React Next.js Google Tag Manager step by step setup and configuration

Integrating Google Tag Manager into a React Next.js project involves several steps. First, you need to create a Google Tag Manager account and set up a container for your website. Once you have done this, you can add the Google Tag Manager code to your website. Here's how to do it:

1. Create a Google Tag Manager account and set up a container for your website. Follow the instructions provided by Google to create a new account and container. Once you have created the container, you will be provided with a container ID, which you will need to add to your website.

2. Add the Google Tag Manager code to your website. In your React Next.js project, create a new file called google-tag-manager.js in the utils directory. Add the following code to this file:

export const GTM_ID = 'YOUR_GTM_ID';

export const pageview = (url) => {
  window.dataLayer.push({
    event: 'pageview',
    page: url,
  });
};

Replace YOUR_GTM_ID with your actual Google Tag Manager container ID.

3. Add the Google Tag Manager script to your website. In your React Next.js project, open the pages/_document.js file. Add the following code to the Head component:

<Head>
  <script
    dangerouslySetInnerHTML={{
      __html: `
        (function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
        new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
        j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
        'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
        })(window,document,'script','dataLayer',GTM_ID);
      `,
    }}
  />
</Head>

4. Add the Google Tag Manager data layer to your website. In your React Next.js project, open the pages/_app.js file. Add the following code to the componentDidMount method:

import { GTM_ID, pageview } from '../utils/google-tag-manager';

Router.events.on('routeChangeComplete', (url) => pageview(url));

class MyApp extends App {
  componentDidMount() {
    window.dataLayer = window.dataLayer || [];
    pageview(window.location.pathname);
  }

  render() {
    const { Component, pageProps } = this.props;
    return <Component {...pageProps} />;
  }
}

export default MyApp;

This code sets up the Google Tag Manager data layer and sends a pageview event to Google Analytics every time the user navigates to a new page on your website.

By following these steps, you should now have successfully integrated Google Tag Manager into your React Next.js project. You can now start tracking user behavior and gathering valuable insights into your website's performance.

Google Tag Manager configuration options in React Next.js

Here are the Google Tag Manager configuration options for React Next.js integration:

• Container ID: The ID of your Google Tag Manager container. This is a unique identifier that is used to associate your website with your Google Tag Manager account.
• Data Layer: The data layer is a JavaScript object that is used to pass data between your website and Google Tag Manager. It contains information about user behavior, such as pageviews, clicks, and conversions.
• Custom Tags: Custom tags allow you to track specific events or actions on your website. You can create custom tags for things like form submissions, button clicks, and video plays.
• Triggers: Triggers are used to fire tags based on specific events or conditions. For example, you can create a trigger that fires a tag when a user clicks a specific button on your website.
• Variables: Variables are used to capture data from your website and pass it to Google Tag Manager. For example, you can create a variable that captures the value of a form field and passes it to Google Tag Manager when the form is submitted.
• Built-in Tags: Google Tag Manager comes with several built-in tags that allow you to track common events, such as pageviews and clicks. These tags can be customized to suit your specific needs.
• Debug Mode: Debug mode allows you to test your Google Tag Manager implementation and ensure that it is working correctly. When debug mode is enabled, you can see real-time data in the Google Tag Manager interface, which can help you troubleshoot any issues.
