Fix Your App Before You Buy More Traffic

Blurred figures walking through a brightly lit space with vivid orange, green and blue lighting.

Growth plans get picked apart line by line. Media budgets, CRM performance, loyalty mechanics; all of it gets challenged. What rarely gets challenged is whether the experience receiving all that investment is converting anywhere near as well as it could.

That gap matters, because for a lot of brands the app has stopped being one channel among several. It’s where a serious share of revenue is either captured or lost.

Domino’s UK & Ireland now processes over 75% of its online orders in-app. At Co-op, every £1 put into the membership app and member offers returns £12. For organisations operating at that level, it’s part of the commercial engine.

And yet it’s usually the piece of the plan nobody interrogates. The app gets filed under infrastructure: working or broken, on or off. It seldom gets treated as what it actually is; a commercial asset with a conversion rate you can shift, a load time you can cut in half, and an abandonment point you can locate and repair.

The calculation almost nobody does

Winning new customers costs money, and the bill keeps growing. Media inflation, privacy restrictions and the general scramble for attention all drive up the price of acquisition. Worse, it’s a price you settle again next month, and the month after that.

Conversion doesn’t behave that way. Lift it and the gain lands on every single visitor, including all the ones you’ve already paid to reach. It accumulates over the year and it doesn’t disappear the moment a campaign ends.
So do the math.

Picture an app processing €50m in annual transactions at a 4% conversion rate. Nudge that to 4.2% and you’ve delivered a 5% relative gain. Identical traffic, identical media spend, identical customer base. That’s €2.5m in extra revenue, arriving continuously for as long as the improvement stays in place. Two tenths of a percentage point almost never earns a slide in a board pack. €2.5m of incremental revenue probably should.

Then cost the alternative. Reaching that same €2.5m through acquisition means purchasing 5% more traffic, and purchasing it all over again twelve months later. Lifting conversion usually costs a fraction of that, and it’s more often a matter of locating and removing friction than building anything from scratch.

Set the two options next to each other and the picture gets awkward. A business pouring seven figures into acquisition while shedding customers at the checkout is paying the full rate for traffic it then fails to convert. Before you commit another euro to the top of the funnel, work out what happens if a greater share of the traffic you’ve already bought actually converts.


Product investment isn’t a rival to the marketing budget, it sets the ceiling on what that budget can achieve.

Where the value quietly drains away

From what we see, value tends to escape through four gaps, and they’re rarely the ones teams check first.

  • Speed.
    Every second between intent and action costs you customers. This shows up at key moments; the basket, the payment sheet, or the search results page. Speed work almost never appears in a campaign plan, but it moves conversion faster than anything else available.
  • Reliability.
    A crash rate that looks acceptable on a dashboard looks very different translated into failed transactions. Lose someone’s full basket once and you haven’t just lost that sale; you’ve damaged their confidence in coming back.
  • The journey itself.
    Apps accumulate steps over time; a field added for compliance, a screen added for a feature, a consent prompt that fires at the wrong moment. Collectively, these can add up to the reason someone gives up two taps from the end.
  • What you can actually see.
    Mobile generates rich behavioural data, but only if it is utilised properly. Plenty can tell you their conversion rate, but almost nothing about where the failures happen. Without that visibility, improvement work becomes guesswork.

Every one of these is a product problem, which is precisely why they fall outside the growth conversation and end up parked in a backlog.

Mobile makes the rest of your spend work harder

The best case for improving mobile has very little to do with mobile on its own.
Marketing manufactures attention, and the app decides whether that attention becomes a transaction or simply dissipates. CRM manufactures relevance, and a perfectly timed message is only ever as strong as the experience it delivers people into. Loyalty manufactures a reason to return, and the app is where a customer discovers whether that promise holds up.

Fire an immaculately targeted push notification into a sluggish app and you’ve spent budget engineering frustration. The notification did its job; the product undermined it. All the dashboard records is a disappointing campaign, and the genuine cause goes undiagnosed.

Which is why order of operations matters so much. Optimise acquisition, loyalty and CRM while leaving the underlying experience alone and you cap all three simultaneously. Fix the experience first and identical activity performs better, without a cent of additional spend.

Four questions worth asking before the next budget round

If you want a fast read on whether mobile is earning its place in your business, these tend to expose the answer quickly.

  • What is our app conversion rate, and when did we last try to improve it?
    If the answer to the second half is “not recently”, there is likely value sitting there.
  • Where exactly do customers drop out?
    If nobody can name the top three drop-off points with numbers attached, the instrumentation needs work before anything else does.
  • What would a one percentage point conversion improvement be worth to us annually?
    Run the number; it is usually larger than people expect, and it reframes what a sensible investment in product work looks like.
  • Are we optimising the channels that feed the growth engine, or the engine itself?
    Most organisations are honest enough to admit it is the former.

Growth often starts with what you already have

Growth isn’t always about sourcing more customers. Frequently it’s about converting more of the demand you’ve already generated and paid for.

That’s the case for putting mobile in the growth plan rather than leaving it on the product roadmap. Make the app quicker, steadier and easier to buy through, and acquisition works harder, CRM lands better, and loyalty gets something real to stand on.

So before you spend more filling the top of the funnel, take a proper look at what happens when people arrive at the screen in their hand.


The growth you’re chasing may already be sitting there.
