❌ Example of incorrect code

import Head from 'next/head';

export default function Page() {
    return (
        <>
            <Head>
                <title>
                    My page title
                </title>
            </Head>
        </>
    );
}

✅ Example of correct code

export default function Head() {
    return (
        <>
            <title>
                My page title
            </title>
        </>
    );
