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

SEO Pro Extension is a free browser extension that shows a page's main SEO data in seven tabs: overview, headings, status, links, images, schema and social. The overview covers the title, meta description, canonical, meta robots, word count and Core Web Vitals field data, and the icon flags noindex pages and canonicals pointing elsewhere. It is made by MarketingSyrup, which sells SEO courses.

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

No rating on record, but nothing to set up: the icon itself flags noindex pages and canonicals pointing elsewhere.

Who SEO Pro Extension is for

  • Fits if you size up a prospect's site in a few clicks during an audit
  • Works for checking whether a backlink on a page is followed

Who it is not for

  • Not for you if you want keyword, ranking or backlink data, as it has none
  • Watch out: Core Web Vitals are mobile field data only, and pages without enough Chrome data show site-wide figures or nothing
  • Too light for whole-site audits, since it checks one page at a time
  • Skip it if you browse in Safari or Edge, as only Chrome and Firefox are listed
  • Watch out: the store shows the last update as November 20, 2024, and the developer hasn't identified itself as a trader, so EU consumer rights don't 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

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

What this rests on. SEO Pro 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.
