Check out new NextJs Third-Parties Component

After watching the NextJS Conf2023, they released @next/third-parties because of people reporting in the past months after they followed the Google Analytics Documentation, it made bad perfomance issues on Lighhouse.

After following NextJs documentation guide, I was able to fully setup Google Analytics on NextJs 14.

1. To load Google Tag Manager for all routes, include the component directly in your root layout:

app/layout.tsx

import { GoogleTagManager } from '@next/third-parties/google'

export default function RootLayout({children}: {children: React.ReactNode}) {
    return (
        <html lang="en">
            <body>{children}</body>
            <GoogleTagManager gtmId="GTM-XYZ" />
        </html>
     )
}

2. To load Google Tag Manager for a single route, include the component in your page file:

app/page.js

import { GoogleTagManager } from '@next/third-parties/google'

export default function Page() {
    return <GoogleTagManager gtmId="GTM-XYZ" />
}

Note: This is the Official NextJs Documentation.

Set up the Google tag with gtag.js | Tag Platform | Google for Developers

To use the Google tag, copy your tag ID from a Google product (e.g., Google Ads, Analytics), paste it into the provided code snippet, and place the snippet on every page you want to track. Verify your Google tag implementation using Tag Assistant to ensure it's sending data correctly by checking for your tag ID and consulting the Tag Manager help center for troubleshooting.

Anyone Explain Google Tag Manager to me Please in Simple

Imagine your website is a physical store. Google Tag Manager (GTM) is like an advanced "camera system" that observes visitors when they enter your store and notifies your "partners" (such as Google Analytics, Google Ads, or Meta) about what those visitors do. For example, GTM can simply notify when a visitor arrives or provide more detailed insights, like tracking the areas they visit, the products they view, the items in their cart, or whether they complete a purchase or submit a form. However, it’s important to note that GTM itself does not analyze the data. Instead, it enables the tools you connect to it—like Google Analytics or Facebook Ads Manager—to perform the analysis and give you insights. Think of GTM as the messenger, not the decision-maker. The great part? Instead of installing a separate system for each of your partners, you install one GTM system and configure it to notify all your tools as needed. How GTM Works: Tags: Tags are the connections between GTM and your partners. Each tag sends specific information (like clicks, purchases, or video plays) to tools like Google Analytics or Meta Ads. Triggers: Triggers are the actions you want to monitor, such as a visitor clicking a button, submitting a form, or scrolling down a page. Variables: Variables are like reusable templates or placeholders for information. For example, you can store your Google Analytics ID in a variable and reference it across multiple tags. If the ID changes, you only need to update the variable once, and all related tags will update automatically. To set it up, you install a JavaScript tag on your website. Then, by configuring triggers, tags, and variables, you can track visitor behavior and share that data with the tools you use to analyze it. More on reddit.com

Google Tag Manager / Google Analytics - No Code?

Yes, you can utilise those native DOM events assuming:

You can readily identify the elements in question in the page DOM. ie: are there ID attributes on the buttons you want to track?
You only want to track these 'simple' events, and not 'custom' events.
You do not need to expose any backend data to GTM/GA.

At that level of complexity GTM can more or less be a point and click kind of set-up.
