Overview
Detailed SEO extension provides comprehensive page analysis — meta tags, headings, images, structured data and social cards — with actionable suggestions.
Detailed SEO Extension is a free on-page inspector from the Detailed.com team. One click opens a panel with the page's title and length, meta description, canonical, robots directives, heading outline, images with alt text, links, structured data and hreflang. It does not show backlink or traffic metrics, which keeps it fast and free.
It is the tool to reach for when auditing a page rather than sizing up a results page: it answers whether a page is technically set up correctly, while the Ahrefs and Moz toolbars answer how strong it is.
