Why this exists: the best-known on-page SEO extension now requires a paid Keywords Everywhere API plan before it will audit anything — its recent reviews are largely complaints about exactly that. SEOAudit Pro reads the page you are on, locally, and needs no key.

- Zero API keys and no third-party services
- Meta title, description, canonical, OpenGraph and Twitter card checks
- H1-H6 heading tree that flags skipped levels

Questions
- Do I need an API key?
- No. Everything is read directly from the page in your browser. There is no keyword API, no account and no quota.
- Why do other SEO extensions ask for one?
- Several rely on paid keyword-data services and stop working without a subscription. This one audits what is actually on the page, so it needs nothing external.
- Does it work on localhost or staging?
- Yes. It reads whatever tab you run it on, including local and staging sites.
- What does Pro add?
- CSV and Markdown export, and white-label reports you can send to clients. The audit itself is free.
