using the same stock photography. We spent ten months making one of those names something shoppers type on purpose.
ACoS 39% → 20%
Buying the moment somebody's old cable stops working
Cables are not bought, they are re-bought — usually in irritation, the day the last one fails. The brand was bidding on product terms and ignoring the language of the failure that creates the purchase.
Rating 3.8 → 4.2
Publishing the capacity customers actually get
Every power bank in the category advertises a cell capacity nobody ever receives, and every review section is full of people who feel cheated. The brand won by printing the honest number.
+127% revenue from the same four SKUs
Breaking one over-merged listing into the four products it really was
Four mounts for four completely different situations had been merged under one parent to pool reviews. The pooled reviews were worth less than the relevance the merge destroyed.
Returns 17% → 5%
The product was fine; the app it shipped with was the problem
A gimbal brand's reviews complained about hardware that worked perfectly. The failure was the first fifteen minutes with the companion app, and it was being paid for in returns and one-star ratings.
Account return on spend 2.1x → 4.8x
Measuring a 19-day decision with a 7-day report
Nobody buys a $460 phone in one session. The brand was judging campaigns on a report window shorter than its own customers' decision, and switching off everything that builds demand.
Indexed search volume +3.4x
The same product has four names, and the listing knew one of them
Band, strap, bracelet, loop — shoppers call the same object different things depending on where they learned the word. The catalog was indexed for one of the four.
