Why is SEO important for Next.js apps?

Next.js supports server-side rendering (SSR). How does SSR help with SEO?

ASSR hides content from search engines to protect privacy.
BSSR makes the app load slower, which helps SEO by giving time to bots.
CSSR disables JavaScript, so search engines only see plain text.
DSSR allows search engines to see fully rendered HTML, improving indexing.

What is the SEO effect of client-side data fetching in Next.js?

Consider a Next.js page that fetches data only on the client side using useEffect. What SEO impact does this have?

NextJS
import { useState, useEffect } from 'react';

export default function Page() {
  const [data, setData] = useState(null);
  useEffect(() => {
    fetch('/api/data').then(res => res.json()).then(setData);
  }, []);

  return <div>{data ? data.message : 'Loading...'}</div>;
}
ASearch engines see full data immediately, improving SEO.
BSearch engines ignore client-side data fetching and index the page fully.
CSearch engines see only 'Loading...' because data loads after page render, hurting SEO.
DClient-side fetching causes a syntax error, so SEO is not affected.

💡 Hint

Think about when the data appears in the HTML sent to the browser.

Why does this Next.js page have poor SEO despite using SSR?

Review this Next.js page code. It uses getServerSideProps but search engines report missing content. What is the likely cause?

NextJS
export async function getServerSideProps() {
  return { props: {} };
}

export default function Page({ data }) {
  return <div>{data.message}</div>;
}
AThe component should use <code>useEffect</code> to fetch data for SEO.
BThe <code>data</code> prop is undefined because <code>getServerSideProps</code> returns empty props, so no content renders.
CNext.js does not support <code>getServerSideProps</code> for SEO.
DThe page has a syntax error in <code>getServerSideProps</code> causing SSR to fail.

💡 Hint

Check what props are passed and used in the component.
