Optimise SEO

IS: crawlability, metadata, structured data, canonicals, redirects, status codes, hreflang, AI-crawler policy and extractable page structure, Core Web Vitals, programmatic SEO, security and privacy headers, and error-page behaviour, implemented in a Next.js App Router codebase.
IS NOT: visual redesign, layout, or page-level UI quality (ui-design Direction, Build, and Audit modes), demand research, briefs, question maps, or Search Console monitoring (seo-program), tenant routing for robots.txt and sitemap.xml (multi-tenant-architecture), or writing the article (external ghostwriter).

Allowed surface: metadata and generateMetadata, JSON-LD, semantic HTML, internal links, alt text, app/sitemap.ts, app/robots.ts, app/feed.xml/route.ts, app/llms.txt/route.ts, proxy.ts, next.config.ts redirects and headers, error pages, and performance work. Component styling and layout stay as they are; when a fix needs a layout change, name it as a handoff to ui-design.

Before writing code, read the matching guide in node_modules/next/dist/docs/ (resolved from the app directory; in a monorepo the next package is not visible from the repo root). The bundled docs match the installed version; the notes in references/nextjs-implementation.md were checked against 16.3 and say where behaviour changed.

Workflow

Copy and track this checklist:

SEO progress:
- [ ] Step 1: Inventory routes and decide index intent per route
- [ ] Step 2: Fix crawl/index foundations (sitemap, robots, canonicals, redirects, status codes)
- [ ] Step 3: Implement metadata and structured data
- [ ] Step 4: Improve semantics, extractable answers, internal links, and Core Web Vitals
- [ ] Step 5: Validate with references/seo-checklist.md and report evidence

Step 1 is a table: route, index or noindex, canonical, reason. Every later step reads from it, and a route with no row gets no work.

Must-have on every site

app/sitemap.ts lists every indexable URL with lastModified derived from content; app/robots.ts names it
One canonical per page, one host, one casing, one trailing-slash policy, set through alternates.canonical with metadataBase in the root layout. Next.js enforces the slash policy itself: by default it 308s /about/ to /about, and trailingSlash: true inverts that (files with extensions and .well-known/ paths are exempt either way)
Preserve the property's existing ownership verification. Use metadata.verification only for a supplied token and the chosen verification method; DNS verification needs no duplicate meta tag
Root layout robots lifts Google's default preview caps: googleBot: { 'max-snippet': -1, 'max-image-preview': 'large', 'max-video-preview': -1 }. Without them Google truncates the snippet and the image preview, and the snippet cap is what AI surfaces read against when deciding how much of a page they may quote
authors and creator set explicitly in the root layout, so person-level attribution does not live only in footer HTML and JSON-LD
Unique title and description per page; title and H1 lead with the non-brand primary keyword and agree in intent (a brand-led title on a category page competes only for navigational queries the site already wins)
Every page opens with a short, plain-text answer to the question it exists to answer; the h2s are the questions people actually ask
Open Graph and Twitter Card tags with a 1200x630 image
JSON-LD: Organization and WebSite once in a root @graph with stable @ids, BreadcrumbList on inner pages, then Article, Product, ProfilePage, or LocalBusiness where the content type matches. Define an entity once and reference it by @id
One h1, logical h2-h6, descriptive alt text, internal links between related pages
Core Web Vitals in target at the p75 of CrUX field data: LCP 2.5 s, INP 200 ms, CLS 0.1 (INP replaced FID in March 2024; a guide still naming FID is stale)

Redirects and indexing policy

Load references/indexing-policy.md when routes move, duplicates need consolidation, or page indexing policy changes. Verify behavior against the installed Next.js version and served responses.

AI crawlers and answer engines

Google needs no special files: AI Overviews and AI Mode run on Googlebot and core ranking, and nosnippet or max-snippet:0 is the only opt-out (it removes the normal snippet too). Everything else is a robots decision per crawler class: search and citation bots (OAI-SearchBot, Claude-SearchBot, PerplexityBot) put a site in answers; training bots (GPTBot, ClaudeBot, CCBot) do not; Google-Extended and Applebot-Extended are usage tokens with no crawler behind them. llms.txt costs one route and earns almost nothing measurable. The full table, robots.ts rules, Content-Signal, and the Markdown-alternate patterns are in references/answer-engines.md.

Programmatic SEO

For pages generated at scale, load references/indexing-policy.md. Require demand evidence and unique page value before indexing a new pattern.

