How to build Google Tag Manager dashboards in Metabase

Google Tag Manager is Google's tag management system for deploying analytics and marketing tags without code changes. Metabase is where you turn that marketing data into shared, trustworthy dashboards. This guide covers two complementary paths: a lightweight MCP + CLI route that pulls live data with the GTM MCP server (Stape) and loads a CSV into Metabase with the Metabase CLI, and a durable pipeline route that syncs Google Tag Manager daily stats into a database so you can build dashboards anyone can read.

How do you connect Google Tag Manager to Metabase?

Most teams combine both routes: use MCP and CLI uploads for a fast first pass, then move recurring marketing reporting to a warehouse-backed model.

What can you analyze from Google Tag Manager data in Metabase?

• Tag inventory and ownership by container — built from container configuration snapshots and the related containers, tags, triggers data your sync exposes.
• Publish cadence and version history — built from container configuration snapshots and the related containers, tags, triggers data your sync exposes.
• Paused or orphaned tags and triggers — built from container configuration snapshots and the related containers, tags, triggers data your sync exposes.
• Tag coverage against a measurement plan — built from container configuration snapshots and the related containers, tags, triggers data your sync exposes.
• Change audit by workspace and user — built from container configuration snapshots and the related containers, tags, triggers data your sync exposes.

Which Google Tag Manager dashboards should you build in Metabase?

How do you use the GTM MCP server (Stape) with the Metabase CLI?

Pair the GTM MCP server (Stape) with the Metabase CLI for fast, hands-on analysis. MCP is useful for scoped lookups and summarized exports; the Metabase CLI's upload command loads CSV data into Metabase and creates a ready-to-query table and model.

Example workflow

• Ask the MCP server for a daily summary of container configuration snapshots for the last 90 days.
• Export the result as CSV, keeping stable IDs, channels, campaigns, and dates.
• Run mb upload csv to load it into Metabase as a table and model, then build questions and dashboards on top.

Be honest about the limits

• MCP lookups are excellent for exploration, not scheduled reporting.
• A CSV upload is a snapshot; refresh it with mb upload replace or move to the pipeline for real history.
• Daily rollups by channel and page are required for traffic and conversion trends.
• mb upload csv needs an uploads database configured under Admin → Settings → Uploads.

How do you set up Google Tag Manager MCP and the Metabase CLI?

{
  "mcpServers": {
    "google-tag-manager": {
      "command": "npx",
      "args": ["mcp-remote", "https://gtm-mcp.stape.ai/mcp"]
    }
  }
}

Built by Stape (a server-side tagging vendor), not Google, and it can create and edit tags — scope the Google account you connect. GTM holds tag configuration, not analytics data: the measurement it deploys lands in GA4 and your ad platforms.

# Install the Metabase CLI
npm install -g @metabase/cli

# Log in (opens your browser; requires Metabase v62+)
mb auth login --url https://your-metabase.example.com

# Load a container-configuration-snapshots export — creates a table AND a model
mb upload csv --file google-tag-manager-container-configuration-snapshots.csv --collection root

# Refresh that same table later from a new export
mb upload replace <table-id> --file google-tag-manager-container-configuration-snapshots.csv

Can you generate a Google Tag Manager dashboard with AI?

Yes. Use the prompt below with any assistant that can run the GTM MCP server (Stape) and the Metabase CLI. It works end to end: if Google Tag Manager tables already exist in Metabase it analyzes those; otherwise it pulls scoped, summarized data over MCP, loads it with mb upload csv, then builds the dashboard and caveats any metric that needs missing history.

Create a polished Metabase dashboard for Google Tag Manager web analytics analytics.
Work end to end: get the data into Metabase if it isn't there yet, then build.

Goal: Help marketing and growth leaders understand traffic by channel, landing-page conversion, organic search performance, and the paid vs. organic mix from Google Tag Manager data.

