Most ecommerce brands underperform because no one's accountable to the numbers.

Not because the strategy is wrong.

Marketing dashboards are full of impressions, sessions and engagement metrics. Useful, but rarely the numbers your CFO is asking about — which is why so many ecommerce teams find themselves caught between marketing reports that look healthy and finance reports that don't add up.

We built Glass Digital around accountability to the numbers that decide whether a channel is working: revenue, ROAS, contribution margin. Not because results are something we sell, but because they're the only way to know what we're doing is worth doing. If we can't prove a campaign is working, we change it. If you can't see what we're doing, we tell you.

And we know the specific problems in every channel we run:

SEO

If any of this sounds familiar:

  • Paid search costs climbing while organic stays flat
  • A migration that wiped out rankings overnight
  • Content programmes that read well but don't rank
  • A backlog of technical issues nobody's prioritising
  • Algorithm updates you only hear about after they hit you
PPC

If any of this sounds familiar:

  • ROAS targets tightening while spend keeps going up
  • Bid strategies that haven't been touched in months
  • Reports full of impressions when finance asks about margin
  • Google Ads and Microsoft Ads being run by separate people
  • An account that hasn't been restructured since 2022
Affiliate

If any of this sounds familiar:

  • A programme on autopilot since the last agency set it up
  • Cashback partners cannibalising your paid search
  • Influencer programmes that look busy but don't move revenue
  • No idea whether affiliate sales are actually incremental
  • An untapped channel competitors are already winning in

If any of this sounds like the position you're in, we should probably talk.

Case studies

Real ecommerce brands.
Real numbers.

Three programmes across three channels — different starting points, the same operational discipline.

PPC

2,772%

ROAS — every £1 spent returned £27.72

  • 2× ROAS doubled in 14 months — no increase in monthly budget
  • +38% conversion rate growth year-on-year

A Performance Max + Shopping account engineered for efficiency — same spend, twice the return, every product type pulling its weight.

SEO

+1,502%

organic traffic over 24 months

  • +1,514% growth in top-3 keyword positions
  • Compounding organic growth across consecutive years

A combined technical SEO, content and digital PR programme — built to compound. The longer it runs, the steeper the curve.

Affiliate

31%

of online revenue from affiliate

  • 2× the industry benchmark for affiliate revenue contribution
  • +50% revenue contribution growth year-on-year

A multi-territory programme where affiliate isn't a side bet — it's the dominant revenue channel, growing fastest of the lot.

Want the detail behind these numbers? We'll walk you through the closest match to your business on the audit call — no decks, just the working.

Why brands choose us

Built differently — on purpose.

Most agencies look the same once you've pitched a few. The differences that matter are operational — how the team is paid, how audits are written, how the work is staffed, and what the pricing actually reflects.

01

Your campaign team gets a bonus when your campaigns hit theirs.

Most agencies pay account managers on retainer revenue — meaning their incentive is more clients, not better results. Our PPC and affiliate teams get performance bonuses based on campaign results. So when your account improves, theirs does too.

02

An audit that tells you what's wrong, why, and what we'd do instead.

Most agency "audits" are pitch decks dressed up as analysis. Ours aren't. You'll get specific issues with your current campaign, the reasoning behind each one, and what we'd change — plus competitor analysis showing where you sit in your market. Most prospects keep the audit whether they hire us or not.

03

Specialists who only do their channel — not full-stack generalists.

Our SEO team only does SEO. Our PPC team only does PPC. Our affiliate team only does affiliate. No 'digital marketers' splitting their attention across three disciplines. The depth shows up in the work — and on the calls.

04

You pay for the work, not the overhead.

Most agencies pass on the cost of their operation — premium offices, large leadership teams, expensive sales operations — through retainer fees that don't reflect the work itself. We've built Glass Digital to run lean: senior specialists doing the work, not layers of management above them. The result is retainers that are typically 20-30% lower than the agency average for comparable scope, without the trade-off in expertise or platform access.

What we do

With our three core digital marketing services — search engine optimisation (SEO), pay-per-click marketing (PPC), and affiliate marketing — we can reach and engage your potential customers wherever they spend time online.

If you need help choosing the most effective channel(s), we can provide honest advice based on your business goals, budget and wider marketing strategy.

All of our digital marketing services are delivered by dedicated teams: specialists who are immersed in the industry and know their discipline inside-out. In the ever-evolving digital sector, their vast knowledge, experience, passion and adaptability is key to making your campaign a success.

You will have regular contact with everyone working on your campaign — not just an account manager. This means you get updates, advice and answers direct from the person who knows best and have the opportunity to collaborate on every project. Visit our about us page to learn more.
