There is a growing rebellion happening in paid media. Not the loud kind. The kind where senior marketers quietly start moving budgets.
Google's Performance Max, Meta's Advantage+ and The Trade Desk's programmatic stack all share a common pitch: let the algorithm handle it. Feed the machine your creative, set a budget, trust the output.
The problem? Trust requires transparency. And transparency is exactly what these platforms are stripping away.
A Digiday investigation published this week surfaced what many agency leaders have been saying privately for months. PMax campaigns deliver aggregated results with minimal breakdown by placement, audience or creative. Brands know their money is being spent. They don't know where, or why.
Meta's Advantage+ has a different flavour of the same issue. Default settings quietly expand targeting, override manual audience selections and blend prospecting with retargeting in ways that make attribution nearly impossible. One agency exec described finding that Advantage+ had silently toggled on settings they had explicitly turned off.
The Trade Desk, long positioned as the transparent alternative to walled gardens, is now facing its own scrutiny. Its Kokai platform adds AI-driven optimisation layers that, while effective in some cases, reduce the control that sophisticated buyers expect.

For Australian businesses spending $20K or more per month on paid media, this matters. A lot.
When you can't see which placements drove conversions, you can't optimise creatively. When audience controls get overridden silently, you can't build reliable customer acquisition models. When attribution gets blended, you can't calculate true cost per acquisition.
The response from platforms has been predictable: more automation, more AI, more promises that the machine knows best.
But the best-performing brands we see in our benchmark data aren't the ones blindly trusting algorithms. They're the ones running parallel manual campaigns alongside automated ones, comparing results and holding platforms accountable with first-party data.
The brands winning in paid media aren't fighting automation. They're auditing it.
Three things every marketing team should be doing right now. First, run at least one manual campaign per platform alongside your automated campaigns. If PMax outperforms a well-structured manual campaign by more than 30%, something is probably wrong with your manual setup, not right with PMax. Second, check your Advantage+ settings weekly. Meta has a pattern of resetting configurations during updates. Third, demand placement-level reporting from every platform. If they can't provide it, that's a data point in itself.
The platforms aren't going to voluntarily give control back. The brands that maintain it are the ones who never fully gave it away.