Audit triage order

Crawl and index: robots, sitemap, stray noindex, canonicals, redirect chains, soft 404s
Technical: HTTPS, Core Web Vitals field data, mobile and desktop parity, AI-crawler access through the CDN
On-page: title and H1 uniqueness and non-brand lead, extractable answer, internal links, thin pages
Orphans: indexable pages with no internal link or sitemap entry; give them a crawl path or noindex and drop them. A sitewide footer link is not a crawl path on a low-authority domain: Google discounts footer boilerplate, and a section linked only from the footer can sit at "URL is unknown to Google" for months while nav-linked pages beside it are crawled daily

Report in the same order: what blocks indexation first, then on-page and schema gaps, then the single next fix. Twenty equal-weight findings get none of them done. Report length follows what was found, not the section list. Treat third-party audit tools as leads, not findings: several flag Next.js output falsely (a missing <meta name="title"> when <title> is present, "duplicate" theme-color tags that are light and dark variants, repeated article:tag), and at least one agent-skill auditor silently skips modules unless given an explicit module list and passes a FAQPage whose answers never render. Verify each lead against the served HTML before it goes in the report.

Gotchas

Under cacheComponents: true (the scaffold-nextjs default) the dynamic, dynamicParams, revalidate, and fetchCache segment configs are build errors: export const revalidate on app/sitemap.ts, dynamic = 'force-static' on a robots.txt/route.ts handler, fetchCache anywhere (runtime, maxDuration, instant, and prefetch remain valid). Move the content fetch into a separate 'use cache' helper with cacheLife('hours') and cacheTag, called from the page or GET (the directive cannot sit on the GET export itself), and revalidateTag(tag, 'max') from the publish webhook. Revalidation does not purge a CDN in front of the app; purge it in the same webhook.
generateSitemaps() writes /product/sitemap/0.xml, /product/sitemap/1.xml, and no index file. List each generated file in robots.ts (sitemap takes an array) or hand-write the index at app/sitemap.xml/route.ts; otherwise Google sees only the ones it stumbles on.
lastModified: new Date() on every sitemap row marks the whole site as changed on every deploy; Google then ignores lastmod sitewide. priority and changeFrequency are ignored outright, so emitting them buys nothing and clutters the diff.
No Host: line in robots.txt. Yandex dropped the directive in 2018 in favour of a 301 to the preferred host, which next.config.ts already serves, and auditors flag the leftover line as an unknown directive. Leave host out of the robots.ts return value.
Next.js replaces object-valued metadata (openGraph, twitter, robots, alternates) wholesale when a child segment declares the key; it does not deep-merge. A page that adds openGraph: { title } loses the inherited siteName, images, and locale, and images: undefined counts as a declaration. When you add one of these blocks to a route, every field the parent supplied becomes yours to restate. Scalars (title, description, authors, creator) merge normally.
title.template applies to <title> only. og:title resolves against openGraph.title.template, a separate mechanism, so stripping a hand-rolled suffix from a page title silently strips the product name from the share card. Set both templates in the layout, or neither. A bare string title in a nested layout also resets the parent template to null for that subtree; return { default, template } instead.
Never set openGraph.url in a root layout. It is not per-page, every route inherits it, and every share collapses onto the home URL. A child cannot fix it without declaring openGraph and losing the rest of the block. Absent beats wrong: consumers fall back to the URL they fetched, and alternates.canonical is already per-page.
middleware.ts is deprecated in Next.js 16. New request-time logic (slug checks, CSP nonces, Accept negotiation) goes in proxy.ts with an exported proxy function; npx @next/codemod@canary middleware-to-proxy . moves an existing file. Proxy is Node.js only; runtime is not a valid export there.
next.config.ts redirects match in array order and :path* swallows everything beneath it, so a specific source placed after a catch-all is dead code, and a bare /old must sit above /old/:path* or it lands on /new/. Vercel caps the list at 1,024 rules; past that, move the map into proxy.ts.
Next owns the Vary header on App Router HTML responses and replaces it with its RSC list (rsc, next-router-state-tree, ...). A Vary: Accept set in proxy.ts on NextResponse.next(), or in headers(), never reaches the client. It survives only on a Response you construct yourself, so content-negotiated Markdown must be returned directly, not rewritten to.
notFound() after a Suspense boundary or loading.tsx has flushed returns 200 with a noindex meta, not 404. Without Cache Components, call it before the first suspending await; with Cache Components the docs are explicit that every dynamic route streams a static shell first, so the existence check moves to proxy.ts. Analytics and uptime monitors otherwise see a health
