What is a Website Score?
Learn what the SiteIndex diagnostic score measures, how categories are weighted, and where its limits are.
The short answer
The SiteIndex Website Score is a diagnostic summary of publicly observable SEO, performance, security, accessibility, and technical signals. It is not a Google ranking score.
Step by step
- Open Website Score and enter a public HTTP or HTTPS URL.
- Review the overall score and category scores.
- Open failed and warning checks for specific recommendations.
- Fix the highest-impact issues, then run a new analysis.
Technical details
- The analyzer checks one public page plus limited same-site robots.txt and sitemap resources. It applies category weights described in the methodology.
Common mistakes
- Treating the score as a certification.
- Assuming one page represents an entire site.
- Ignoring the explanation behind a category score.
Limitations
- It does not crawl an entire site, run a real-user performance study, or assess business content quality.
