About this product
A 120-point technical SEO audit built for Next.js App Router sites (Next.js 15 & 16). Every check tells you what to look for, how to verify it in minutes, and the exact Next.js fix: metadata, robots.ts, sitemap.ts, canonicals, redirects, rendering, Core Web Vitals, JSON-LD and hreflang.
Generic SEO checklists say "add a canonical tag". This one says where it goes in generateMetadata, why a canonical in your root layout can point every page at your home page, and how to confirm the fix in Search Console.
What's inside
25-page PDF guide: a 15-minute triage for the 12 most common Next.js SEO bugs, 120 checks in 14 areas (each with how-to-verify, Next.js fix and a Critical/High/Medium/Low priority), Core Web Vitals targets, a launch and migration runbook, and a reporting guide.
Audit tracker (XLSX, works in Excel and Google Sheets): all 120 checks with status dropdowns, a priority-weighted score per area, an overall score, an open-Critical counter and a readiness verdict. Also a Core Web Vitals grader, URL inventory, redirect map and issue log.
Client audit report template (DOCX): executive summary, top priorities, scorecard, finding blocks with a filled example, CWV table and fix plan.
10 copy-paste snippets: root layout metadata, generateMetadata with notFound, environment-aware robots.ts, sitemap.ts, permanent redirects, JSON-LD, hreflang alternates, an X-Robots-Tag header in proxy.ts, an LCP image and a curl check.
Plain-text version (TXT) of every check and snippet for Notion, GitHub issues or AGENTS.md.
Quick-Start PDF to run your first audit in one afternoon.
The 14 audit areas

Who it's for
Developers and freelancers who build Next.js sites for clients and want to hand over an SEO-ready launch.
Agencies and SEOs who audit Next.js sites and need fixes the dev team can apply straight away.
Founders running a Next.js marketing site, blog or SaaS who aren't sure why pages aren't indexed.
What you'll be able to do
Catch launch-killers fast: a staging Disallow: / or noindex on production, layout-inherited canonicals, soft 404s, content that only appears after client-side fetches.
Score a site out of 100% by area and know exactly what to fix first.
Ship a clean migration with a tested 308/301 redirect map.
Send clients a professional audit report instead of a screenshot of Lighthouse.
Checked against official docs
Next.js and Google guidance was checked against nextjs.org/docs, developers.google.com/search and web.dev on 23 October 2026, including the Next.js 16 changes (proxy.ts replacing middleware.ts, image preload replacing priority). Sources are listed in the guide.
