Chrome extension FAQ
Is the SEO Chrome extension free?
Yes, permanently. Install it and audit any page you visit with no account. Signing in links it to your dashboard so audits are saved alongside your rankings and backlinks.
What does the extension check?
Title tag and length, meta description, heading hierarchy, images missing alt text, internal and external links, canonical tag and indexability — the on-page fundamentals, checked against the page as it actually renders.
Does it work on any website?
Yes, including competitors'. It reads the rendered page, so you can inspect how any site has structured its on-page SEO.
How is this different from the web platform?
The extension audits one page at a time, in place, while you browse. The platform tracks your rankings over time, finds keywords you don't rank for, maps backlinks, scans local map-pack position and reports AI search visibility. Same account, different jobs.
