Digital ad spend is set to rise again. The forecast calls for a 10.3% climb in 2026, hitting £44.7bn and reaching £49.1bn the year after. That sounds like strength. My take is different: headline growth hides deeper cracks in how this industry works.
These numbers matter because ad money shapes what we see, read, and watch. Growth boosts platforms, funds media, and sets the tone for the wider economy. Still, I believe the market is leaning on tactics that won’t age well without real change.
The Promise—and the Catch—In The Forecast
The projection is simple and upbeat:
The digital advertising market is now forecast to grow 10.3% in 2026 to £44.7bn, reaching £49.1bn by 2027.
That outlook suggests strong demand, better targeting, and more inventory across video, search, and retail media. I see the same waves—and I also see risk. Growth can be loud while attention gets quiet. People skip, mute, and scroll faster. Ads load; eyes don’t.
Why The Boom Feels Brittle
This market relies on signals and trust. Both are under pressure. Cookies are fading. Mobile IDs face limits. Policy shifts keep moving the goalposts. The pipes keep changing, but the spend keeps rising. That mismatch worries me more than the headline cheers me.
Here’s what I think is propping up the numbers today—and why it’s not enough tomorrow:
- Video and CTV add inventory, but attention is uneven across services and devices.
- Retail media offers intent data, yet it risks turning every shelf into a pay-to-play slot.
- Automation helps buy faster, while low-quality placements slip through more easily.
- Performance metrics look good short term, even if they don’t grow real demand.
Each of these drivers boosts spend now. Each also carries a cost that shows up later in wasted reach, dull creative, or rising acquisition prices.
What The Numbers Don’t Tell You
Scale doesn’t equal value. A bigger pot does not mean people like the ads or remember them. It doesn’t mean small publishers survive. And it doesn’t mean brands build anything durable.
I keep hearing that better data will fix this. Maybe. But data is only as good as the consent, context, and craft behind it. If we chase clicks over clarity, we will get more clicks and less clarity. That’s not growth. That’s noise.
Some will argue the market has adapted before and will do so again. Fair. But past adaptations leaned on tracking shortcuts and cheap reach. Those doors are closing. The next phase needs better ideas, not just bigger budgets.
What Should Change Now
If we want the forecast to reflect real health, not just spend, we need to act. My view:
- Prioritize attention and outcomes, not only impressions and clicks.
- Buy fewer, better placements with clear context and consent.
- Invest in creative built for each format, measured beyond last-click wins.
- Support independent media to diversify where messages live.
- Be transparent on data use so trust is earned, not assumed.
This shift isn’t moral posturing. It is practical. Ads work when people care. People care when they feel respected, informed, or entertained. Everything else is accounting.
The Bottom Line
The forecast is upbeat, and I’m not rooting against growth. I am arguing for growth that means something. Let’s stop mistaking spend for success. Push budgets into placements and creative that hold attention, protect privacy, and fund real journalism and useful content.
Call your partners. Change your KPIs. Ask for attention metrics, not just reach. Back publishers that add value. And if a tactic can’t pass a plain-language test with your customers, drop it.
Spend will rise either way. The question is whether the market will rise with it.
