To add Google Analytics to a Next.js application, you need to follow these steps:
- Set up a Google Analytics account: Go to the Google Analytics website, sign in with your Google account, and set up a new property for your Next.js application. Note down the tracking ID that Google provides.
- Install the required packages: In your Next.js project, open the terminal and run the following command to install two necessary packages: npm install react-ga next-ga
- Create a utility file: In your Next.js project, create a new file (e.g., utils/analytics.js) and add the following code: import ReactGA from 'react-ga'; export const initGA = () => { ReactGA.initialize('YOUR_TRACKING_ID'); }; export const logPageView = () => { ReactGA.set({ page: window.location.pathname }); ReactGA.pageview(window.location.pathname); }; Replace 'YOUR_TRACKING_ID' with the tracking ID you obtained from Google Analytics.
- Import and use the utility in the _app.js file: Open the _app.js file in your Next.js project and add the following code: import { useEffect } from 'react'; import { initGA, logPageView } from '../utils/analytics'; const MyApp = ({ Component, pageProps }) => { useEffect(() => { initGA(); logPageView(); }, []); return ; }; export default MyApp;
- Configure Next.js to load the utility on every page: In your Next.js project, create a new file next.config.js (if not already present) and add the following code: module.exports = { webpack: (config, { isServer }) => { if (!isServer) { config.node = { fs: 'empty', }; } return config; }, }; This ensures that the utility can be properly used on the client-side.
- Implement event tracking (optional): To track events like button clicks, form submissions, or other user interactions, modify the utils/analytics.js file to include appropriate functions (e.g., logEvent). Then, call those functions wherever you want to track such events in your Next.js components.
That's it! By following these steps, you can add Google Analytics tracking to your Next.js application and gather valuable insights about your users' activities.

Is it difficult to add Google Analytics to Next.js?
Adding Google Analytics to Next.js can be relatively easy. Next.js provides a way to have dynamic imports of external JavaScript libraries in its Head component. This can be used to load the Google Analytics script dynamically and add the necessary tracking code to your Next.js application.
Below is an example of how to add Google Analytics to a Next.js application:
- Install react-ga package by running the following command:
1
|
npm install react-ga
|
- Create a new file called analytics.js in the lib directory (you may need to create this directory):
1 2 3 4 5 6 7 8 9 10 11 12 |
// lib/analytics.js import ReactGA from 'react-ga'; export const initGA = () => { ReactGA.initialize('UA-XXXXXXXX-X'); // Replace with your own tracking ID }; export const logPageView = () => { ReactGA.set({ page: window.location.pathname }); ReactGA.pageview(window.location.pathname); }; |
- Modify the _document.js file in your Next.js application's pages directory:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 |
// pages/_document.js import Document, { Html, Head, Main, NextScript } from 'next/document'; import { initGA, logPageView } from '../lib/analytics'; class MyDocument extends Document { componentDidMount() { initGA(); logPageView(); } render() { return ( <Html> <Head> {/* Add your own Head contents here */} <script async src="https://www.google-analytics.com/analytics.js" /> </Head> <body> <Main /> <NextScript /> </body> </Html> ); } } export default MyDocument; |
- The setup is now complete. Google Analytics will now track page views on your Next.js application.
Note: Remember to replace 'UA-XXXXXXXX-X' with your own Google Analytics tracking ID.
Adding additional tracking events or customizing Google Analytics can be done by importing and using the ReactGA object from the analytics.js file in your components as needed.
Overall, integrating Google Analytics into Next.js is not difficult and can be achieved by following the steps above.
How can I verify if Google Analytics is properly added to my Next.js website?
To verify if Google Analytics is properly added to your Next.js website, you can follow these steps:
- Go to your website in a web browser and open the developer tools. You can do this by right-clicking anywhere on the page and selecting "Inspect" or "Inspect Element".
- In the developer tools panel, navigate to the "Network" tab.
- Refresh the page to trigger any network requests.
- Look for a request with the name "collect" or "analytics.js" or "ga.js". These requests indicate that Google Analytics is sending data to the Google servers.
- If you find any of these requests, it means that Google Analytics is properly added and tracking data from your website.
Alternatively, you can also check the source code of your website to verify if the Google Analytics tracking code is present.
- Open the source code of your website. You can do this by right-clicking anywhere on the page and selecting "View Page Source" or by using the developer tools.
- Search for "UA-" followed by a string of numbers. This is the tracking ID used by Google Analytics.
- If you find this tracking ID in the source code, it means that Google Analytics is properly added to your Next.js website.
By following these steps, you can verify if Google Analytics is successfully integrated into your Next.js website.
Can I use Google Analytics to track user engagement on specific components in Next.js?
Yes, you can use Google Analytics to track user engagement on specific components in Next.js.
To implement this, you would typically use custom events or virtual pageviews to track user interactions on specific components.
For example, if you have a component for a button, you can use the Google Analytics event tracking feature to track when users click on that button. You would need to add a tracking event code to the button's onClick handler.
Here's an example code snippet to give you an idea:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 |
import { useEffect } from 'react'; import { useRouter } from 'next/router'; const MyButtonComponent = () => { const router = useRouter(); const handleButtonClick = () => { // Track the button click event window.gtag('event', 'button_click', { event_category: 'engagement', event_label: 'My Button Component', }); // Redirect to another page router.push('/another-page'); }; useEffect(() => { // Load the Google Analytics script window.dataLayer = window.dataLayer || []; function gtag() { dataLayer.push(arguments); } gtag('js', new Date()); gtag('config', 'YOUR_ANALYTICS_TRACKING_ID'); }, []); return ( <button onClick={handleButtonClick}> My Button </button> ); }; export default MyButtonComponent; |
Remember to replace 'YOUR_ANALYTICS_TRACKING_ID' with your actual Google Analytics tracking ID.
With this implementation, you will be able to track the user engagement on the specific component and view these events in your Google Analytics dashboard.
