Why Social Campaigns Decay — and What Prevents It
Social advertising fails differently from search. The audience is not looking for you, so the creative carries the entire burden of earning attention. That creative wears out, and performance decays whether or not anything else changed. The fix is systematic rotation, not a bigger budget.
The second issue is measurement loss. Browser-based tracking misses a meaningful share of conversions to ad blockers and privacy controls, which starves optimisation of the signal it needs. Server-side measurement restores enough of that picture for the platform to bid sensibly.
