# 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
- Present required tags
### 3. Prioritize and Fix Issues
Address issues in priority order:
#### Priority 1: Critical Issues
**Missing or Poor Title Tags**:
```html
<!-- Add unique, descriptive title to <head> -->
<title>Primary Keyword - Secondary Keyword | Brand Name</title>
```
- Keep 50-60 characters
- Include target keywords at the beginning
- Make unique for each page
**Missing Meta Descriptions**:
```html
<!-- Add compelling description to <head> -->
<meta name="description" content="Clear, concise description that includes target keywords and encourages clicks. 150-160 characters.">
```
**Missing H1 or Multiple H1s**:
- Ensure exactly ONE H1 per page
- H1 should describe the main topic
- Should match or relate to title tag
**Images Without Alt Text**:
```html
<!-- Add descriptive alt text to all images -->
<img src="image.jpg" alt="Descriptive text explaining image content">
```
**Missing HTML Lang Attribute**:
```html
<!-- Add to opening <html> tag -->
<html lang="en">
```
#### Priority 2: Important Optimizations
**Viewport Meta Tag** (critical for mobile SEO):
```html
<meta name="viewport" content="width=device-width, initial-scale=1.0">
```
**Charset Declaration**:
```html
<meta charset="UTF-8">
```
**Open Graph Tags** (for social media sharing):
```html
<meta property="og:title" content="Your Page Title">
<meta property="og:description" content="Your page description">
<meta property="og:image" content="https://example.com/image.jpg">
<meta property="og:url" content="https://example.com/page-url">
<meta property="og:type" content="website">
```
**Twitter Card Tags**:
```html
<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:title" content="Your Page Title">
<meta name="twitter:description" content="Your page description">
<meta name="twitter:image" content="https://example.com/image.jpg">
```
**Canonical URL**:
```html
<link rel="canonical" href="https://example.com/preferred-url">
```
#### Priority 3: Advanced Optimization
**Schema Markup** - Refer to `references/schema_markup_guide.md` for detailed implementation. Common types:
- Organization (homepage)
- Article/BlogPosting (blog posts)
- LocalBusiness (local businesses)
- Breadcrumb (navigation)
- FAQ (FAQ pages)
- Product (e-commerce)
Example implementation:
```html
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "Article",
"headline": "Article Title",
"author": {
"@type": "Person",
"name": "Author Name"
},
"datePublished": "2024-01-15",
"image": "https://example.com/image.jpg"
}
</script>
```
### 4. Generate or Update Sitemap
After fixing issues, generate an XML sitemap:
```bash
python scripts/generate_sitemap.py <directory> <base_url> [output_file]
```
**Example**:
```bash
# Generate sitemap for website
python scripts/generate_sitemap.py ./public https://example.com
# Specify output location
python scripts/generate_sitemap.py ./public https://example.com ./public/sitemap.xml
```
The script:
- Automatically finds all HTML files
- Generates proper URLs
- Includes lastmod dates
- Estimates priority and changefreq values
- Creates properly formatted XML sitemap
**After generation**:
1. Upload sitemap.xml to website root
2. Add reference to robots.txt
3. Submit to Google Search Console and Bing Webmaster Tools
### 5. Update robots.txt
Use the template from `assets/robots.txt` and customize:
```
User-agent: *
Allow: /
# Block sensitive directories
Disallow: /admin/
Disallow: /private/
# Reference your sitemap
Sitemap: https://yourdomain.com/sitemap.xml
```
Place robots.txt in website root directory.
