Frequently Asked Questions

Is SEO Booster really free?
Yes, 100% free. No premium tier, no hidden paywalls, no data collection. Open source and community-driven.
Does it work on Edge?
Absolutely. SEO Booster is a Chromium-based extension, so it works on Chrome, Edge, Brave, Arc, and any Chromium browser.
Does live editing change my actual site?
No. Live edits are client-side only — they modify the DOM in your browser for preview purposes. Your production site remains untouched.
Which pages can I audit?
Any public or locally served web page. Just open the extension panel and it will scan the current page's meta tags, headings, and Open Graph data instantly.
