Every major ad platform now runs its own automated bidding system, trained on its own data, optimising for its own definition of success. That is fine in isolation. Run four or five of these systems side by side with no coordination, and each one will quietly compete with the others for the same customer, confidently and at scale, because none of them can see what the others are doing.
Privacy changes have made this worse, not better. As cross-device and cross-platform tracking gets harder, platforms increasingly fall back to self-reported, in-platform attribution, which means every dashboard tells an increasingly flattering and increasingly incomplete story. The businesses that avoid wasting budget on duplicated effort are the ones measuring the portfolio from outside any single platform’s reporting, not inside it.
AI-driven creative tools have also lowered the cost of testing on every platform at once, which sounds like an advantage until a brand is running a dozen uncoordinated tests simultaneously with no shared hypothesis behind any of them. The advantage only compounds when testing is coordinated against one plan, so what is learned on one platform actually informs what gets tried on the next.
None of this requires abandoning any platform. It requires a layer above them: one plan, one attribution model, and a weekly habit of asking whether the portfolio, not any single account, is moving in the right direction.
