# Google Tag Manager (GTM)

If you prefer not to modify your storefront templates directly, you can load the Experro Analytics SDK via Google Tag Manager (GTM). This is convenient for teams that manage scripts centrally through GTM, though note that tag managers can be blocked by some ad blockers.

### Prerequisites

* Access to your site’s GTM container (web)
* Your Experro Analytics configuration values (tenant, workspace, environment, channel, etc.)

### Step-by-Step: Install the SDK via GTM

1. **Sign in to GTM**\
   Go to [tagmanager.google.com](https://tagmanager.google.com), and open the appropriate **Account** and **Container** (Workspace) for your site.

2. **Create a new Tag**
   * In the left-hand navigation, click **Tags**.
   * Click **New** → **Tag Configuration**.
   * Choose **Custom HTML** as the tag type.

3. **Add the Experro SDK snippet**\
   In the **HTML** text area, paste the Experro SDK snippet, for example:

   ```html theme={null}
   <script defer src="https://experro-pov.myexperro.com/experro-analytics-library/CUSTOM_JS_SDK_NAME.js"></script>
   ```

   Adjust the configuration values (`YOUR_TENANT_ID`, `YOUR_WORKSPACE_ID`, etc.) to match your environment.

4. **Configure tag advanced options**
   * Leave **Support document.write** unchecked/blank.
   * Under **Advanced Settings**, set **Tag firing options** to **Once per page**.
   * Leave other advanced settings at their defaults.
   * Give your tag a descriptive name, for example: `Experro Analytics SDK`.

5. **Create a Trigger**
   * In the left-hand navigation, click **Triggers** → **New**.
   * Click **Trigger Configuration** and choose **DOM Ready** (or **All Pages** if preferred).
   * Leave other options as their defaults.
   * Name the trigger, for example: `Experro SDK – DOM Ready`.

6. **Associate the Tag with the Trigger**
   * Go back to your **Experro Analytics SDK** tag.
   * Under **Triggering**, select the trigger you just created (`Experro SDK – DOM Ready`).

7. **Publish the container**
   * Click **Submit** → add a version description if desired → **Publish**.

Once published, GTM will load the Experro Analytics SDK on every page where the trigger conditions are met.

> **Note:** Loading the SDK via GTM is convenient but can be affected by ad blockers or script restrictions. For maximum data quality and coverage, Script Injection is still recommended for production environments.
