Ecommerce growth, run like a P&L.
Acquisition, conversion, retention and subscription growth for DTC and ecommerce brands. Extra Medium currently leads growth for consumer brands on Shopify, owning strategy end to end.
What ecommerce growth means here.
An ecommerce growth agency is responsible for increasing an online store's revenue and profit across the whole customer lifecycle: traffic, conversion, average order value, repeat purchase and subscription. It is broader than an ads agency and more accountable than a consultancy.
Extra Medium runs ecommerce growth the way an in-house team would: one plan, one set of numbers, and decisions made on contribution margin rather than ROAS alone. We work primarily with Shopify brands, and our founder currently serves as fractional CMO for a high-growth consumer products company.
You will recognize yourself, or you won’t.
- ROAS looks fine but the business is not more profitable, and nobody has reconciled the two.
- You are dependent on one channel and one product, and growth stalls every time either wobbles.
- Retention, email and subscription are afterthoughts next to acquisition.
- You need a senior operator to own ecommerce growth, not another agency running ads in a silo.
The work, in order.
Rebuild the truth
We reconcile platform-reported results with your actual P&L, so every decision is made on contribution margin, not on what an ad platform claims.
Fix conversion and retention first
Cheaper traffic is rarely the answer. Higher conversion, higher AOV and stronger repeat purchase make every channel work harder.
Diversify deliberately
We expand channels, creators and offers in order of expected return, so the brand stops living or dying on one ad account.
Run the weekly rhythm
Growth is operational. We run the cadence: what shipped, what it did, what is next, with a dashboard leadership can actually read.
Specifically.
- Ecommerce growth strategy
- Paid media across Google, Meta, TikTok and Reddit
- Shopify conversion rate optimization
- Email and SMS lifecycle marketing
- Retention and subscription growth
- Creator, affiliate and influencer programs
- Landing pages and offers
- Analytics, attribution and executive dashboards
- Marketplace and channel expansion
- Fractional CMO leadership
We currently manage monthly investment across Google, Meta, affiliate, influencer, creator, UGC, Reddit and AI-driven channels for a high-growth consumer brand, and we built its creator and affiliate programs into real acquisition channels. Before that, our founder led ecommerce, mobile, merchandising, loyalty and seasonal campaigns for a Fortune 500 retailer across three banners. The through-line: ecommerce growth is a systems problem. Ads are one input. Offer, page, post-purchase experience and retention are the rest of the equation, and they are usually where the money is.
Straight answers.
What does an ecommerce growth agency do?
It owns the levers that grow an online store: traffic, conversion rate, average order value, repeat purchase and subscription, plus the analytics that tie them together. The best ones behave like an in-house growth team rather than a channel vendor.
Do you only work with Shopify brands?
Shopify is where most of our ecommerce work lives, but the strategy, media and retention work applies to any modern ecommerce platform. See Shopify strategy for platform-specific work.
What does ecommerce growth typically involve financially?
A monthly retainer for strategy, execution and reporting, with media spend paid directly to platforms. We scope to the size of the store and the opportunity, and we are direct about whether a brand is ready to scale paid acquisition or should fix conversion and retention first.
Can you act as our fractional CMO for ecommerce?
Yes. Many ecommerce clients want one senior owner for growth rather than a stack of vendors. See fractional CMO services.
