SEO Browser Extensions
Quick SEO data while browsing. See metrics, check redirects, analyze pages without leaving your browser.
Detailed SEO Extension
Clean, fast, shows what matters. One-click access to on-page elements, links, schema, headers. No bloat. Free. Install this one first.
Extension Overload Warning
It's tempting to install every SEO extension. Don't. They slow your browser, clutter your toolbar, and mostly show the same data. Pick 2-3 that fit your workflow. The rest are redundant.
Most importantly: no extension replaces actual SEO work. Seeing a page's DA while browsing doesn't help if you're not building links or creating content.
