# Google Analytics

Integrating **Google Analytics (GA4)** allows you to track how visitors interact with your site. It helps you understand where your users come from, which steps of your quiz they complete, and where they drop off before making a purchase. By using this data, you can improve your sales funnel and increase your conversion rates.

## Integration Steps

1. **Open Integrations:** In your Zotlo panel, click the **"Integrations"** tab in the side menu.
2. **Select Google Analytics:** Find Google Analytics in the list.
3. **Enter your ID:** Paste your code into the **GA4  ID** field and save.

## **GA4 Measurement ID**

* It is a unique identifier (format: `G-XXXXXXXXXX`) that tells Google where to send your website's data.
* **Where to find it**

   1\. Log in to your [Google Analytics](https://analytics.google.com/) account. \
  2\. Go to **Admin** > **Data Streams**. \
  3\. Select your website stream. \
  4\. Copy the **Measurement ID** from the top right corner.
