Run a JavaScript SEO score
The score focuses on whether crawlers can receive readable HTML, titles, descriptions, headings, and accessible content.
Bare domains use HTTPS and the www hostname by default.
Crawler-readiness
You want a practical technical score, not a generic SEO checklist.
Already live
The site is shipped and you do not want to rebuild with SSR just to help bots.
Prioritize pages
Find pages where crawler-readable text, metadata, or access needs attention first.
How to use the result
- Crawler-readable text
- HTTP status and access issues
- Title, description, headings, and thin-content warnings
Use this score as a technical readiness signal for crawler access, readable content, metadata, and obvious JavaScript SEO issues.
If the score is low
Fix access and metadata issues first, then monitor the site so you can confirm crawler-readable HTML stays healthy.
