SEO for Next.js Apps: What Actually Matters

Most Next.js SEO problems come from the fundamentals, not exotic edge cases. Use the Metadata API to give every page a unique title and description — not a duplicated default. Add a real `robots.ts` and `sitemap.ts` so crawlers can find every page instead of relying on internal links alone. Use semantic HTML (one H1, a real heading hierarchy after it) so both search engines and screen readers understand the page structure. And add structured data — Organization, Article, FAQPage where it genuinely applies — so search results can show more than a blue link. None of this replaces content people actually want to read, but skipping it means good content underperforms anyway.
