The skill scans HTML/CSS pages for SEO faults, then fixes meta tags, structured data and the sitemap. Handy when a site exists but search engines barely notice it.

## What it does

Two Python scripts and a schema.org reference sit inside. `scripts/seo_analyzer.py` walks a single file or a whole directory and checks titles, meta descriptions, the H1–H6 order, image alt text, Open Graph and Twitter Card tags, canonical links, lang and viewport. It prints a readable report, or JSON with `--json`, and sorts findings into critical, warnings and already-good.

\`scripts/generate_sitemap.py` takes a directory plus a base URL and turns every HTML file into an XML entry with lastmod and estimated priority and changefreq. The skill then walks you through placing `sitemap.xml` and linking it from `robots.txt`; a starter robots file is in `assets/robots.txt`.

It works on static markup. A PHP template, a page rendered at request time or an SPA with an empty `<body>` gives the analyzer nothing to read, since it only opens HTML files on disk. Both scripts run through `python`, so the interpreter must be on your machine before the first audit.

# SEO Optimizer

## Overview

This skill provides comprehensive SEO optimization capabilities for HTML/CSS websites. It analyzes websites for SEO issues, implements best practices, and generates optimization reports covering all critical SEO aspects including meta tags, heading structure, image optimization, schema markup, mobile optimization, and technical SEO.

## When to Use This Skill

Use this skill when the user requests:
- "Analyze my website for SEO issues"
- "Optimize this page for SEO"
- "Generate an SEO audit report"
- "Fix SEO problems on my website"
- "Add proper meta tags to my pages"
- "Implement schema markup"
- "Generate a sitemap"
- "Improve my site's search engine rankings"
- Any task related to search engine optimization for HTML/CSS websites

## Workflow

### 1. Initial SEO Analysis

Start with comprehensive analysis using the SEO analyzer script:

```bash
python scripts/seo_analyzer.py <directory_or_file>
```

This script analyzes HTML files and generates a detailed report covering:
- Title tags (length, presence, uniqueness)
- Meta descriptions (length, presence)
- Heading structure (H1-H6 hierarchy)
- Image alt attributes
- Open Graph tags
- Twitter Card tags
- Schema.org markup
- HTML lang attribute
- Viewport and charset meta tags
- Canonical URLs
- Content length

**Output Options**:
- Default: Human-readable text report with issues, warnings, and good practices
- `--json`: Machine-readable JSON format for programmatic processing

**Example Usage**:
```bash
# Analyze single file
python scripts/seo_analyzer.py index.html

# Analyze entire directory
python scripts/seo_analyzer.py ./public

# Get JSON output
python scripts/seo_analyzer.py ./public --json
```

### 2. Review Analysis Results

The analyzer categorizes findings into three levels:

**Critical Issues (🔴)** - Fix immediately:
- Missing title tags
- Missing meta descriptions
- Missing H1 headings
- Images without alt attributes
- Missing HTML lang attribute

**Warnings (⚠️)** - Fix soon for optimal SEO:
- Suboptimal title/description lengths
- Multiple H1 tags
- Missing Open Graph or Twitter Card tags
- Missing viewport meta tag
- Missing schema markup
- Heading hierarchy issues

**Good Practices (✅)** - Already optimized:
- Properly formatted elements
- Correct lengths
