SEO Pro Extension report card
Very good · out of 4.0 · graded Oct 23, 2026
Best for on-page checks in seven tabs
SEO Pro Extension shows a page's tags, word count, Core Web Vitals, status and redirects, headings, links, images, schema and social preview in seven tabs, free on Chrome and Firefox. It has no keyword, ranking or backlink data, its Core Web Vitals are mobile field data only, and the store shows its last update as November 2024.
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 SEO Pro Extension 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 SEO Pro Extension, or make your own?
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.
