📚 Documentation: Updates documentation metadata and social media integration

Code Review

🎯 Overview

This PR addresses the issue of docs previews showing random images by implementing comprehensive Open Graph and Twitter Card metadata. The implementation is well-structured and follows best practices for social media integration.

✅ Strengths

1. Comprehensive Social Media Coverage

   • Proper Open Graph tags for Facebook/LinkedIn sharing
   • Complete Twitter Card implementation with summary_large_image
   • Both use the same templating logic for consistency

2. Smart Fallback Logic

   • Pages can define custom og_image in frontmatter, falls back to default logo
   • Page-specific descriptions fall back to site description
   • Proper title concatenation: "Page Title - Site Name"

3. SEO Enhancements (docs/extra/overrides/main.html:23-31)

   • Added canonical URLs
   • Meta description and keywords tags
   • Author attribution

4. Template Best Practices

   • Uses Jinja2 conditionals to prevent empty attributes
   • Properly extends base template and calls super()
   • Clean, readable structure

🔍 Technical Review

HTML Template Changes (docs/extra/overrides/main.html)

• Lines 6-12: Open Graph implementation is correct and complete
• Lines 14-21: Twitter Cards properly configured with site/creator attribution
• Lines 23-31: Additional SEO metadata is appropriate

MkDocs Configuration (mkdocs.yml)

• No configuration changes were made in the diff, which is correct since the template overrides handle everything

🚨 Minor Issues & Suggestions

1. Image Path Concern (main.html:10,19)

   {{ page.meta.og_image }}{% else %}_static/imgs/ragas-logo.png
   

   The fallback image path _static/imgs/ragas-logo.png should ideally be absolute. Consider using {{ config.site_url }}/_static/imgs/ragas-logo.png for better reliability across different deployment contexts.

2. Potential Missing Image Alt
   While og:image:alt is set, consider adding the same alt text for Twitter Card accessibility.

3. Keywords Optimization (main.html:25)
   The default keywords are comprehensive, but consider if they should be more targeted or if additional page-specific keywords would be beneficial.

🧪 Testing Recommendations

To verify this implementation:

1. Test with Facebook's Sharing Debugger
2. Test with Twitter's Card Validator
3. Check various page types (index, documentation pages) to ensure metadata renders correctly
4. Verify image paths resolve correctly in production

📈 Impact Assessment

Positive Impact:

• ✅ Solves the random image issue in social media previews
• ✅ Provides consistent branding across social platforms
• ✅ Improves SEO with structured metadata
• ✅ Enables page-specific customization

Risk Assessment:

• 🟢 Low risk - metadata-only changes
• 🟢 No breaking changes to existing functionality
• 🟢 Graceful fallbacks prevent empty metadata

🎯 Overall Assessment

This is a solid implementation that directly addresses the stated problem. The code follows best practices for social media metadata and provides a flexible system for page-specific customization. The template structure is clean and maintainable.

Recommendation: ✅ Approve - This PR is ready to merge after considering the minor image path suggestion above.
