Overview

A UK-based supplement distributor managing a portfolio of premium, brand-led supplement lines across Amazon UK. The account includes some of the category's most recognisable names in natural nutrition, wellness, and functional health.

We managed the Amazon channel for this client, with responsibility for advertising, listing performance, and channel-level commercial strategy across the full brand portfolio.

Across the most recent 12 months, the account has delivered:

£871,300 in total Amazon revenue on £52,600 of ad spend, a blended TACOS of 6.0%, with paid advertising supporting a business that is now 81% organic.

The Problem

This is a case study about a different kind of challenge. The account isn't struggling, it's mature. The portfolio carries real brand heritage, loyal repeat customers, and strong organic rank. What this client needs isn't aggressive growth fuelled by aggressive ad spend. What they need is discipline.

The commercial reality:

● The portfolio sits at a premium price point. Competing on price is off the table, it would erode brand equity that has taken years to build

● Amazon's default growth lever, spend more, win more, doesn't suit an account where paid media is a small slice of a predominantly organic business

● Overspending on brand defence or non-branded terms directly damages account profitability without delivering proportionate revenue

● Previous seasons had shown spend drifting upward without corresponding revenue growth, a classic sign of an account running on autopilot rather than active management

● With multiple brands in the portfolio, each with its own commercial dynamics, generic management was leaving efficiency on the table across the board

The brief was clear: protect the brand, hold or grow revenue, and do it with less paid media, not more.

The Outcome

The account is running more efficiently than at any point since the engagement began. Across the first four months of 2026 compared to the same period in 2025, revenue is up 5.8% while ad spend is down 22%, a blended TACOS improvement from 7.5% to 5.5% on a portfolio already operating below category benchmarks.

Across the full 12-month window, the portfolio has generated £871,300 in total revenue on £52,600 of ad spend. Organic revenue accounts for £703,400 of that total, over 80%, with paid acting as a precision layer rather than the primary growth driver. Every pound of advertising investment is associated with roughly £16.50 of total revenue across the account.

Multiple individual lines are now running at sub-5% TACOS, with several flagship products operating below 3%, meaning ad spend on those lines is effectively negligible as a share of total revenue. CTR and CVR have improved across the portfolio following a content refresh, further reducing the amount of paid spend required to hold rank and convert traffic at scale.

The relationship has also expanded. In April 2026, Prospera led the ground-up launch of a new Amazon-exclusive line for the same client, a more competitively-priced range built to serve a different shopper and a different commercial dynamic to the premium portfolio. Different strategy, different playbook, same partnership. The fact that a long-standing distributor chose to launch a new brand under the existing engagement, rather than treat it as a separate project or a different agency's remit, speaks to the commercial trust built over the course of the relationship.

Same top line. Significantly less spend. A portfolio of premium brands scaled through discipline, and a new venture launched alongside it.
