Overview

The Client

Our client is a UK-based fashion e-commerce brand selling premium clothing and accessories online. They had been running Facebook and Instagram ads in-house for over a year but were seeing inconsistent results — some months profitable, most months breaking even or losing money.

They approached RETAILECO with a clear brief: make their Facebook ads consistently profitable and scale their revenue without sacrificing margin.

The Brief

What They Needed

A complete overhaul of their Facebook advertising — from pixel setup and audience structure to creative strategy and campaign optimisation. They wanted profitability first, then scale.

No vanity metrics. No excuses. Just consistent, measurable return on ad spend they could rely on month after month.

The Problem

Challenges We Identified

Poor Audience Targeting

Ads targeting broad audiences with no segmentation, wasting budget on cold traffic unlikely to convert.

Weak Creative Performance

Static image ads with low engagement and no video content to stop the scroll and tell the brand story.

No Retargeting Strategy

No campaigns targeting website visitors or cart abandoners — the warmest prospects were being ignored entirely.

No Data Structure

Facebook Pixel not properly configured, causing inaccurate reporting and poor campaign optimisation signals.

Our Approach

The Strategy We Executed

Full Account Audit & Pixel Rebuild

We started with a complete audit of the ad account and rebuilt the Facebook Pixel and Conversions API setup to ensure accurate data tracking from day one.

Customer Research & Audience Architecture

We built detailed buyer personas and structured the account into three tiers: cold (interest & lookalike), warm (engagement & video views), and hot (cart abandoners & visitors).

Creative Production & Testing Framework

We produced 12 video ads and 18 static creatives. A structured A/B testing framework allowed us to identify winning creatives quickly and scale what worked.

Full-Funnel Campaign Structure

Campaigns restructured across the full funnel — broad prospecting at the top, social proof retargeting in the middle, and urgency-driven offers for cart abandoners at the bottom.

Weekly Optimisation & Scaling

Weekly reviews covering creative fatigue, audience performance and cost metrics. Winning ad sets were scaled methodically to maintain ROAS during growth.

"RETAILECO completely transformed how we approach Facebook advertising. We went from guessing to having a clear system that consistently delivers profitable results. The 3.8X ROAS speaks for itself."
