SEO for Next.js: Metadata API Complete Guide

Introduction to the Metadata API

The Metadata API is a powerful tool in Next.js that allows you to manage and optimize your application's metadata. With the Metadata API, you can set and update metadata properties, such as title, description, and keywords, for each page in your application.

Setting Metadata Properties

To set metadata properties using the Metadata API, you need to import the useMetadata hook and pass an object with the desired metadata properties. For example:

import { useMetadata } from 'next/head';

function HomePage() {
  useMetadata({
    title: 'Home Page',
    description: 'This is the home page of our application',
    keywords: ['home', 'page', 'application'],
  });

  return <div>Welcome to our application!</div>;
}

Updating Metadata Properties

To update metadata properties dynamically, you can use the useMetadataUpdate hook. For example:

import { useMetadata, useMetadataUpdate } from 'next/head';

function HomePage() {
  const updateMetadata = useMetadataUpdate();

  const handleUpdateMetadata = () => {
    updateMetadata({
      title: 'Updated Home Page',
      description: 'This is the updated home page of our application',
      keywords: ['updated', 'home', 'page'],
    });
  };

  return (
    <div>
      <button onClick={handleUpdateMetadata}>Update Metadata</button>
      <div>Welcome to our application!</div>
    </div>
  );
}
