Every agency calls itself something. Growth agency, digital partner, full-funnel, whatever the phrase of the moment is. It's an easy line to put on a website. It doesn't mean much until you can point to what it actually changes about how you work.
Most "growth agency" claims are a services list
Before we made the right hires, we were, in practice, a narrower agency depending on which service a client came in for. Sometimes the SEO agency. Sometimes the web agency. The people in each discipline could go deep inside their own channel, and did. What we couldn't do was look across all five and say honestly where a client's real growth problem sat, because that call needs genuine expertise in every channel, not just oversight of them.
That's the gap between listing five services and being an eCommerce growth agency. Most agencies with five departments can give you the list.
What changed for us: five services, five owners
For us, "eCommerce growth agency" started meaning something specific once we had real expertise sat in each of our five core services:
• SEO
• Website
• Branding
• PPC
Not one generalist team doing five things adequately. A specialist owning each one properly.
It changed when we made those hires and could put together packages that genuinely combined all five, built from an audit across every channel at once rather than one service sold alongside the others. That's the point the label stopped being aspirational and started being something we could deliver on.
A growth agency should be able to tell you it isn't what you came for
That changes the first thing we do with a client. It isn't fixing SEO or rebuilding a website in isolation. It's looking at every channel a client's customers might actually be searching through, and being honest about where they need to show up and where they don't.
Sometimes that means telling a brand the thing they approached us about isn't their biggest problem. An agency that only sells one service structurally can't give that answer.
Where your customers search has changed
That list of channels has moved too. It isn't just Google any more. It's social search, and increasingly the AI tools people use to research before they buy. We're seeing clients win visibility in AI Overviews off the back of on-site and off-site work running together rather than separately.
If your customers are searching for you somewhere and you're not there, that's a growth problem, whatever channel it happens to sit in.
The part most growth agencies miss: what happens after someone buys
It's easy to build a plan that gets someone from an ad, or a search result, into a purchase, and stop there. That's the default, because acquisition is the obvious, visible bit.
But if PPC and SEO are bringing people in and nothing joins that up with what happens after the sale, you're leaving growth on the table that's usually cheaper to capture than the next new customer. Email is the clearest example. The customer who bought once because of a paid ad or an organic search result is worth more the second and third time, and the channel that brings them back costs less than the one that won them in the first place.
We see the same thing on the way in. Ad campaigns pointed at CRO-optimised landing pages rather than standard product pages have driven big increases in both email list size and revenue for clients. That isn't chance. It's two channels built to hand off to each other.
A growth agency, to me, is one that treats the second purchase as part of the same plan as the first, not as somebody else's job further down the line.
How to test whether an agency is built for growth
If you're an eCommerce brand deciding who to work with, the number of services on offer isn't the test. Ask instead:
• Are those services built to hand off to each other, or run as separate plans? • Who owns making sure they do?
• Can they tell you your problem sits in a channel you didn't come to them about? • What happens after somebody buys, and who's accountable for it?
Acquisition into conversion into retention, on purpose, across search, social and the AI tools customers are starting to use to find products in the first place. That's the version worth paying for.
