Next.js SEO Checklist for Modern Agency Websites
A technical SEO checklist for Next.js agency websites covering metadata, schema, sitemaps, robots, Core Web Vitals, and internal links.
Use route-level metadata
Every important page should have a unique SEO title, meta description, canonical URL, Open Graph tags, Twitter card data, and crawl directives.
Templates help keep metadata consistent while avoiding duplicate titles across service and blog pages.
Add schema where it matches the page
Organization and Website schema belong globally. Service pages should include Service or ProfessionalService schema, breadcrumbs, and FAQ schema when FAQs are visible on the page.
Blog posts should include BlogPosting schema with author, publisher, image, and publish dates.
Protect Core Web Vitals
SEO gains disappear if the site feels slow. Optimize images, reduce blocking JavaScript, prefer static rendering, use font display swap, and avoid layout shifts.
A fast, crawlable site is easier for both search engines and customers to trust.
