Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureManual pixel code misses sales and breaks when themes change. Nabu installs your Facebook pixel and Instagram pixels in 1 click, with no theme edits. The Meta Conversions API sends server events past iOS 14 limits, Meta pixel deduplication counts each order once and advanced matching improves Meta event matching.
Since iOS 14.5, many conversions go unmatched to Meta/Google. Pixel Proof doesn't install a pixel; it audits the server-side tracking you run and scores what decides whether conversions match: CAPI coverage, event_id dedup, and match-key completeness (an EMQ proxy). You get a health score (0-100), a per-key coverage chart weakest-first, and a prioritized, money-framed fix list.
