How long does it take Google to index a Next.js site?

After submitting your sitemap in Google Search Console, most pages are indexed within 3–14 days. New pages are usually picked up within 24–72 hours.

Do I still need llms.txt if I have robots.txt?

Yes. robots.txt controls traditional crawlers; llms.txt is a new standard specifically for large language model crawlers and AI search engines.

The 2026 SEO Checklist for Next.js Websites

Next.js 14 ships with first-class SEO primitives — the Metadata API, the App Router sitemap and robots files, streaming SSR, and built-in image optimization. Here is the exact checklist we run before every launch in 2026.

Why Next.js is built for SEO

Next.js renders HTML on the server by default, which means crawlers see fully populated markup instead of an empty <div id="root">. Combined with the new Metadata API, App Router file-based sitemap, and built-in image optimization, you can ship a technically perfect SEO foundation in a single afternoon.

The 14-point checklist

Set metadataBase in app/layout.tsx
Add a unique <title> and meta description per route
Define canonical URLs with alternates.canonical
Generate app/sitemap.ts with every dynamic route
Generate app/robots.ts pointing to your sitemap
Add Organization + WebSite JSON-LD site-wide
Add Service / Article / FAQPage JSON-LD per page type
Use next/image for every above-the-fold image
Hit LCP < 2.5s, INP < 200ms, CLS < 0.1
Add Open Graph + Twitter Card metadata
Add hreflang if you serve multiple locales
Add llms.txt for AI crawlers (ChatGPT, Perplexity, Claude)
Submit your sitemap to Google Search Console
Set up Google Analytics 4 + Search Console + Bing Webmaster

1. Set metadataBase once

Setting metadataBase in your root layout gives every page a canonical absolute URL for Open Graph and canonical tags. Without it, Next.js will warn you at build time and your social previews will break.

export const metadata = {
  metadataBase: new URL('https://yourdomain.com'),
}

2. Generate the sitemap from data, not by hand

Hand-maintained sitemaps go stale fast. Loop over your central content sources (services, blog posts, projects) inside app/sitemap.ts so every new route is indexed automatically.

3. Add schema markup per page type

Google rewards rich results. We add Organization + WebSite globally, Service on service pages, BreadcrumbList on nested pages, BlogPosting on blog posts, and FAQPage anywhere we list FAQs.

4. Do not skip llms.txt

llms.txt is the new robots.txt for AI search. ChatGPT, Perplexity, and Claude crawl it to understand your site's structure and which pages are canonical. Add one at /llms.txt today.
