This guide walks your technical or marketing team step-by-step through installing the MGID Server-Side Google Tag Manager (GTM) template into a GTM Server Container. With this template, advertisers experience more reliable attribution, improved privacy compliance and fewer ad-blocking issues.
### Stage 1: Preparation (what the advertiser must do first)
Before installing the template, please ensure the following items are in place.
1\. A **GTM Server Container** (App Engine or Cloud Run) is required to use the MGID server-side GTM template.
Review the Tag Manager instruction: [Set up a server container](https://developers.google.com/tag-platform/tag-manager/server-side)
2\. Map the Server Container to a **same-site subdomain** of your website (example: gtm-server.example.com for example.com). Note that cookies set from a different domain are considered third-party cookies and will be blocked.
Review the Tag Manager instruction: [Map a custom domain](https://developers.google.com/tag-platform/tag-manager/server-side/custom-domain)
3\. Grant **publish permission** toensure the person setting up the Server Container also has permission to publish it.
### Stage 2: MGID Template Configuration and Installation
##### Stage 2.1. Page view tag: Capture Click ID on arrival
This tag ensures the Click ID is stored immediately upon arrival. To set up the Page view tag, follow these steps:
1. In the Server Container, create a **New Tag** and select **MGID Server-Side Tag**.
2. Set **Event Type** to **PageView**.
3. **Triggering:** Fire on **All Page Views**.
4. **Save** as "MGID - PageView".
##### Stage 2.2. Conversion tag: Send conversions back to MGID
This tag sends the data back to MGID. To set up the Conversion tag, follow these steps:
1. In the Server Container, create a **New Tag** and select **MGID Server-Side Tag**.
2. Set **Event Type** to Conversion.
3. Enter the **Event Name** (or example purchase). **Note:** Use only Latin letters, numbers, hyphens and underscores.
4. (Optional) Map a **Conversion Value**.
5. **Triggering:** Fire on your conversion event (e.g., **Event Name equals purchase**).
6. **Save** as "MGID - Conversion".
### Stage 3: Verification (before publishing)
Before you publish, validate the setup in Server Preview:
1. In the GTM Server Container, click **Preview** to open the Server Debugger.
2. In the browser, simulate page visits and conversion flows (example: visit https://example.com/?adclid=test).
3. In Server Debugger:
- Confirm **PageView** request arrived and **MGID PageView** fired.
- Confirm a cookie named **MgidSensorClid** was set.
- Confirm **Conversion** request fired and an outgoing request to https://a.mgid.com/postback returned **200**.
- Check template console logs for success/error messages (e.g., “Click ID found in page\_location”, or “ERROR: Click ID is required…”).
Review the Tag Manager instruction: [Server-side Preview Mode Guide](https://developers.google.com/tag-platform/tag-manager/server-side/debug)
