The digital marketing landscape is shifting faster than most brands can keep up with. Between the EU’s tightening grip on data privacy, the UK’s own evolving regulations under the ICO, and a global push toward consent-first data collection, the pressure on marketing teams to get their measurement foundations right has never been greater.
So when Didomi - one of the leading voices in consent and data governance - hosted an exclusive industry forum last month, and our very own Queen of Data, Imogen, was invited to speak, we knew this morning was not one we wanted to miss.
Here's the hot takes from her session.
If you’ve been in digital marketing for the last couple of years, you’ll be familiar with the chaos that followed Google’s switch from Universal Analytics to GA4 in 2023. The short version: the way GA4 defines and attributes ‘sessions’ changed fundamentally, and affiliate marketing took a disproportionate hit as a result. Revenue appeared to fall off a cliff, not because performance had dropped, but because the measurement had.
We’ve covered this in a bit more detail before (you can check out the blog here). But the key takeaway is that your analytics dashboard is not the absolute source of truth, and GA4 makes that impossible to ignore.
That was then. What matters now is where we are and where we are heading.
The data quality problem hasn’t gone away. If anything, it’s accelerating. Privacy regulations, rising consent challenges, and the continued decline of third-party cookies mean that conversions are being under-reported across every major platform. The gap between what’s actually happening and what your dashboard tells you is widening and becoming increasingly messy.
And it compounds quickly. Fewer attributed conversions leads to less confidence in a channel. Less confidence means reduced investment, which means less traffic, higher CPCs and CPMs, and budgets squeezed even tighter. Brands caught in this cycle often end up optimising against the wrong signal entirely - cutting spend on channels that are actually working because the data no longer reflects the reality.
This is where server-to-server tracking becomes a non-negotiable.
Unlike browser-based tracking, server-to-server tracking passes conversion data directly between servers, bypassing the browser entirely. It’s not a new concept; the affiliate industry was actually one of its earliest advocates, precisely because accurate attribution has always been fundamental to how the channel works.
When we’ve helped clients fix these foundations, the improvement in reported conversions has almost been immediate. And when data quality improves, everything downstream improves with it. It also unlocks the ability to move beyond basic channel reporting and into sophisticated customer journey analysis, properly understanding how each touchpoint contributed to acquiring then retaining customers.
Understanding the scale of data drop-off you’re currently experiencing in GA4 is also critical. Many brands don’t know how much they’re losing, they’ve simply accepted a lower baseline as the new normal. Auditing that gap and understanding what’s causing it is the first step toward fixing it.
We work with clients across multiple layers of data clarity, combining in-platform metrics, topline revenue and profitability data directly from brands, and attribution tools that sit alongside GA4 rather than relying on it wholesale. It’s a more honest, more sophisticated picture of performance, underpinned by always pushing for the highest quality data we can get our hands on.
As we move through 2026, data is only going to get fuzzier and the customer journey only more complex. The brands that will be best placed to grow are those investing in the right measurement foundations now, interrogating what their data is really telling them, rather than accepting whatever default view their dashboard serves up.
If you're not sure how much data you might be losing or whether your tracking infrastructure is fit for purpose in 2026 and beyond, that’s exactly the kind of conversation we’re here to help. Get in touch today.
