1. Introduction

Search Engine Optimization (SEO) is critical for enhancing the visibility of your Next.js applications. This lesson covers advanced SEO techniques tailored for Next.js, focusing on optimizing metadata, improving performance, and implementing structured data.

2. Key SEO Concepts

• On-page SEO: Optimizing content and HTML source code.
• Off-page SEO: External factors like backlinks and social media.
• Technical SEO: Improving site infrastructure for search engines.

3. SEO in Next.js

3.1 Dynamic Metadata

Next.js allows for dynamic metadata through the next/head component. You can customize the title and meta description based on route parameters.

import Head from 'next/head';

const Page = ({ title }) => (
    <>
        
            
            
        
        
{title}
    
);
                

3.2 Server-side Rendering (SSR)

Utilizing SSR enhances SEO by serving fully-rendered pages to search engines. Use getServerSideProps for fetching data on each request.

export async function getServerSideProps() {
    const data = await fetch('https://api.example.com/data');
    const json = await data.json();
    return { props: { json } };
}
                

3.3 Sitemap Generation

A sitemap helps search engines crawl your site effectively. You can generate a sitemap using packages like next-sitemap.

module.exports = {
    siteUrl: 'https://example.com',
    generateRobotsTxt: true,
}
                

3.4 Structured Data

Structured data helps search engines understand your content better. Use JSON-LD format within the next/head component.

const structuredData = {
    "@context": "https://schema.org",
    "@type": "WebSite",
    "name": "My Website",
    "url": "https://example.com"
};

const Page = () => (
    
        
    
);
