Replaces volatile 7-day Safari ITP JavaScript cookies with server-set `HttpOnly; Secure; Max-Age=31536000` cookies. - **100% Client Asset Ownership & Zero SaaS Tax**: Built directly inside the client's own Google Tag Manager, Google Cloud, and Cloudflare accounts. Zero vendor lock-in and $0/month SaaS middleware tax (unlike Elevar, Stape, or TripleWhale). - **Zero-Developer Friction Delivery**: 100% turnkey external deployment via GTM container synchronization and DNS routing, requiring 0 developer hours from internal engineering teams. ### Core 02: Dual-Rail Meta CAPI v22.0 (`8.0+ Purchase EMQ`) & Google Enhanced Conversions - **Deterministic Browser + Server CAPI Deduplication**: Shared `event_id` synchronization across Web GTM and Server GTM (`0.0%` duplicate conversions). - **7-Point SHA-256 Checkout Hashing (`8.0+ Purchase EMQ Guarantee`)**: Normalizes and hashes `em`, `ph` (E.164), `fn`, `ln`, `ct`, `zp`, `_fbp`, `_fbc`, `client_ip_address`, and `client_user_agent` at checkout to achieve `8.0+ Meta Purchase EMQ` (verified live benchmark: `Purchase: 9.3/10`, while anonymous top-of-funnel `PageView`/`ViewContent` events naturally score `6.2–6.8/10`). - **Google Ads Enhanced Conversions & Consent Mode v2**: Full server-side Enhanced Conversions (`gclid`/`gbraid`/`wbraid`) and GDPR/DMA-compliant Google Consent Mode v2 (`ad_storage`, `ad_user_data`, `ad_personalization`, `analytics_storage`). ### Optional Phase-2 Add-Ons (Scoped & Priced Separately Only Upon Client Request) - **GMC Supplemental Feed Engineering**: 150-character product title structuring and `custom_label_0..4` hydration via non-destructive Supplemental Feeds. - **24/7 Google Ads Guard Scripts**: Read-only search term anomaly alerts, account-level placement exclusions, and HTTP 404 landing page checks. - **Stacked JSON-LD Schema & `llms.txt` (AEO/GEO)**: Entity graph markup (`Organization`, `Product`, `FAQPage`) and `llms.txt` endpoints for AI search citation. ## Verified Production Telemetry Benchmarks - **Meta `Purchase` Event Match Quality (EMQ)**: Surges from 4.4/10 to a verified 9.3/10 (`Purchase: 9.3/10`, `InitiateCheckout: 6.8/10`, `AddToCart: 6.5/10`, `ViewContent: 6.2/10`, `PageView: 6.2/10`). - **1st-Party Cookie Persistence on iOS Safari**: Extended from 7 days (24h with link decoration) to 365 days (`Max-Age=31536000; HttpOnly; Secure`). - **Attributed Conversion & Revenue Recovery**: +34.8% to +38.4% additional tracked purchase revenue captured. ## The 3 Ironclad Delivery Guarantees 1. **Zero-Dev Guarantee**: 100% turnkey delivery executed end-to-end by senior tracking engineers with 0 developer hours required from client teams. 2. **8.0+ Meta Purchase EMQ Guarantee**: Guaranteed 8.0+ `Purchase` Event Match Quality achieved and empirically verified in Meta Events Manager upon turnkey deployment—or we work free until hit. 3. **Zero Checkout Downtime Guarantee**: 100% fail-safe ES5 JavaScript execution with silent error degradation, guaranteeing zero disruption to store checkouts. ## Diagnostic & Audit Ingestion Endpoint - **Action**: Request a Free 15-Point Live DevTools & Telemetry Video Diagnostic - **Turnaround**: Delivered within 48 hours via video-recorded Chrome DevTools network inspection. - **Official Contact Email**: contact@omniscaledatalabs.com - **Contact / Audit Form**: https://omniscaledatalabs.com/#contact - **Last Synchronized**: 2026-10-17
