# Google Analytics 4

With JENTIS, you have multiple options to integrate **Google Analytics 4 (GA4)** depending on your organization’s requirements. This flexibility caters to all stakeholders — from data privacy officers to online marketers.

You can decide whether to execute GA4 tracking **client-side, server-side, or in a hybrid model**, and easily migrate between them as your setup evolves.

### GA4 Options with JENTIS Data Capturing Platform

Choose one of the following options to leverage GA4 with JENTIS:

#### 1. Client-Side Execution

JENTIS acts as the **frontend tag management solution** that loads the Google Tag (`gtag.js`) and provides it with your configured data.

* Full GA4 feature set available (marketing tools, automatic event tracking, conversion flagging, etc.).
* Managed directly in the GA4 interface.

#### 2. Server-Side Execution via Measurement Protocol v2

Send data via the official **GA4 Measurement Protocol** to your GA4 instance.

* Best used to **augment** client-side data collection.
* Reference: [GA4 Measurement Protocol v2](https://developers.google.com/analytics/devguides/collection/protocol/ga4).

#### 3. Server-Side Execution via JENTIS TWIN Browser

The **JENTIS TWIN Browser** computes the data stream server-side in a way similar to how `gtag.js` would execute in the browser.

* Offers all the **privacy and data quality benefits** of server-side tracking.
* Extends capabilities beyond Measurement Protocol (which can only augment).

### GA4 Tools in JENTIS

Because GA4 offers significantly different implementation methods, JENTIS provides **two distinct GA4 Tools** in the Data Capturing Platform (DCP):

* **GA4**
  * Includes client-side `gtag.js` integration and Measurement Protocol.
* **GA4 Server-Side**
  * New tool dedicated exclusively to server-side tagging.
  * Includes templates for Pageview, Custom Events, E-commerce, etc.
  * All future JENTIS GA4 server-side developments will be available here.
