eCommerce Case Studies With the Working Shown
Three engagements, three different problems, one operating system. Every number below comes with the methodology that produced it — because a metric without a method is just a claim.

Six engagements, with the working shown
Every case study is classified on four axes — service, platform, industry and market — so you can find the one that matches your situation rather than the one we happened to feature. Each chip links to the page that owns that term.
A free-shipping promise was quietly eating the margin on the products the ads pushed hardest.

- Our Methodology
Why these engagements worked
The same four-phase system runs on every account. It is deliberately boring — consistency is what makes results repeatable rather than lucky.
01
Diagnose
Fifteen days inside analytics, ad accounts, marketplace health and the technical stack. Every finding scored by revenue impact and effort.
02
Prioritise
A 90-day roadmap agreed before work starts, with a forecast, named owners and the metric each workstream answers to.
03
Execute
Two-week sprints. Nothing ships without tracking attached, and every test is documented whether it wins or loses.
04
Compound
Monthly business reviews, quarterly replanning, and a standing recommendation each quarter about what to stop doing.
A note on attribution. Every figure on this page is measured against a pre-engagement baseline over an equivalent trailing period, using the client’s own analytics and platform reporting rather than our platform-attributed numbers. Where seasonality or a product launch contributed materially, we say so in the full case study document.

- Client Testimonials
In their words
“They were the first agency that talked to us about contribution margin instead of vanity ROAS. Six months in, we are spending more and keeping more of it.”
Marisa Chen
VP Growth, Nutriblend
“Our Amazon catalog was a mess after three years of quick fixes. They rebuilt it properly, and we recovered the Buy Box on our top sellers within a quarter.”
Devin Okafor
Founder, VAC Vacuums
“The replatform was the smoothest project our team has run. No traffic dip, no ranking loss, and the site is three times faster.”
Priya Raghavan
eCommerce Director, Kitchenary

- Case Study FAQs
Fair questions about these numbers
Are these results typical?
No result is typical, which is why we publish the methodology alongside the number. What is consistent is the process: diagnose properly, fix the operational floor, then scale what compounds. On the audit call we will give you a realistic range for your category, margin structure and starting position rather than pointing at someone else’s best quarter.
Why don't you show more clients?
Several of our largest accounts are under NDA or would rather competitors not know who runs their growth. We will connect you with references in your category privately after the audit, including ones whose numbers are less flattering than these.
How long did each of these engagements take?
Nutriblend hit those figures at month eleven. VAC Vacuums recovered the Buy Box within one quarter, with sales figures at month nine. Kitchenary’s replatform ran fourteen weeks, with the traffic and conversion numbers measured twelve months post-launch.
Do you work in my industry?
Probably. The nine categories listed above cover most of our book, and the operating system underneath is the same. Where we genuinely lack experience, we say so — we have turned down regulated categories where we could not add value fast enough to justify the fee.
What happens if the results do not come?
The agreement is month-to-month after the first 90 days, so you can leave. Before that, we will have flagged the problem ourselves in a monthly review — we would rather tell you a channel is not working than wait for you to notice.
Can I see the actual audit you would run for us?
Yes. Book the free strategy call and we will run it on your accounts before we speak. You keep the scorecard regardless of what happens next.
Want a case study with your name on it?
Start with the free audit. We will show you where your revenue is leaking, what it is worth to fix, and whether we are the right team to do it.
