SKILL.md

This skill should be used when the user asks to "improve SEO", "add sitemap.xml", "fix meta tags", "add structured data", "set canonical URLs", "improve Core Web Vitals", "audit SEO", "programmatic SEO", or "build SEO pages at scale" in a Next.js App Router app. Perform no visual redesigns.

Overview

# Optimise SEO

Practical SEO improvements for Next.js App Router without visual redesign.

Constraints

No visual redesigns or layout changes. Allowed: metadata, structured data, semantic HTML, internal links, alt text, sitemap/robots, performance tuning.

Quick workflow

1) Inventory routes and index intent

2) Fix crawl/index foundations

3) Implement metadata + structured data

4) Improve semantics, links, and CWV

5) Validate and document

Must-have

Sitemap (app/sitemap.ts) and robots (app/robots.ts)
Canonicals consistent on every page
Unique titles + descriptions
OpenGraph + Twitter Card tags
JSON-LD: Organization, WebSite, BreadcrumbList (+ Article/Product/FAQ as needed)
One h1 and logical headings; semantic HTML
Alt text, internal links, CWV targets, mobile/desktop parity

Programmatic SEO (pages at scale)

Validate demand for a repeatable pattern before generating pages
Require unique value per page and defensible data
Use clean subfolder URLs, hubs/spokes, and breadcrumbs
Index only strong pages; monitor indexation and cannibalization

SEO audit (triage order)

1) Crawl/index: robots, sitemap, noindex, canonicals, redirects, soft 404s

2) Technical: HTTPS, CWV, mobile parity

3) On-page/content: titles/H1, internal links, remove or noindex thin pages

Outputs

List files changed and why
Provide validation results and remaining issues

Resources

nextjs-implementation.md for code examples
seo-checklist.md for launch checklist

Don't

Duplicate or missing titles/descriptions
Block crawlers unintentionally
Omit or conflict canonicals
Rely on JS-only rendering without SSR/SSG
Use generic or missing alt text
Use headings for styling
Over-generate thin pages or doorway pages
Keyword stuff or create cannibalization
Perform visual redesigns or layout changes

Validation

```bash

lighthouse https://site.com --output=json --output-path=report.json

cat report.json | jq '.categories.seo.score * 100' # Target: 90+

```
