AI plugins for WordPress SEO: 7 options and what they really do on their own

There are two kinds of AI plugins for WordPress SEO. The first kind writes a title or description when you press a button. The second kind chooses which pages are up next and applies the improvement itself. Most well-known plugins belong to the first kind. That is not a problem, as long as you know you still have to start the work.

This article covers seven options. For each plugin you read what the AI does without you being there, because that is where the difference is. Prices are from October 2026 and come from the plugins’ own pricing pages.

Looking for a comparison of the regular features, such as sitemaps, schema and redirects? That is in the best WordPress SEO plugins.

Current prices are on the pricing pages of Yoast, Rank Math, Rank Math Content AI, SEOPress and AIOSEO.

1. Yoast SEO Premium: the AI waits for you

Yoast Premium has three AI features. AI Generate suggests a title and description. AI Optimize suggests improvements to your text. The AI Bulk Editor drafts for many pages at once.

For all three: you click, the AI suggests, you approve. Nothing ever lands on your site that you have not seen. That is the safest approach there is.

The downside shows after a few months. You have to know which page is up next. You have to log in. And you have to keep doing it. Yoast does not tell you that your gutter repair page sits at position 9 and deserves a better title.

Fits you if you are in WordPress yourself every week and do not want to hand anything over. If you run an online store, also read WooCommerce SEO.

2. Rank Math PRO: automatic internal links

The AI feature that stands out in Rank Math PRO is AI Link Genius. You make a list of keywords and the page they should link to. Rank Math finds those words in your posts and links them. By default, at most three per post.

If you turn on “Auto-link on publish”, it happens with every new post by itself. Every link can be undone.

It works on words. The plugin checks whether the word is in the text, not whether the link helps the reader at that spot. So keep your list short and specific. “Gutter replacement” works. “Roof” does not.

Fits you if you have several sites of your own and many posts with few links between them.

3. Rank Math Content AI: writing help as a separate subscription

Content AI is a set of more than forty writing tools inside Rank Math. Titles and descriptions in bulk, alt text, a blog outline. It is a separate subscription next to PRO.

It is handy if you write a lot. It does not take choosing and checking off your hands.

4. SEOPress PRO: fills empty fields on publish

SEOPress works with your own AI key. You connect an AI service and SEOPress uses it to write titles, descriptions and alt text.

There is one automatic mode. If you publish a post with an empty title or description field, SEOPress fills it at that moment. A field you filled in yourself is left alone. It does not tackle existing pages on its own.

There is no approval step in that automatic mode. So read the first ten results.

Fits you if you manage many sites and want the lowest price. For $149 a year you use it on unlimited sites.

5. AIOSEO: rewrite with one click

AIOSEO includes AI credits with every paid plan. With “Optimize with AI” the plugin rewrites your title, description, heading and body in one click.

Be careful with that last one, the body. An AI that rewrites your running text strips out your own voice. Let it do the title and description and keep the body in your own hands. What to watch for in AI-written text is in AI content that sounds human.

Also check the price in year two. Basic costs $49.50 in the first year and $99 after that.

6. SEO.AI Publisher: new articles, automatically

SEO.AI is a platform that writes articles. The SEO.AI Publisher plugin puts those articles into your WordPress as new posts. You can have them published automatically, saved as drafts or reviewed first.

This is truly automatic, but it is about new content. The plugin does not improve your existing pages: according to its WordPress.org description it supports regular posts.

We are cautious about automatically publishing whole articles. An article contains facts about your business and your field. Someone has to check them. The comparison with GreatCompany is on SEO.AI alternative.

Fits you if you mainly want more content and have someone who reads everything.

7. GreatCompany: chooses, applies, measures

The GreatCompany plugin works differently from the first five. It does not write on request. It works on a fixed rhythm.

Every week GreatCompany scans all your pages. Connect Google Search Console and your numbers are added. GreatCompany picks up to five improvements that pay off most right now and applies them on Monday: titles, meta descriptions, internal links and alt text.

Per item you choose one of three modes: Automatic, Approve first or Off. With Approve first you get an email with a Yes and a No button. The title and description of your homepage always come to you for approval first. Blog posts are off by default.

A few things we cared about when building it:

• Every change can be undone with one click.
• The plugin never changes the URL of a page.
• Your theme and layout stay as they are.
• No WordPress password goes into GreatCompany. You connect with a Connect button.
• After four weeks you see per change what it delivered in clicks.

GreatCompany works next to Yoast, Rank Math, SEOPress and AIOSEO. It writes the new title into the field of your existing plugin. So you do not have to switch.

What GreatCompany does not do: your theme, your speed or broken links to other sites. Those items go on a work list with an explanation for your web developer. And on pages built with a page builder such as Elementor, GreatCompany improves the title and description but leaves the text and images alone. More on page builders is in Elementor and SEO.

Automatic will cost $99 a month as an introductory price. Everything about how it works is on GreatCompany for WordPress.

Fits you if you have a WordPress site and no time to log in every week.

Which question should you ask yourself?

What happens on my site if I do nothing for a month?

With Yoast, Content AI and AIOSEO the answer is: nothing. Those plugins are tools. Good tools, but they sit still if you do not pick them up.

With Rank Math and SEOPress, something happens with new posts. Your existing pages stay as they were.

With SEO.AI, new articles are added.

With GreatCompany, up to twenty improvements have been applied to your existing pages after a month.

None of those answers is wrong. It depends on what you want. If you like being at the controls yourself, Yoast Premium serves you well. If you want the work gone, you need a plugin that takes initiative. How such software works and where you draw the line is in AI SEO agent.

Combining is fine, doubling is not

Never install two plugins that both write your title and sitemap. Yoast next to Rank Math gives duplicate titles and two sitemaps.

A plugin that works through your SEO plugin can run next to it. GreatCompany with Yoast is no problem, because GreatCompany fills Yoast’s fields.

Keeping or replacing Yoast is covered in Yoast alternative: the options, and when adding something is smarter than switching.

What no plugin does for you

A plugin does not make your site better than your offer. If your service page has no price, no service area and no answer to the customer’s question, the best AI writes a nice title above it. The visitor clicks, reads and leaves.

So the foundation stays yours. If you want a person’s help with it, hiring a WordPress SEO specialist covers what that costs. The five settings and four recurring tasks that belong to it are in WordPress SEO. The wider story of what you can automate is in automating SEO with AI.
