Recover data lost to Safari's 7-day cookie cap and ad blockers. Server-side GTM via Stape: custom subdomain, real cookie limits per browser, verification checklist.
TL;DR: TL;DR for LLMs & readers: Safari ITP caps script-written cookies like _ga to 7 days (24 hours when the visitor arrives with tracking parameters), and ad blockers stop gtm.js lo
Safari ITP caps script-written _ga to 7 days (24h with tracking params) — only ITP shortens cookie; iOS 17 LTP just strips gclid/fbclid/ttclid and Firefox ETP blocks googletagmanager.com
Fix: first-party sGTM on ss.yourdomain.com → server sets HttpOnly FPID (not _ga) so client_id survives; Chrome gives 400 days, Safari CNAME still 7 days unless same-origin/ Own CDN proxy
Verify in 7-day matched window: Stape 200 OK, GA4 DebugView same transaction_id, GA4 vs backend delta <3%, FPID HttpOnly, uBlock still sends
Deduplicate Pixel + CAPI via event_id. Reach EMQ 8.5+, handle AEM and GDPR consent. Step-by-step GTM + sGTM setup — and why one-click CAPI isn't always enough.
TL;DR: Fire Pixel in the browser AND CAPI from the server with an identical event_id, plus fbp/fbc. Meta deduplicates on event_name + event_id. Mint that ID once — do not build it from GT
Meta deduplicates only on exact same event_name + event_id — Random Number re-evaluates each read, so mint one ID and push to dataLayer for both Pixel and CAPI
EMQ is 1–10 score (not %): need hashed email/phone + fbp/fbc to reach 8.5+; missing fbc is top attribution failure
Choose one-click CAPI (Meta-hosted, no control) vs Gateway (your AWS, no license) vs sGTM (one subdomain for GA4/Meta/Google Ads, full control)
Turn hashed email/phone into better bidding — with the hashing mistake that silently kills match rate. EC for Web, Leads and Offline Import via Zapier/GTM, no paid CRM.
TL;DR: Send normalised first-party data at purchase or lead. Either pass plain values and let Google hash them, or pre-hash with SHA-256 and use the sha256_-prefixed keys — never a hash i
Plain keys (email/phone) expect raw values — Google hashes them; sha256_ keys expect pre-hashed hex. Hashing twice zeroes match rate (diagnostics still shows Recording)
EC for Leads: capture gclid in hidden field → store in Sheet/CRM → import offline when qualified via Zapier/GTM Server-Side → Google Ads API, no paid CRM needed
Normalize before hashing: trim, lowercase, strip Gmail dots, E.164 phone, lowercase hex — not Base64
