- 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:
# 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:
<!-- 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:
<!-- 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:
<!-- Add descriptive alt text to all images -->
<img src="image.jpg" alt="Descriptive text explaining image content">
Missing HTML Lang Attribute:
<!-- Add to opening <html> tag -->
<html lang="en">
Priority 2: Important Optimizations
Viewport Meta Tag (critical for mobile SEO):
<meta name="viewport" content="width=device-width, initial-scale=1.0">
Charset Declaration:
<meta charset="UTF-8">
Open Graph Tags (for social media sharing):
<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:
<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:
<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:
<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:
python scripts/generate_sitemap.py <directory> <base_url> [output_file]
Example:
# 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:
- Upload sitemap.xml to website root
- Add reference to robots.txt
- 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.
6. Verify and Test
After implementing fixes:
Local Testing:
- Run the SEO analyzer again to verify fixes
- Check that all critical issues are resolved
- Ensure no new issues were introduced
Online Testing:
- Deploy changes to production
- Test with Google Rich Results Test: https://search.google.com/test/rich-results
- Validate schema markup: https://validator.schema.org/
- Check mobile-friendliness: https://search.google.com/test/mobile-friendly
- Monitor in Google Search Console
7. Ongoing Optimization
Regular maintenance:
- Update sitemap when adding new pages
- Keep meta descriptions fresh and compelling
- Ensure new images have alt text
- Add schema markup to new content types
- Monitor Search Console for issues
- Update content regularly

Key Principles
User-First: Optimize for users first, search engines second. Good user experience leads to better SEO.
Unique Content: Every page should have unique title, description, and H1. Duplicate content hurts SEO.
Mobile-First: Google uses mobile-first indexing. Always include viewport meta tag and ensure mobile responsiveness.
Accessibility = SEO: Accessible websites (alt text, semantic HTML, proper headings) rank better.
Quality Over Quantity: Substantial, valuable content ranks better than thin content. Aim for comprehensive pages.
Technical Foundation: Fix critical technical issues (missing tags, broken structure) before advanced optimization.
Structured Data: Schema markup helps search engines understand content and can lead to rich results.
Regular Updates: SEO is ongoing. Keep content fresh, monitor analytics, and adapt to algorithm changes.
Natural Language: Write for humans using natural language. Avoid keyword stuffing.
Validation: Always validate changes with testing tools before deploying to production.
Tips for Maximum Impact
- Start with critical issues: Fix missing title tags and meta descriptions first - these have the biggest impact
- Be consistent: Apply optimizations across all pages, not just homepage
- Use semantic HTML: Use proper HTML5 semantic tags (
<header>,<nav>,<main>,<article>,<aside>,<footer>) - Optimize images: Compress images, use descriptive filenames, always include alt text
- Internal linking: Link to related pages with descriptive anchor text
- Page speed matters: Fast-loading pages rank better
- Test on mobile: Majority of searches are mobile - ensure excellent mobile experience
- Monitor Search Console: Use Google Search Console to track performance and identify issues
- Update regularly: Fresh content signals active, valuable websites
