Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureSince 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.
PixelRelay sends your Shopify events server-to-server — orders, add to carts, checkout starts, and more — to Google Ads, Meta, TikTok, GA4, Bing, and Segment, with more integrations coming. Captures conversion data browser-based pixels often miss due to ad blockers, iOS, and cookie restrictions. Includes Enhanced Conversions, click ID capture, GDPR Consent Mode v2, and event deduplication.
- Headline tracking-health score (0-100): healthy / needs-work / at-risk

- Prioritized, money-framed findings with the exact fix for each gap
- Server-side tracking that bypasses ad blockers, iOS & cookie blockers
- Sends events server-side to Google Ads, Meta, TikTok, GA4, Bing, and Segment
- Order webhooks catch every purchase — even when browser pixels are blocked
- Enhanced Conversions with auto-capture of GCLID, FBCLID, TTCLID & MSCLKID
