STRATEGY & EXECUTION
We don’t just tell you what we’d do. We take responsibility for the execution. From Meta Ads and performance creative to products, launches and the day-to-day decisions behind profitable customer acquisition.
Campaigns, budgets, testing, daily optimisation and scaling. We monitor performance and make the day-to-day decisions for you.
We turn your existing content and assets into Meta-ready ads, continually testing new edits, formats, hooks and messaging.
New collection launching? Bestseller taking off? Stock running low? We keep your acquisition strategy aligned with what’s actually happening in your business.
Clear reporting on what’s working, what isn’t and where we see the next opportunity, with proactive advice across acquisition, products, stock and profitability.

BUILT FOR FASHION
We’ve built and grown fashion brands ourselves, so we understand the commercial reality behind the ad account. What to buy, what to push, when to scale, when to hold back, and how stock, margins and seasonality change the decisions you make.
That experience shapes how we manage your growth, not just your Meta Ads.
THE FASHION GROWTH FRAMEWORK
Our approach connects the commercial decisions behind your brand with the way we acquire customers and scale growth.
We identify the products most capable of acquiring new customers, then use paid spend to put more demand behind what’s already proving itself.
We look beyond platform ROAS to MER, acquisition costs and margin, so we’re scaling revenue that actually makes commercial sense.
We build and test advertising around the products, messages and formats most capable of driving sales, without losing what makes your brand distinctive.
We align spend with inventory, launches and real-world demand, scaling when the opportunity is there and adjusting when stock or seasonality says otherwise.
BEHIND OUR STRATEGIC DECISIONS
Products, customer mix, stock, acquisition costs and profitability, giving us the visibility to know where to push, where to pull back and where the next opportunity is.
Live breakdown of performance, profitability, and new customer metrics, updated weekly. We track MER, aMER, nCPA, profit, and retention in one place, so every decision is grounded in real numbers, not gut feel.
Weekly visibility on your top-performing products, ranked by sales, new vs. returning buyers, and revenue share over time. We use this to double down on what’s working and stop wasting spend on slow movers.
Know your numbers before you grow, and as you grow. This tool tracks your break-even MER, aMER, and profit margins based on real-time AOV, costs, and spend. We use it to guide decisions at every stage of growth, so scale never comes at the expense of profit.
We don’t just optimise weekly. We plan and measure performance across seasons, launches, and entire growth cycles. Our Annual Growth Tracker gives you a clear view of revenue trends, ad spend efficiency, AOV, retention, and profitability, so you grow with clarity, not chaos.
CLIENT EXPERIENCE
“We ran out of stock on a Saturday, they saw this and reduced ad spend so we didn’t waste budget on Sunday. Really impressive.
I’ve never worked with an agency that was so proactive.”
Founder, Carved
“Christiaan and the team at Heavy Head Social are extremely knowledgeable when it comes to running Meta Ads, particularly within the fast-paced world of fashion where trends and demands can change daily.
Their expertise has been invaluable in helping us stay agile and responsive in our campaigns.”
Operations Manager, Wardrobe Plus
COMMON QUESTIONS
We work exclusively with fashion eCommerce brands. From apparel and footwear to jewellery, accessories and other fashion-led categories. Most already have an established customer base, proven products and consistent sales, and are looking for an experienced team to take ownership of Meta Ads and help them acquire more customers profitably.
You’ll work directly with Christiaan and Hollie, the founders of HHS. We stay closely involved in every client account, from strategy and performance to the decisions that shape what happens next. Behind the scenes, we work directly with our team to manage the day-to-day execution, so you get founder-level involvement without having to manage multiple people.
Yes. Meta Ads is our specialism.
But we don’t manage it in isolation. Products, stock, margins, launches and creative all affect what should happen inside the ad account, so we use that information to make better decisions about what to promote, when to scale and where to put your budget.
You shouldn’t need to manage your Meta Ads, or manage us managing them.
We handle the day-to-day campaigns, budgets, optimisation, creative testing and decisions. We’ll need you to keep us informed about things like launches, stock and business priorities, but our job is to take the channel off your plate.
Every brand is different, so we won’t promise a particular ROAS, CPA or revenue increase before we’ve looked at your business.
What we can show you is what we’ve achieved across 100+ fashion brands. If you request a Fashion Growth Audit, we’ll look at your current position and show you where we believe the biggest opportunities are.
