The Channel Paradox – Why Your Fast-Payback Channels Are Costing You Profit

Written by Sara de Velasco on . Posted in News.

There’s a paradox sitting in most marketing budgets right now, and it’s invisible until you look for it.

PPC gets you 79% of your profit back within 12 months. But across a £100K spend, it only generates £280K total profit.

TV? 57% payback. But it generates £1.6M.

We’ve optimised ourselves into a corner. We chase the channels with the fastest returns because they’re easier to measure, easier to justify, easier to report on. Month-on-month ROI looks brilliant. The board is happy. And we’re leaving the biggest profits on the table.

This is what The Growth Gap Report calls the efficiency trap. We’re squeezing for short-term returns and missing the long-term scale.

Why This Matters (And It Matters to Everyone)

This shapes how you allocate budget and how you think about channel strategy. Both roles are trapped in the same problem: the metrics that look best in the moment are not the metrics that deliver the most profit.

Here’s the core issue: speed and scale are not the same thing.

Fast channels (PPC, paid social, online display) deliver profit quickly. They’re brilliant for near-term ROI. You spend a pound, you get measurable returns within weeks. The data is clean. The causation is clear. You can report on it Tuesday morning.

Big channels (TV, print, audio, outdoor) deliver much more total profit. But they take longer. They build brand value that compounds over time. They work partly through brand association, partly through reach and frequency, partly through things we can’t measure as neatly. The returns are slower, but they’re bigger.

Most teams have chosen speed. We’ve built our entire strategies around performance marketing. And it’s working (sort of). The issue is what we’re not doing. We’re not balancing both.

The Data: What The Growth Gap Report Reveals

The Growth Gap Report analysed how much profit different channels generate from a £100K investment, and how much of that profit lands within 12 months versus later.

Here’s what it found:

Fast-payback channels (but smaller total profit):

  • Generic PPC: 79% of profit in year one. Total: £280K.
  • Online Display: 76.5% in year one. Total: £180K.

Slower-payback channels (but much bigger total profit):

  • Total TV: 57.3% in year one. Total: £1.6M.
  • Print: 64.6% in year one. Total: £900K.
  • Audio: 68.7% in year one. Total: £620K.

The gap is not small. TV generates 5.7 times more total profit than PPC. Even print generates 3.2 times more than PPC.

Why? Because these channels build brand. They reach people who aren’t searching for you right now, who aren’t in your immediate consideration set. They shift how people think about your brand over time. They create an asset that grows in value. And they do it at scale.

The Channel Allocation Problem

Most marketing budgets look the same: heavy on search and social, lighter on everything else. It feels efficient because performance channels are easy to optimise and easy to track.

But here’s what The Growth Gap Report found about actual versus optimised spend allocation:

Current allocation looks like:

  • Digital performance (PPC, paid social): 60-70% of budget
  • Digital brand (display, video): 10-15%
  • Broadcast and print: 15-30%

Optimised allocation for profit looks like:

  • Digital performance: 35-40%
  • Digital brand: 10-15%
  • Broadcast and print: 40-50%

The recommendation is not to abandon performance marketing. It’s to rebalance. Shift some budget from the channels that pay back fastest to the channels that deliver the most profit.

This creates a problem for every media team: the optimised allocation delivers more total profit, but less profit in year one. Your near-term ROI gets worse before it gets better.

That’s why most teams don’t do it. We’re measured on this quarter, this half, this year. We’re not measured on the profit we’ll generate in three years from the brand we’re building now.

How to Think About This: The Speed-Scale Framework

Instead of optimising for speed or scale separately, you need to optimise for both.

Speed (the job PPC and paid social do): Get profit back fast. Capture demand that exists right now. Reach people in active consideration. Generate cash flow and prove ROI quickly.

Scale (the job TV, print, and audio do): Build lasting brand value. Reach people outside active consideration. Create associations that shift how people think about your category. Generate much bigger total profit, even if it takes longer.

The winning teams right now are doing both. They’re not choosing between them. They’re balancing.

Here’s how to think about rebalancing:

1. Segment your profit horizon

  • What profit do you need in the next 12 months? (Speed channels)
  • What profit do you want to generate over the next 3-5 years? (Scale channels)

Most teams answer only the first question. The second question is where the real money is.

2. Measure both metrics

  • Track short-term ROI for performance channels (it should look good)
  • Track long-term brand lift for broadcast channels (use brand tracking studies, awareness lift, consideration shift)

Don’t compare them apples-to-apples. They do different jobs.

3. Rebalance incrementally
Don’t flip your entire budget overnight. Start small. Move 5-10% from performance channels to scale channels. Measure what happens to your total profit over 18-24 months. The numbers will change how you think about this.

The Uncomfortable Truth

The channels that deliver the most profit are the ones that are hardest to justify in a Monday morning meeting.

TV is expensive. Print is old-fashioned. Audio is invisible. OOH is in the background. None of them give you clean last-click attribution. None of them let you say “we spent £X and made £Y”. You have to trust the data that shows they work at scale.

This is why most teams don’t do it. It’s easier to optimise for metrics you can see on a dashboard than for profit you won’t fully realise for two years.

But that’s also why there’s a £32 billion opportunity sitting in the market right now. Most UK brands are leaving long-term profit on the table because they’re too focused on short-term ROI.

The brands that fix this get to pick up that profit. The ones that don’t keep optimising themselves into smaller and smaller returns.

What’s Next

This post is the thinking piece. The framework for how to rebalance is the what. But the how – the practical steps for working out your optimal channel mix, the conversation to have with your finance team, the way to report on this to your board – that’s different.

That’s where most teams get stuck. They understand the insight. They don’t know how to action it.

If you’re sitting with this tension right now – you can see the profit on the table, but you’re not sure how to restructure without crashing short-term ROI – that’s what we work on with our clients at Hurst Media Agency.

We help you map your current channel efficiency, work out your optimal allocation for total profit (not just near-term ROI), and build the business case to move budget without breaking the board.

Book a consultation with our team and we’ll walk you through your specific situation. We’ll show you what rebalancing could look like for your brand, and what the profit opportunity actually is.
