Detailed SEO Extension review: our take
Detailed SEO Extension is a free one-click readout of a page's on-page signals: title, meta description, meta robots and X-Robots headers, headings indented by structure, links flagged nofollow or sponsored, images, schema and hreflang with status codes. It also pulls People Also Ask questions from Google results and switches the user agent to Googlebot, and the vendor promises no upsells.
It reads one page at a time and only what is on that page, so link metrics, traffic and keyword volumes are out of scope. The Ahrefs SEO Toolbar covers the same on-page ground for free, adds redirect chain tracing and shows Domain Rating after a free sign-in, with backlinks and traffic from $29 a month on Ahrefs Starter. MozBar's free account offers Domain Authority and Page Authority instead.
What Detailed SEO Extension does
On any page you visit, the extension pulls the title tag, meta description, meta robots and X-Robots HTTP headers, and lists headings indented by structure, links (with nofollow and sponsored flags), images and schema markup. It checks hreflang references and their status codes, links to the site's sitemap, can switch the browser user agent (for example to Googlebot) and extracts People Also Ask questions from Google results. A right-click menu opens the current page or site in Ahrefs, Moz, Majestic, Archive.org, Similarweb, Semrush and other tools, and runs site: searches.
