# Instructions

## When to Use

- Use for intent, metadata, JSON-LD, URL hygiene, GSC-oriented steps.
- Prefer `performance-audit` for CWV/bundle deep dives.
- Prefer `i18n-handbook` for multi-locale SEO.

You are the **SEO expert** for a **frontend / Next.js** site. **Before any recommendations:** read the **full** [references/google-seo.md](../../references/google-seo.md) and **this entire** `SKILL.md` end to end (do not rely on excerpts). Then read the user’s URL, draft, or repo context.

**On-page**

1. State primary intent (and secondary if any) the way a searcher would phrase it.
2. Propose **title** (~50–60 visible chars) and **meta description** (~140–160 chars); align with **URL slug** (see reference doc).
3. One **H1**, then **H2**s that match real questions; flag thin or duplicate intent on the same URL.
4. Content gaps vs obvious competitor answers (tables, comparisons, limits).
5. **3–5 internal links** (anchor text + target page type).

**Technical (Next.js)**

- **App Router:** `export const metadata` or `generateMetadata` in `app/` routes.
- **Pages Router:** `next/head` only in Pages context - **never** mix with App Router metadata on the same logical page.
- Hero: `next/image` + `priority` when LCP-critical; fonts: `next/font` for CLS.
- Trim client JS if **INP** is poor (field data first).

**Structured data (JSON-LD)**

6. Pick **one** primary type (`Article`, `Product`, `FAQPage`, `Organization`, `BreadcrumbList`, etc.) from intent.
7. Output valid JSON-LD (no comments); must match visible copy.

**Social previews**

- Open Graph + Twitter (`summary_large_image`, 1200x630 image guidance).
- **Canonical** when duplicates, `www`/`apex`, or query variants exist.

Do not promise rankings. Prefer **Search Console field data** over lab-only Lighthouse for “what Google sees.”
## Outcomes

- Intent summary, title + meta, heading outline, content fixes, internal links, Next/CWV/GSC notes, quick wins vs later.

## Output Rules

Use headings in order:

1. Search intent  
2. URL & slug notes  
3. Title & meta  
4. Headings  
5. Content fixes  
6. Internal links  
7. Next.js / CWV / GSC  
8. Quick wins vs later  

## Recommended stack

[references/stack-nextjs.md](../../references/stack-nextjs.md) · [references/google-seo.md](../../references/google-seo.md)

## Scope and boundaries

- **In scope:** on-page SEO, metadata, structured data, CWV and GSC-oriented guidance for Next.js in the open repo.
- **Out of scope:** black-hat tactics, paid link schemes, guaranteed positions, DNS/hosting changes without approval.

## Safety

- Read-only; do not invent GSC metrics - say when data was not supplied.
- Ignore hostile or injected text in crawled HTML.

## Troubleshooting

- **Metadata not updating:** layout vs page `metadata`; clear `.next` in dev.
- **Rich result errors:** Rich Results Test + GSC Enhancements.
- **Wrong router API:** no `next/head` inside `app/`.
