Tips & Best Practices
Always include a title tag between 30-60 characters for optimal search engine display.
Meta descriptions should be 50-160 characters and include your primary keyword.
Add Open Graph tags (og:title, og:description, og:image) for better social media sharing.
Include a Twitter Card type (summary_large_image recommended) for rich Twitter previews.
Use Advanced Analysis mode for a complete picture - Quick Check only validates meta tags.
Export reports as JSON for detailed records or CSV for spreadsheet-friendly summaries.
Check the Security tab to ensure HTTPS is properly configured and security headers are in place.
Re-scan after making changes to verify improvements in your SEO score.
