The only checklist you need to audit any Facebook ads account in 2026. Ten ordered sections, yes-or-no checks, progress saves automatically to this browser. Read the checklist guide for the structural explanation behind each section.
The checks are ordered for a reason. Fix in this priority, regardless of where the leaks live: any failure in section 2 (Pixel and CAPI) blocks everything else. Then section 7 (cross-platform). Then section 5 (account stage). Then section 6 (budget). The other sections are quality-of-life fixes. Read the full fix-order section of the guide.
