Frequently Asked Questions
Q: Why does the analysis fail for some websites?
A: Many websites block automated requests or browser-based scraping via CORS policies. Our tool uses the AllOrigins proxy to bypass these, but extremely secure sites may still block the request.
Q: How is the SEO score calculated?
A: The score is a weighted average of several factors: Title presence and length (20%), Meta description presence and length (20%), H1 uniqueness (15%), Heading structure (10%), Image alt coverage (15%), and link availability (10%).
Q: Does this tool support SPA or React apps?
A: This tool parses the raw HTML returned from the server. If your site relies entirely on client-side JavaScript to render content (like some SPAs), this tool will only see the initial empty shell. For better results, use SSR (Server-Side Rendering).
