E-commerce Marketing Agency

Marketing that increases sales
and store profitability

Advertising is supposed to be profitable, not just look good in reports. We scale sales based on margin analysis, CAC, real ROI and MER.

The problem

High ROAS doesn't mean you're making money

Most agencies optimise for metrics that look good in reports — not your bank account. We've seen stores with 400% ROAS running at a net loss every single month.

The Hexthorn fix

01

Break-even ROAS first

Before any campaign launches, we calculate the exact ROAS needed to cover your margin, logistics, fees, and returns. If the math doesn't work, we don't run the ad.

Same client, next quarter: +$36k net profit

02

MER over ROAS

We track Marketing Efficiency Ratio — total revenue ÷ total marketing spend. It's the only number that tells you if your entire operation is profitable, not just one campaign.

Full-funnel visibility, not campaign tunnel vision

03

Profit, not vanity

Every budget decision, every creative test, every channel expansion is evaluated against net profit. Impressions and reach are outputs, not goals.

Budgets scale only when MER confirms it

What we do

A full ecosystem, not isolated campaigns

Every service is connected. Strategy informs ads. Ads inform content. Content informs automation.

Paid Advertising

Google, Meta, TikTok, YouTube — channels chosen by data, not habit. Every dollar tied to your margin and CAC.

E-commerce Strategy

Profitability audit before any campaign launches. We set your break-even ROAS and MER target first.

Video & UGC Studio

In-house production that shortens the purchase path and reduces CAC.

Email & Automation

Flows that recover carts, upsell buyers, and earn while you sleep.

SEO & Content

Organic traffic that compounds. Buyer-intent keywords, not vanity metrics.

Analytics & Reporting

Weekly plain-language reports. Margin, CAC, MER — not just clicks.

Proof

Numbers that actually matter

Revenue, profit, and return on investment — not impressions.

Sales growth

A regional optical salon with stagnant online sales. We rebuilt their funnel from scratch, cut wasted ad spend by 40%, and doubled revenue without increasing the budget.

Return on investment

A UK fashion store spending £6k/month with no clear attribution. After a full MER audit and creative overhaul, every pound spent returned twenty-eight.

Order volume increase

From 75 orders a month to over 900. We identified three high-margin product lines being under-promoted and shifted budget accordingly.

ROI

A children's brand with great products but poor targeting. Audience restructure, new UGC creatives, and a tighter CAC ceiling turned a break-even account into their best-performing channel.

How we work

A repeatable system, not a one-off campaign

Every engagement follows the same five-step framework.

Profitability Audit

We pull apart your entire P&L before touching a single campaign. What's your real margin after returns and logistics? What's your current CAC vs LTV? Where is budget being wasted right now? This audit is the foundation everything else is built on.

FAQ

Common questions

01

What makes Hexthorn Labs different?

We start with a profitability audit — not a pitch deck. Before spending a dollar, we calculate break-even ROAS, factor in margin and logistics, and set a realistic MER target. Most agencies optimise for ROAS. We optimise for net profit.

02

What size of store do you work with?

Stores generating at least $1M in annual revenue with a minimum $10k/month ad budget. Below that threshold, the economics of a full-service engagement rarely make sense for either side.

03

How long until we see results?

We require a minimum 6-month engagement. E-commerce marketing is a compounding process — audit, test, optimise, scale. Quick wins exist, but sustainable growth takes consistent iteration.

04

What is MER and why does it matter?

MER (Marketing Efficiency Ratio) is total revenue ÷ total marketing spend. Unlike ROAS, which measures individual campaigns, MER shows whether your entire marketing operation is profitable. It's the number we use to decide when to scale.
