01 · Overview

A fast-growing UK-based sports nutrition and supplement brand operating on Awin's Accelerate plan, offering a wide range of protein powders, vitamins, pre-workouts, and wellness supplements. Despite having a large publisher network of 366 affiliates and significant market potential, the brand's program was underperforming — generating inconsistent monthly revenue and failing to convert its broad affiliate base into a reliable growth channel. Our agency was engaged in December 2024 to restructure the program and drive aggressive month-over-month scaling heading into the spring fitness season.

02 · The Problem

With 366 publishers on the network, the vast majority were inactive or generating negligible traffic. There was no segmentation strategy to identify and activate high-potential affiliates, and commission structures were flat with no incentives to reward top performers. Seasonal fitness peaks — New Year resolutions, spring body transformation campaigns — were being missed with no coordinated campaign push. Additionally, 83 pending sales and 2 unresolved transaction queries signalled a backlog in program administration that was damaging affiliate trust and payment reliability.

03 · The Solution

Conducted a full audit of the 366-publisher base and segmented affiliates into tiers based on traffic quality, niche relevance, and historical performance. Introduced a performance-based commission structure rewarding volume with higher rates at 10%, 13%, and 16%. Launched a spring fitness campaign targeting January–May peak buying season, deploying custom creatives, exclusive discount codes, and co-branded content with top fitness bloggers and YouTube supplement reviewers. Cleared the admin backlog — validating 83 commissions and resolving 2 transaction queries — to restore affiliate confidence and accelerate payouts.

04 · The Outcome

May 2025 delivered the program's strongest month to date. Clicks surged from 1,647 in April to 4,598 in May — a 179% month-over-month increase of 2,951 clicks — as the spring fitness campaign hit its peak. Transactions climbed from 50 to 72 (+44%), and monthly revenue grew from £10,372.69 to £13,487.20, an increase of £3,114.51 (+30%). With 83 pending sales valued at £15,607.38 still to be validated, the true revenue impact of May is projected to exceed £29,000 once all commissions clear. Backed by 366 total publishers and a growing base of activated high-performers, the program is on track to deliver £20K+ in monthly confirmed revenue by Q3 2025.
