What it does
Detailed SEO Extension provides page-level SEO inspection in Chrome and Firefox. It brings metadata, heading structure, structured data, links, images and hreflang references into browser panels and export tools.
Detailed SEO Extension puts the current page's SEO details beside the page in Chrome or Firefox. Its overview brings together titles, descriptions, robots instructions and response information, making it useful when checking a newly published page.
For an image review, open the image panel and export its table to CSV for the content team. Link exports help review destinations and nofollow or sponsored attributes. The heading panel shows the page structure without searching through source code.
On a multilingual page, open Schema > Hreflang to inspect language references, response status and return references. A correct-looking language URL is less useful if it fails or does not point back as expected.
The extension is free forever, with Chrome and Firefox installation links on its official page. It is well suited to investigating a particular page before writing a precise task for a developer or editor.
