What does the rollout typically involve?

GTM server container on App Engine or Cloud Run, DNS for first‑party endpoint, CMP hookup for Consent Mode v2, CAPI with dedup IDs, and Looker dashboards.

Do we still keep any client‑side tags?

Yes—hybrid is common. We keep lightweight client‑side triggers for consent and event IDs, while routing heavy lifting via the server container.

How do you prove ROI?

We measure event delivery rate, modeled conversions gained, match quality before vs after.

Cloud hosting is usage‑based and modest for most sites. We right‑size architecture and provide cost dashboards so there are no surprises.

Client-Side vs Server-Side - What Actually Changes

Same business questions, different mechanics. Hover to learn more; toggle to see our recommendation by context.

Client-Side

Data Quality

Susceptible to ad-blockers, ITP/ETP; lower event match rates.

Performance

Tags run in browser → scripts add weight; CLS/LCP risk.

Privacy & Control

Harder to enforce governance; PII risks without hashing.

Use Cases

Small sites, low compliance needs, simple pixels.

Server-Side

Data Quality

Higher match rates via CAPI & modeled fills; resilient to blockers.

Performance

Offloads scripts to edge/server → faster pages, better CWV.

Privacy & Control

Hashing, header enrichment, policy filters at the server.

Use Cases

Regulated markets, performance-sensitive sites, multi-channel.

Modeled Conversion Recovery

+10–25%

with Consent Mode v2 + ECL and server-side routing*

Page Performance

LCP −200-500ms

by removing heavy third-party scripts from the browser*

Governance

Policy Filters

strip PII, enforce mappings, and log decisions centrally
