Frequently Asked Questions

Common questions about SEO Inspector. Have a question that is not answered here? Contact us and we will help.

No. There is no account. There is no login. There is no Pro tier.

It pretty-prints JSON-LD, validates hreflang, flags canonical and robots conflicts, and copies the whole audit as JSON. None of those three live in Detailed SEO. MozBar paywalls DA/PA and asks for broad host access at install.

Coming in v1.1 behind an optional permission you grant per origin. The v1 popup focuses on what you can read from the DOM with zero permission cost.

Yes. Built from the same source. Chrome, Edge, and Firefox all run the same audit.
