## What it does

The skill supports two workflows: an SEO reference and a codebase audit. Its 31 rules are grouped into 8 areas, including Core Web Vitals, technical and on-page SEO, structured data, performance, social tags, React/SPA checks, and mobile-first requirements.

It identifies the project stack from `package.json` and the project structure before applying checks. Laravel Blade projects use server-rendered page rules, while Laravel with Inertia.js and React also gets SSR, `<Head>`, and `head-key` checks. The audit covers titles, descriptions, canonical links, `robots.txt`, XML sitemaps, headings, image `alt` text, JSON-LD, Open Graph, Twitter Cards, and loading behavior.

SPA checks are skipped for Laravel Blade because those pages are already server-rendered. That distinction affects which findings appear in an audit.

```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/AsyrafHussin/agent-skills/tree/HEAD/skills/seo-best-practices/SKILL.md

## When to use it
- audit pages and layout files for SEO issues
- check titles, descriptions, canonicals, and `robots.txt`
- inspect JSON-LD and social sharing metadata
- review Core Web Vitals and image loading
- set up SEO checks for Laravel with Inertia.js and React

## Example prompts
- Audit the SEO of the whole project.
- Check SEO only in `resources/views/home.blade.php`.
- Review metadata, JSON-LD, and Open Graph on the React pages.

# SEO Best Practices

Comprehensive SEO patterns for web applications built with React and Laravel. Contains 31 rules across 8 categories covering Core Web Vitals, technical SEO, structured data, performance, social sharing, and mobile-first indexing. Supports both **coding reference** and **audit mode**.

## Metadata

- **Version:** 1.2.0
- **Scope:** Laravel Blade and Laravel + Inertia.js + React
- **Rule Count:** 31 rules across 8 categories
- **License:** MIT

## How to Audit

When the user asks to "audit SEO", "check SEO", or "review SEO" — run the checklist below against their codebase.

### Audit Step 1: Determine Scope

- If arguments provided (`$ARGUMENTS`): audit only those pages or files
- If no arguments: audit all pages and layouts in the codebase

### Audit Step 2: Detect Project Type

Use the detection logic in "Step 1: Detect Project Type" below to determine Laravel Blade vs Laravel + Inertia + React.

### Audit Step 3: Run SEO Checklist

Work through every item below. For each, output:
- **PASS** — brief confirmation of what was verified
- **FAIL** — exact `file:line`, description of the issue, and fix recommendation
- **N/A** — if the check does not apply to this project

#### Core Web Vitals
- [ ] Hero/above-the-fold images use `fetchpriority="high"` and are preloaded (LCP < 2.5s)
- [ ] No long-running JavaScript tasks blocking interaction (INP < 200ms)
- [ ] All images and embeds have explicit `width`/`height` attributes (CLS < 0.1)
- [ ] No dynamically injected content that shifts layout without reserved space

#### Technical SEO
- [ ] Every page has a unique `<title>` tag (50-60 characters)
- [ ] Every page has a `<meta name="description">` (150-160 characters)
- [ ] Every page has a `<link rel="canonical">` pointing to the correct URL
- [ ] `robots.txt` exists and does not block important pages
- [ ] XML sitemap exists and includes all indexable pages
- [ ] URLs are clean, lowercase, hyphenated — no query params for indexable pages

#### On-Page SEO
- [ ] One `<h1>` per page containing the primary keyword
- [ ] Heading hierarchy is sequential (h1 → h2 → h3) — no skipped levels
- [ ] Images have descriptive `alt` text (not empty, not "image", not filename)
- [ ] Internal links use descriptive anchor text (not "click here")
- [ ] Semantic HTML used (`<article>`, `<section>`, `<nav>`, `<main>`)

#### Structured Data
```
