Technical SEO for Next.js Websites: A Complete Guide
Getting your Next.js website to rank on Google requires more than great content—you need solid technical SEO. This comprehensive guide covers everything from meta tags to Core Web Vitals optimization.
Why Next.js is Perfect for SEO
Next.js offers several SEO advantages:
- Server-Side Rendering (SSR): Search engines see fully rendered content
- Static Site Generation (SSG): Lightning-fast page loads
- Automatic code splitting: Optimized page weight
- Built-in image optimization: Faster loading times
- API routes: Dynamic sitemap and robots.txt generation
1. Meta Tags and Social Sharing
Dynamic SEO Component
Create a reusable SEO component for all pages:
// components/PageSEO.tsx
import Head from "next/head";
import { useRouter } from "next/router";
interface SEOProps {
title: string;
description: string;
keywords?: string;
ogImage?: string;
canonicalUrl?: string;
}
export default function PageSEO({
title,
description,
keywords,
ogImage = "/og-default.jpg",
canonicalUrl,
}: SEOProps) {
const router = useRouter();
const baseUrl = "https://starworks.in";
const fullUrl = canonicalUrl || `${baseUrl}${router.asPath}`;
return (
<Head>
<title>{title} | Star Works</title>
<meta name="description" content={description} />
{keywords && <meta name="keywords" content={keywords} />}
{/* Canonical URL */}
<link rel="canonical" href={fullUrl} />
{/* Open Graph */}
<meta property="og:title" content={title} />
<meta property="og:description" content={description} />
<meta property="og:image" content={`${baseUrl}${ogImage}`} />
<meta property="og:url" content={fullUrl} />
<meta property="og:type" content="website" />
{/* Twitter Card */}
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:title" content={title} />
<meta name="twitter:description" content={description} />
<meta name="twitter:image" content={`${baseUrl}${ogImage}`} />
</Head>
);
}
Usage Example:
// pages/services.tsx
export default function Services() {
return (
<>
<PageSEO
title="Web Development Services"
description="Professional web development services including Next.js, React, and custom solutions for businesses."
keywords="web development, Next.js development, React development"
ogImage="/images/services-og.jpg"
/>
<ServicesContent />
</>
);
}
2. Structured Data (Schema Markup)
Organization Schema
// components/StructuredData.tsx
export default function OrganizationSchema() {
const schema = {
"@context": "https://schema.org",
"@type": "Organization",
name: "Star Works",
url: "https://starworks.in",
logo: "https://starworks.in/logo.png",
description: "Professional web development and digital solutions",
address: {
"@type": "PostalAddress",
addressCountry: "IN",
addressRegion: "Haryana",
},
sameAs: [
"https://github.com/star-works",
"https://linkedin.com/company/star-works",
],
};
return (
<script
type="application/ld+json"
dangerouslySetInnerHTML={{ __html: JSON.stringify(schema) }}
/>
);
}
Article Schema for Blog Posts
export function ArticleSchema({ post }) {
const schema = {
"@context": "https://schema.org",
"@type": "BlogPosting",
headline: post.title,
description: post.excerpt,
image: post.coverImage,
datePublished: post.publishedAt,
author: {
"@type": "Person",
name: post.author.name,
},
publisher: {
"@type": "Organization",
name: "Star Works",
logo: {
"@type": "ImageObject",
url: "https://starworks.in/logo.png",
},
},
};
return (
<script
type="application/ld+json"
dangerouslySetInnerHTML={{ __html: JSON.stringify(schema) }}
/>
);
}
3. Dynamic Sitemap Generation
Create API Route for Sitemap
// pages/api/sitemap.xml.ts
import { NextApiRequest, NextApiResponse } from "next";
export default async function handler(
req: NextApiRequest,
res: NextApiResponse
) {
const baseUrl = "https://starworks.in";
// Static pages
const staticPages = ["", "/about", "/services", "/contact", "/blog"];
// Fetch dynamic blog posts
const blogPosts = await getBlogPosts(); // Your function
const sitemap = `<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
${staticPages
.map(
(page) => `
<url>
<loc>${baseUrl}${page}</loc>
<lastmod>${new Date().toISOString()}</lastmod>
<changefreq>weekly</changefreq>
<priority>0.8</priority>
</url>
`
)
.join("")}
${blogPosts
.map(
(post) => `
<url>
<loc>${baseUrl}/blog/${post.slug}</loc>
<lastmod>${post.publishedAt}</lastmod>
<changefreq>monthly</changefreq>
<priority>0.6</priority>
</url>
`
)
.join("")}
</urlset>
`;
res.setHeader("Content-Type", "text/xml");
res.write(sitemap);
res.end();
}
4. Robots.txt Configuration
// pages/api/robots.txt.ts
import { NextApiRequest, NextApiResponse } from "next";
export default function handler(req: NextApiRequest, res: NextApiResponse) {
const robots = `
User-agent: *
Allow: /
Disallow: /api/
Disallow: /admin/
Sitemap: https://starworks.in/api/sitemap.xml
`.trim();
res.setHeader("Content-Type", "text/plain");
res.send(robots);
}
5. Core Web Vitals Optimization
Image Optimization
import Image from "next/image";
export default function OptimizedImage() {
return (
<Image
src="/hero.jpg"
alt="Hero banner"
width={1200}
height={600}
priority // For above-the-fold images
quality={85}
placeholder="blur"
blurDataURL="data:image/jpeg;base64,..."
/>
);
}
Font Loading Strategy
// app/layout.tsx
import { Inter, Kanit } from "next/font/google";
const inter = Inter({
subsets: ["latin"],
display: "swap",
variable: "--font-inter",
});
const kanit = Kanit({
weight: ["400", "700"],
subsets: ["latin"],
display: "swap",
variable: "--font-kanit",
});
export default function RootLayout({ children }) {
return (
<html lang="en" className={`${inter.variable} ${kanit.variable}`}>
<body>{children}</body>
</html>
);
}
6. Internal Linking Strategy
Breadcrumbs Implementation
// components/Breadcrumbs.tsx
import Link from "next/link";
interface Breadcrumb {
label: string;
href: string;
}
export default function Breadcrumbs({ items }: { items: Breadcrumb[] }) {
const schema = {
"@context": "https://schema.org",
"@type": "BreadcrumbList",
itemListElement: items.map((item, index) => ({
"@type": "ListItem",
position: index + 1,
name: item.label,
item: `https://starworks.in${item.href}`,
})),
};
return (
<>
<nav className="breadcrumbs">
{items.map((item, index) => (
<span key={index}>
{index > 0 && " / "}
<Link href={item.href}>{item.label}</Link>
</span>
))}
</nav>
<script
type="application/ld+json"
dangerouslySetInnerHTML={{ __html: JSON.stringify(schema) }}
/>
</>
);
}
7. Mobile Optimization
Responsive Meta Tags
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=5" />
<meta name="mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-capable" content="yes" />
8. Analytics and Monitoring
Google Analytics 4 Integration
// components/Analytics.tsx
import Script from "next/script";
export default function Analytics() {
return (
<>
<Script
src={`https://www.googletagmanager.com/gtag/js?id=G-XXXXXXXXXX`}
strategy="afterInteractive"
/>
<Script id="google-analytics" strategy="afterInteractive">
{`
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', 'G-XXXXXXXXXX');
`}
</Script>
</>
);
}
9. Performance Monitoring
Track Core Web Vitals
// pages/_app.tsx
export function reportWebVitals(metric) {
if (metric.label === "web-vital") {
console.log(metric); // Send to analytics
}
}
