Part 01 · Overview

Welcome

What it is, who it suits, its grades and the ten things to know first

3.0

GPA, above 17 of the 34 other SEO browser extensions we grade

Detailed SEO Extension is a free browser extension from Detailed.com, the SEO site run by Glen Allsopp, that shows a page's title, meta description, robots directives, headings, links, images and schema in one panel. It also adds right-click shortcuts that open the current page in Ahrefs, Semrush, Moz and other tools. The Chrome Web Store now lists Ahrefs Pte. Ltd. as its publisher.

To get you started, here are 7 things to know about Detailed SEO Extension, taken from its own pages and our grades.

No rating on record, but there's nothing to set up: install it, open a page, click the icon and the panel is there.

The report card

Best for one-click page checks in Chrome or Firefox

Detailed SEO Extension shows a page's title, meta description, robots rules, headings, links, images, schema and hreflang in one panel, for free, with right-click links out to Ahrefs, Semrush and Moz. It looks at one page at a time and has no search volumes, rankings or backlink data of its own, so the numbers still have to come from another tool.

Platforms and integrationsCChrome and Firefox extensions, so computers only, with no Safari or Edge version named. The Ahrefs, Semrush, Moz and Majestic links open those sites; no data is pulled in from them.
Grade point averageVery good, out of 4.03.0

An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.

Who Detailed SEO Extension is for

  • Fits if you check titles, headings and schema on single pages and don't want to read the source
  • Works for checking hreflang on a multi-language site, alternate by alternate

Who it is not for

  • Skip it if you want search volumes, rankings or backlinks, as it has none of its own
  • Too light for whole-site audits, since it inspects one page at a time
  • Not for you if you browse in Safari or Edge, as only Chrome and Firefox are listed
  • Watch out: the changelog's last entry is December 2024, though both stores show an update in 2026, and the interface is English only

Keep it, or make your own?

Whether this is something you could build for yourself with an AI app builder, and what you would give up.

Keep it

Detailed SEO Extension is free, so making your own would save you nothing.

And it is not the kind of software a weekend replaces.

What you could make

  • Schema markup: an app builder makes this well.

What you could not

  • A crawler that checks every page of a site.
  • It plugs into other products, Ahrefs, Semrush and Moz among them.

What this rests on. Detailed SEO Extension’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
