N/A
Client-side can't reliably deliver product-level payloads
Advanced
Cart data via sGTM, catalog matching on server. Requires clean product feed as prerequisite.
Google: items[] + Merchant Center
Meta: contents[] + Commerce Mgr
Advanced
Gateway-enriched product events. Auto-catalog matching at the infrastructure layer.
Signals Gateway + BigQuery
sGTM + Stape
FRONTIER
Frontier
Enriched multi-source events through sovereign infrastructure. LTV, margin, subscription status attached before routing.
Full sGTM + CRM enrichment
CDP + reverse ETL pipeline
N/A
Identity enrichment requires server-side infrastructure
SWEET SPOT
Best Practice
Current gold standard. sGTM with Enhanced Conversions, CAPI with Advanced Matching + external_id.
EMQ target: 8.0+
EC match target: 50%+
SWEET SPOT
Best Practice
Gateway-managed identity with first-party cookies. Automatic dedup. Extended cookie lifetime via first-party domain.
Signals Gateway + Signals Pixel
Google Tag Gateway + sGTM
Leading Edge
Centralized identity strategy. One external_id, not per-platform cookies. Cross-device resolution at the routing layer.
Consent enforced once at hub
Identity persists across sessions
Common
Browser-side hashed PII. Still subject to ad blocker and ITP restrictions. EC enabled ≠ EC working well.
Google: Enhanced Conversions
Meta: Advanced Matching (Pixel)
Growing
Server-side hashed PII with proper normalization. Dedup via event_id/transaction_id. Early sGTM adopters.
CAPI + Pixel redundant events
sGTM + Enhanced Conversions
Emerging
Gateway auto-captures and hashes PII. First-party context improves match rates. Simplified setup vs. manual sGTM.
CAPI Gateway (Meta-only)
Tag Gateway (Google-only)
Rare
Full data hub for L2 measurement is over-engineered. Move to L3+ measurement first.
MOST COS
Most Advertisers
Default starting point. gtag.js or Meta Pixel firing on conversion page. 30-50% signal loss from ad blockers + privacy.
Google: gtag.js / GTM web
Meta: fbevents.js
Rare
Server infra without enhanced matching = wasted capability. Move to L2 measurement first.
N/A
Gateway without measurement maturity is infrastructure without purpose
N/A
Data hub without measurement maturity is over-architecture
