# Install Google Tag Manager Container

Tracking code can be hard to find when it is spread across a site. This guide helps a site owner put the planned tags in a clear place. Start by listing what already runs and what you need to measure.

**The path:** Tag inventory → Container install → Version release → Received-event proof.

**Use this when:** the project has chosen Google Tag Manager for a new measurement setup or a controlled migration from scattered tags.

## Inputs
- The site and measurement plan, existing containers, tags and consent setup. GTM is one implementation option; a valid direct Google tag is not automatically a defect.
- Business-controlled Google Tag Manager access with the permissions needed for the actual create, edit and publish steps, plus supported site-source access.
- A backup or export of the current setup, representative templates and a receiver account for any measurement tag being deployed.

## First-run prompt

> Inspect existing tracking and install or reuse the intended GTM web container within scope. Keep container presence, published version, tag firing and received events separate. Migrate tags only with a controlled duplicate-prevention plan and preserve consent behavior.

## Steps
1. Inventory existing GTM containers, direct tags, plugin integrations and their purposes. Define the intended architecture before adding another container. One clear container per site is a useful default, not a technical rule that valid multi-site or multi-container designs can never exist.
2. Use the existing appropriate business-controlled account and Web container, or create the needed one within the authorized setup scope. Record the account and container IDs and verify actual operator capabilities without granting unnecessary access.
3. Copy the container’s current installation snippets from GTM. Put the script high in the head and the noscript portion just after the opening body tag through the supported theme or platform integration. Avoid duplicate installation across a plugin and template.
4. Save and inspect representative public templates: home, service, post and contact flow. Confirm the intended container ID is present in the served page. Presence proves installation, not that any measurement tag has fired.
5. Add or migrate only the tags in the agreed measurement plan. For each, document trigger, destination, consent requirements and expected event. An empty published container can be correctly installed but provides no measurement by itself.
6. Use Preview and Tag Assistant to inspect tag behavior and consent cases. Preview may run an unpublished workspace. For a migrated tag, coordinate removal of its old source and activation of the new one so the intended event is not lost or sent twice.
7. Publish the reviewed container version when this deployment is authorized. Exit preview and test the ordinary public page against that live version. A current published container may work even when a newer workspace draft remains unpublished; do not confuse the two.
8. Check the intended receiver for each in-scope tag, record version and timestamps, and retain rollback details. If this task only installed an empty container, say so and hand off measurement setup instead of claiming tracking complete.

## Definition of done (QA checklist)

- [ ] The intended container is installed once per intended location or has a documented valid architecture.
- [ ] The normal public page uses the recorded published version; preview evidence is separate.
- [ ] Each in-scope tag has the correct trigger, consent behavior and destination.
- [ ] Tag firing and receiver evidence are checked without unintended duplicate events.
- [ ] Business control, source location, version and remaining measurement work are documented.

## Example(s)

**Fictional teaching example.** A site already has a direct analytics tag. The lesson installs a GTM container and prepares a replacement tag in Preview. That preview pass does not yet prove the public release. At the planned cutover, the direct source is removed and the reviewed GTM version is published. One normal page view then has one matching received event. If the container were published empty instead, the correct result would be “container installed; analytics not configured.”

## Handoff and Content Factory context

Give the container version and architecture record to the measurement owner. Use [set up ga4 with internal traffic filtering](https://local-service-spotlight.github.io/task-library/?task=set-up-ga4-with-internal-traffic-filtering#task-set-up-ga4-with-internal-traffic-filtering) for planned Analytics setup, or [install meta pixel with standard events](https://local-service-spotlight.github.io/task-library/?task=install-meta-pixel-with-standard-events#task-install-meta-pixel-with-standard-events) only when that separate measurement is in scope.

This setup supports the [Content Factory](https://blitzmetrics.com/content-factory/). Produce gathers real source material; Process makes useful assets; Post places and checks them; Promote distributes suitable work within its own scope. This check does not automatically execute all four stages. Use the actual next step above; catalog neighbors are not prerequisites.

## When this runs

Install once and verify after template or tag changes. Future tag releases still need their actual scope, version and event checks; no automatic account access, schedule or universal tag migration is created.

## First-run setup and continuity

Open the supplied task file and its linked source. Verify the project’s real inputs, account, access and output folder before work. This Markdown file is a guide; it does not install an app, connect an account, supply a subscription or create a schedule. Carry out work already authorized; do not ask for the same approval again. Keep any unsupplied destination or new action outside that scope clearly pending.

Save source IDs, versions, decisions, checked outputs and next owner in the project tracker. Before a retry, check the saved state and other workers’ changes. A model name does not guarantee memory or a running timer. Repeated work needs an actual configured trigger and durable state; one-off work can be started by the prompt above.

Keep agent media muted with volume zero before playback. If mute cannot be verified, use captions, metadata or still frames. State the limit: silent visual checks do not prove spoken-word accuracy or audio quality. Do not start sound through the user’s speakers unless explicitly asked.

## Write up the real run

For every actual attempt, [write its meta article](https://blitzmetrics.com/meta-article-prompt/) with this recipe and revision, trigger, steps performed, output evidence, measured result, gaps and next owner. Failed, blocked and partial attempts also get a written record. A draft can satisfy writing; publishing it follows the existing job scope.

Keep one stable execution ID across retries and edits. A separately scoped child task may have its own ID linked to its parent. Writing the parent’s meta record is part of that run, not an endless new chain. The [recipe and meta-article guide](https://localservicespotlight.com/meta-articles/) explains this distinction. Teaching examples are not real executions and must not enter the run count.


<!-- factory-layer:start -->

## Factory chain (do not treat this as isolated)

- **Phase:** Gate
- **Importance:** 5/5 `●●●●●` — frequency 4, revenue 5, gating 5 (runs every factory cycle or weekly; ads/revenue path; unblocks a chain (access/plumbing))
- **Suggested previous station:** `set-up-content-library`
- **Suggested next station:** `set-up-ga4-with-internal-traffic-filtering`
These stations are generated neighbors, not verified prerequisites or handoffs. Follow the task’s actual Inputs and Handoff sections.
- **Handoff:** Record only the property IDs, access and checks required by this task in the client register. Pass the verified result to the task that needs it.

## Model routing (same factory, any engine)

- **This task's lane:** `computer` — Logged-in UI (Meta Ads Manager, Descript, GSC, wp-admin when REST is blocked). Requires a supported browser tool and the right account access.
- **Single-engine path:** Use the capable AI app you already have. Check its required tools and access before starting. Pass the actual result and proof to the next task.
- **Optional multi-engine:** A tested local model may draft; a stronger model may review facts and voice. Use supported tools for approved actions. Pick models from observed quality and cost; a model name does not prove it can run this task.
- **Never** store the working state in one vendor's memory. Files in the Content Library are the bridge.

## Review and evidence still needed

The source contributor status is preserved. It is not certification of this draft or proof of account access, completed work or a live outcome. The worked example teaches the method and is explicitly fictional.
- Source status remains gap and the dedicated task article is missing. The historical client anecdote is not proof for a new install; actual version and receiver evidence are still required.
