Does it crawl or submit my website?

No. It analyzes only text you provide and neither fetches URLs nor submits them to search engines.

Does a clean audit guarantee rankings or rich results?

No. Search engines decide crawling, indexing, ranking and rich-result eligibility.

Is generated JSON-LD valid for every case?

No. Templates are editable starting points; verify visible content, required fields and current policies.

Are drafts uploaded?

No. Generation, extraction, validation and export run in this browser.

Keep working with other focused browser utilities.
