Frequently Asked Questions
How does this tool work?
The tool fetches the HTML content of a webpage and analyzes SEO elements including meta tags, heading structure, image attributes, links, Schema markup, and more, scoring against best practices.
Why can't some URLs be analyzed?
Some websites enable CORS restrictions that prevent browser-based fetching. In this case, you can view the page source (Ctrl+U), copy it, and paste it into the "Paste HTML" mode.
Is my data stored?
No. All analysis happens entirely in your browser. We never store, transmit, or log any webpage content or analysis results.
What scoring criteria is used?
Scoring is based on Google SEO best practices, covering meta tags, content quality, technical SEO, social tags, structured data, and more, with each item weighted by importance.
Can this replace SEMrush or Ahrefs?
This tool focuses on single-page on-page SEO analysis for quick checks. For backlink analysis, competitor tracking, and advanced features, professional SEO tools are recommended as a complement.
