Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.6
GPA, above 51 of the 81 other SEO plugins and apps we grade
SEOKEY is a WordPress SEO plugin from the French agency SeoMix. It audits all of a site's content and technical setup, ranks the fixes by priority, and applies a set of technical clean-ups automatically. It also manages titles, meta descriptions, redirects, schema markup and image alt text.
To get you started, here are 9 things to know about SEOKEY, taken from its own pages and our grades.
It applies fixes by itself, but you still install, audit and connect Search Console.

SEOKEY is a WordPress plugin that audits a site and applies technical SEO fixes automatically, with schema, redirects and an alt text editor.

The report card
Best for automatic technical SEO fixes on WordPress
SEOKEY is a WordPress plugin that audits a site and applies technical SEO fixes automatically, with schema, redirects and an alt text editor. The free edition covers that, and the Search Console link and 404 monitoring need a paid licence.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | $49 a year for one site (about $4.08 a month, ex-VAT), under 60% of the cheapest quarter of WordPress SEO plugins ($7.99). Five sites are $99 a year. |
| Free plan and trial | B | A free edition on WordPress.org with the audit, automatic fixes, redirections and the alt text editor, which one site can use. |
| Features | C | Audit, automatic fixes, content advice, redirects and 404s, schema and a Search Console link. The Search Console link, 404 monitoring and traffic advice need a paid licence. |
| Ease of use | C | No store rating on record. It applies fixes by itself, but you still install, audit and connect Search Console. |
| Platforms and integrations | C | WordPress only, with Search Console, WooCommerce and Yoast named. |
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 SEOKEY is for
- Fits if you run WordPress and want technical fixes applied for you
- Works for owners of several sites, with 5 sites at $99 a year
Who it is not for
- Not for you if your site is not on WordPress, since it only runs there
- Tight if you stay free: Search Console, 404 monitoring and traffic advice need a paid licence
- Watch out: prices are ex-VAT and per year
- Watch out: the WordPress.org page says the free plugin was not tested with the last three major WordPress releases
Good to know
Good for
- WordPress owners who want guidance on what to fix next
- People moving from Yoast SEO, which SEOKEY can import from
- Agencies covering many client sites under one license
Worth knowing
- Runs only inside WordPress.
- Prices are listed ex-VAT and per year.
- Search Console connection, 404 monitoring and priority support need a paid license.

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
To replace SEOKEY you would be making search volumes for millions of keywords, gathered and kept up to date. That is not a weekend's work, with an AI app builder or without one.
It costs $49 a year.
What you could make
- Schema markup and internal linking: an app builder makes these well.
What you could not
- Search volumes for millions of keywords, gathered and kept up to date.
- A crawler that checks every page of a site.
What this rests on. SEOKEY’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.