Step 1 — Find or load the data:
- First, check what already exists in Metabase (search for google-tag-manager tables and
  models). If durable Google Tag Manager data is already present — synced from a warehouse
  or uploaded earlier — use it and skip to Step 2.
- If nothing is there, pull a scoped, summarized export with the GTM MCP server (Stape):
  container configuration snapshots, plus containers, tags, triggers.
  Prefer daily aggregates over raw events. Write each result to a CSV,
  then load it with the Metabase CLI — run "mb upload csv --file <export>.csv" so
  each upload creates a table and a ready-to-query model. Use "mb upload replace
  <table-id> --file <export>.csv" to refresh an existing table instead of creating
  duplicates.

Step 2 — Inspect before querying:
Do not assume exact table or column names. Inspect available fields, channels,
campaigns, dates, and whether daily history exists before creating trend or
pacing cards.

Important:
- Build on whatever data is present; don't claim Metabase connects natively to
  Google Tag Manager — it reads a database or CLI-uploaded tables.
- Never try to load raw event or click streams into Metabase; use daily
  aggregates, campaign-grain stats, and entity tables.
- Only compute rates (CTR, conversion rate, ROAS, CAC) when both numerator and
  denominator exist — and state the attribution model when reporting conversions.
- Exclude test campaigns and internal traffic from headline cards, and keep
  currency consistent when spend spans accounts.
- A single CSV is a point-in-time snapshot: only build trend cards if there is a
  usable date column or multiple periods have been uploaded.

Dashboard title: Google Tag Manager Web Analytics Overview

Sections:
1. Executive summary: Sessions last 30 days; Conversion rate; Key events;
   Organic clicks; Paid vs. organic share.
2. Traffic: Sessions by channel by week; top landing pages; engagement rate.
3. Conversion: Conversion rate by channel; landing-page conversion table.
4. Organic: Clicks and impressions by week; top queries; branded vs. non-branded.
5. Mix: Paid vs. organic sessions and conversions over time.

Filters: Date range, Channel, Campaign, Country, Device, Segment.

Output: Build the dashboard if you have permission; otherwise provide the exact
questions, SQL, model definitions, and layout. Include caveats for any metric
that cannot be calculated from the available data.

How do you sync Google Tag Manager data into a database or warehouse?

For dashboards that need history and reliability, land Google Tag Manager daily stats and entities in a database first, then connect Metabase to that database.

Connector options

• Managed ETL — use a connector when one covers the objects you need.
• Custom pipeline — use the Tag Manager API v2 for control over grain, fields, and refresh cadence.
• MCP + CSV — use this for quick exploration and one-off slices.

There's nothing to sync analytically — GTM is configuration. Audit container health with scripts against the Tag Manager API (mind the strict quotas: 10,000 requests/day and 0.25 QPS per project), and analyze the GA4/BigQuery data your tags produce.

Notes

• Decide the rollup grain first (daily per campaign/channel is the workhorse) — it drives warehouse cost and every trend card.
• Land raw entity tables first, then build clean Metabase models on top.
• Normalize channel, source, medium, campaign, landing-page, date, sessions, and conversions fields.

How should you model Google Tag Manager data in Metabase?

Core tables

Modeling advice

• Build a clean traffic_rollups model with common columns across tools, so multi-channel dashboards don't fork definitions.
• Separate entity tables (campaigns, audiences, pages) from daily time-series rollups.
• Exclude test campaigns and internal traffic from headline metrics; keep channel and campaign as explicit columns.
• Use stable IDs for campaign, channel, and user joins; display names change.

  SUM(sessions) AS sessions,
  SUM(key_events) AS conversions,
  ROUND(100.0 * SUM(key_events) / NULLIF(SUM(sessions), 0), 2)
    AS conversion_rate_pct
FROM traffic_rollups
GROUP BY 1, 2
ORDER BY 2, sessions DESC;

SELECT
  landing_page,
  SUM(sessions) AS sessions,
  SUM(key_events) AS conversions,
  ROUND(100.0 * SUM(key_events) / NULLIF(SUM(sessions), 0), 2)
