I can help you add Google AdSense to your Next.js 15 application. Next.js provides a convenient way to integrate third-party scripts like Google AdSense using the @next/third-parties library 1. Here's a step-by-step guide to add Google AdSense to your Next.js 15 application:

1. First, install the @next/third-parties library if you haven't already:

2. Create a new component for Google AdSense. Let's call it GoogleAdSense.tsx:

Make sure to replace "YOUR_AD_CLIENT_ID" with your actual Google AdSense client ID, and "YOUR_AD_SLOT_ID" with the specific ad slot ID you want to use.

A few important notes:

1. The GoogleAdSense component from @next/third-parties/google ensures that the AdSense script is loaded efficiently and in compliance with Next.js best practices 1.
2. The custom GoogleAdSense component we created uses the useEffect hook to push the ad after the component mounts. This is necessary because AdSense requires client-side JavaScript to function.
3. Remember to follow Google AdSense policies and guidelines when implementing ads on your site.
4. Test your implementation thoroughly in development and production environments to ensure ads are displaying correctly and not affecting your site's performance.

By following these steps, you should be able to successfully integrate Google AdSense into your Next.js 15 application. If you encounter any issues or need further customization, feel free to ask!

It seems that the GoogleAdSense export is not available in the @next/third-parties/google module as expected. Let's revise the code to address this error. We'll use a different approach to add Google AdSense to your Next.js 15 application.

In this revised version:

1. We've removed the reference to @next/third-parties/google as it doesn't provide the GoogleAdSense export we expected.
2. Instead, we're using Next.js's built-in Script component to load the AdSense script 1. This component is designed to optimize the loading of third-party scripts in Next.js applications.
3. The GoogleAdSense component now includes both the script loading and the ad placement code.
4. We've set the strategy prop of the Script component to "afterInteractive". This ensures that the script loads after the page becomes interactive, which is generally a good practice for ad scripts 1.
5. The RootLayout component in app/layout.tsx no longer needs to include any AdSense-specific code.
6. You can now use the GoogleAdSense component in any page where you want to display ads, as shown in the app/page.tsx example.

Remember to replace "YOUR_AD_CLIENT_ID" with your actual Google AdSense client ID, and "YOUR_AD_SLOT_ID" with the specific ad slot ID you want to use.

This approach should resolve the error you encountered and successfully integrate Google AdSense into your Next.js 15 application. If you have any more questions or encounter any issues, please don't hesitate to ask!
