It reads the public response.
Web Doctor analyses publicly accessible HTML, response headers and a small selection of public technical SEO files. It does not sign in, bypass access controls or crawl an entire website.
It does not guarantee rankings.
The score describes only the deterministic checks shown in the report. Search visibility also depends on relevance, competition, content quality, reputation, crawling and many systems this tool cannot observe.
It does not replace Search Console.
Web Doctor cannot show Google’s indexing decisions, search queries, manual actions, crawl history or submitted-sitemap status. Use Google Search Console for information available only to a verified site owner.
It sees initial HTML.
Some websites add metadata or content only after JavaScript executes. Those values may not exist in the server’s initial HTML response and can therefore be absent from this report. Web Doctor also does not measure real-user Core Web Vitals.
