Go Back to Your Code editor create a new folder named lib

Now,
create a new file named as gtag.js

and paste the following code over in gtag.js

Copy this Code

// https://developers.google.com/analytics/devguides/collection/gtagjs/pages
export const pageview = (url) => {
  window.gtag('config', GA_TRACKING_ID, {
    page_path: url,
  })

Note: This Tracking ID is just for testing purpose You will find your Tracking Id on the same page

Copy Your Tracking ID and paste it

Now go to pages folder in the github docs
Image description
Copy all this code to_app.js

import { useEffect } from 'react'
import Script from 'next/script'
import { useRouter } from 'next/router'
import * as gtag from '../lib/gtag'

const App = ({ Component, pageProps }) => {
  const router = useRouter()
  useEffect(() => {
    const handleRouteChange = (url) => {
      gtag.pageview(url)
    }
    router.events.on('routeChangeComplete', handleRouteChange)
    return () => {
      router.events.off('routeChangeComplete', handleRouteChange)
    }
  }, [router.events])

  return (
    <>
      {/* Global Site Tag (gtag.js) - Google Analytics */}
      <Script
        strategy="afterInteractive"
        src={`https://www.googletagmanager.com/gtag/js?id=${gtag.GA_TRACKING_ID}`}
      />
      <Script
        id="gtag-init"
        strategy="afterInteractive"
        dangerouslySetInnerHTML={{
          __html: `
            window.dataLayer = window.dataLayer || [];
            function gtag(){dataLayer.push(arguments);}
            gtag('js', new Date());
            gtag('config', '${gtag.GA_TRACKING_ID}', {
              page_path: window.location.pathname,
            });
          `,
        }}
      />
      <Component {...pageProps} />
    </>
  )
}

export default App
Enter fullscreen mode Exit fullscreen mode

Last Step is to go to _document.js file where actual tracking will take place
If you don't find _document.js file. Then just go to pages folder and create a new file named as _document.js.
And add the following code over in the file.
This is for google analytics.

 <script async src={`https://www.googletagmanager.com/gtag/js?id=${process.env.GA_TRACKING_ID}`}></script>
<script
                dangerouslySetInnerHTML={{
                  __html: `
                window.dataLayer = window.dataLayer || [];
                function gtag(){dataLayer.push(arguments);}
                gtag('js', new Date());
                gtag('config', '${process.env.GA_TRACKING_ID}', {
                  page_path: window.location.pathname,
                });
              `,
                }}
            />

Enter fullscreen mode Exit fullscreen mode

To add google adsense we just have to add 1 line.
for that follow the same steps create an account in google adsense
and get the script like this

 <script data-ad-client="ca-pub-xxxxx(yourid)" async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"/>
Enter fullscreen mode Exit fullscreen mode

Final code will be in _document.js file You can refer the main docs of NEXTJs Custom Doc

<Head>
 <script data-ad-client="ca-pub-xxxxx(yourid)" async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"/>
//##############
<script async src={`https://www.googletagmanager.com/gtag/js?id=${process.env.GA_TRACKING_ID}`}></script>
<script
                dangerouslySetInnerHTML={{
                  __html: `
                window.dataLayer = window.dataLayer || [];
                function gtag(){dataLayer.push(arguments);}
                gtag('js', new Date());
                gtag('config', '${process.env.GA_TRACKING_ID}', {
                  page_path: window.location.pathname,
                });
              `,
                }}
            />
</Head>
Enter fullscreen mode Exit fullscreen mode

Remember the whole code should be inside <Head></Head> Tag

Hope this might help you.

Okay so may be if you make separate component for ads and call it or import it on all the pages u want then it might work and i guess instead of keeping .jsx keep that adsence.jsx as adsence.js
