- A Defined Path From Triage to EvidenceQuick extension outputs point to the next check, and questions that require source code, headers, Search Console, logs, or a crawler go straight to those systems. That path keeps every finding reviewable and documented. Compared with using one browser extension as a complete audit.

Frequently Asked Questions
Should a team consider Open SEO Stats for Firefox safe?
In our experience, browser extensions from reputable sources that focus on public page data are generally safe to use, and Open SEO Stats does not require you to log into your site's backend or provide sensitive credentials.
Mozilla lists access to website data, tabs, downloads, and download history, so test the extension in a controlled browser profile and review the permissions it requests during installation to confirm they align with your firm's security policies.
Which Open SEO Stats outputs can be verified directly?
Fields taken from the page, such as titles, headings, links, and canonical tags, can be checked against source code or the rendered document, and the extension's output is well suited to spotting trends and running preliminary audits.
Third-party estimates may differ from primary systems, so for high-stakes decisions, cross-reference them with Search Console, logs, headers, or a deep-dive technical crawl.
Can Open SEO Stats replace a technical SEO audit?
No. It is a page-level triage tool for quick verification and discovery, not a site-wide audit system. It does not crawl the full site, expose Google-selected canonical decisions, or verify a legal identity. It is the first step in a process, used to flag areas that need further investigation.
Does Open SEO Stats report AI citations or model training data?
No. Open SEO Stats reports page-level fields such as titles, meta tags, headings, links, and canonical elements. Tracking AI mentions takes a separate process that records the model, query, date, locale, and repeated observations.
