The browser pixel loses up to 30% of your conversions
iOS restrictions, ad blockers and third-party cookie removal drop events before they ever reach Facebook. The algorithm optimizes on partial data — and you pay for it with a rising cost per result.
Blind optimization
Facebook misses purchases and leads → worse audience targeting.
Broken attribution
Reports understate real results, decisions are made in the dark.
Expensive leads
Fewer signals → higher CPA on the same budget.
A live stream of your events — from source to Ads Manager.
