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

Website SEO Checker is Sitechecker's free Chrome extension for checking the page in front of you: status code, metadata, canonical and indexing rules, headings, keyword density, links, hreflang, images, structured data and page speed. Signing in to a Sitechecker account with Google Search Console connected adds clicks, impressions and top queries for the page, plus issue tracking and change monitoring.

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

No rating on record, but nothing to set up for the page checks: install it and open the panel on any page, with no sign-up.
From our grade for ease of use

The report card

Best for on-page checks with your Search Console figures

Website SEO Checker is Sitechecker's free Chrome extension for the page you're on: status code, tags, indexing rules, headings, keyword density, links, hreflang, schema and page speed. It checks one page at a time, whole-site crawls are a separate Sitechecker product, and the Search Console figures only show once you're signed in to a Sitechecker account.

ToolGPA report cardWebsite SEO CheckerGraded Oct 23, 2026
SubjectGradeComment
Value for moneyAFree from Sitechecker, with no paid tier for the extension and no sign-up for the on-page checks.
Free plan and trialAFree outright: every on-page check works with no account. Search Console figures and change monitoring need a Sitechecker login, and the listing doesn't say whether a free account covers them.
FeaturesCStatus code, title, description, canonical, robots rules, headings, keyword density, links with follow status, image alt text, hreflang, schema and mobile and desktop speed. The gap the listing names: one page at a time, with site crawls a separate product.
Ease of useBNo rating on record, but nothing to set up for the page checks: install it and open the panel on any page, with no sign-up.
Platforms and integrationsCChrome only, so computers only. It reads Search Console and Google Analytics 4 data through a Sitechecker account, and nothing else is listed.
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 Website SEO Checker is for

  • Fits if you check a page's tags, indexing rules and hreflang without opening its source
  • Works for Sitechecker users who want a page's Search Console clicks and queries beside it

Who it is not for

  • Too light for whole-site audits, as it checks one page and site crawls are a separate Sitechecker product
  • Tight if you won't make a Sitechecker account, since Search Console figures and monitoring need one
  • Not for you if you browse in Firefox, Safari or Edge, as it's listed for Chrome only
  • Watch out: the developer hasn't identified itself as a trader, so EU consumer rights don't apply

Good to know

Good for

  • Quick on-page checks of any page while browsing
  • Sitechecker customers who want Search Console data beside the page
  • Checking hreflang setups on international sites

Worth knowing

  • It checks one page at a time; whole-site crawls are a separate product on the Sitechecker platform.
  • Search Console insights and issue monitoring work only when logged in to a Sitechecker account.
  • It is listed for Chrome only.
  • The Chrome Web Store notes the developer has not identified itself as a trader, so EU consumer rights do not apply.

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

Website SEO Checker 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.
  • Speed tests run from real browsers on a schedule.

What this rests on. Website SEO Checker’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.
