Best SEO Plugins for WordPress in 2026: 6 Tested and Compared

Every WordPress SEO plugin does the same basic job: it manages the title, description, canonical and schema tags that search engines and AI tools read, builds an XML sitemap, and checks your posts as you write. They differ in what they do before you touch a setting, how much they load, which features sit behind which plan, and what they charge in year two.

We installed six of them on the same test store on 5 October 2026, one at a time, and recorded what each printed on a blog post and a product page, what it loaded, and what it showed after activation. Every plan, price and feature below was read from the developer’s own pages the same day, and every “no” was checked in the plugin’s code or confirmed by the developer.

The short answer

• Best overall: Rank Math. The free version includes a redirect manager, a 404 monitor, five focus keywords (more with a code filter), an llms.txt file and Search Console data. Rank Math PRO costs $95.88 for the first year and renews at $107.88, for every site you own.
• Best for teams that write in Google Docs: Yoast SEO. Premium includes a seat of its Google Docs add-on and checks up to five keyphrases. But the free version left our post with no meta description, and Premium is $118.80 a year per site.
• Best if you want AI credits in the plan: All in One SEO. Basic includes 10,000 AI credits, WooCommerce SEO and the schema builder. It is $49.50 in year one, then $99 a year.
• Best for client sites at a flat price: SEOPress. PRO for unlimited sites is $149 a year, and the developer says it renews at the price you paid while automatic renewal stays on.
• Smallest on disk, and best if you want it done for you: Slim SEO. It is 1.7 MB with no database tables, and it has free redirects, but it cut our description in the middle of a word.

Over three years on one site, the cheapest paid plan of each plugin ranges from $147 (SEOPress PRO) to $356.40 (Yoast SEO Premium). For ten sites of your own, Rank Math PRO stays at $311.64, because it is not priced per site.

How we tested

The store. A WordPress 7.1.2 site with WooCommerce 11.1.2 and the Twenty Twenty-Five theme, running in Docker on our own machine. We measured one short blog post (“How to Care for a Cast Iron Skillet”: two paragraphs and one heading, no image) and one simple product. The store also has three other posts from earlier tests.

The plugins. We tested the free versions on screen: Rank Math 1.0.279, Yoast SEO 28.6, All in One SEO 5.0.2.1, SEOPress 10.3, Slim SEO 4.11.0 and The SEO Framework 5.1.4. Each copy was byte-for-byte identical to the release on WordPress.org.

The method. Before each test we deleted the plugin’s options, post data and tables, so each run started like a fresh install. We activated each plugin alone from the Plugins screen, left every setting at its default, and read the post, the product, the home page and the shop page.

Rank Math. It printed nothing until its account step was dealt with. We measured it twice: before the step, and after setting the one option that its “Skip Step” button sets. The figures shown are from after.

The paid versions. We did not test them on screen. To check whether a feature exists at all, we also searched the code of PureGPL’s own copies of the paid plugins. Five of those files (Rank Math PRO, Yoast SEO Premium, All in One SEO Pro, SEOPress PRO and Slim SEO Pro) contain added lines that bypass the developer’s licence check. They mark a licence or account as valid, answer the calls the plugin makes to the developer’s servers, or point the licence at another server. One fakes a paid account, and one also hides a menu. So every plan placement in this article comes from the developers’ own pages, never from those files.

What this test is not. It is a behaviour test, not a ranking test: no test like this can show that one plugin ranks a page higher than another, and we do not claim it.

All six at a glance

Installs and ratings are from WordPress.org and prices from each developer, both read on 5 October 2026, before tax. Rank Math’s page shows the same figures in dollars or euros depending on where you are.

What each one did out of the box

A WordPress site with no SEO plugin already prints a title and a canonical tag on a post. It prints no meta description, no social tags and no schema. Here is what each plugin added to that same post with its default settings.

Three results stood out.

• Yoast is the only one that does not write a description for you. The tag stays out until you type one, so Google picks its own snippet.
• SEOPress printed no schema on the post at all. In its free version that is by design: it prints WebSite schema on the home page and nothing on posts. The SEO Framework printed WebPage and breadcrumb schema but no Article.
• None of the six added a script or stylesheet to the public page. The cost on the front end is text in the page head, between 1.1 KB and 4.8 KB. The weight that differs is in your admin, shown further down.

On the product page every plugin kept or rebuilt the Product schema that WooCommerce already prints. Rank Math replaced WooCommerce’s Product markup with its own and dropped the breadcrumb markup. SEOPress left WooCommerce’s markup exactly as it was. The other four kept WooCommerce’s Product markup and added their site-wide schema around it.

Setup: the first screen after activation

Rank Math does nothing until you pass its account screen. With the plugin active and the account step untouched, our post had no description, no social tags and no schema from Rank Math. Its code stops the front end until the site is connected or the step is skipped. “Skip Step” is the small button at the bottom left. Press it and the full output appears.

Slim SEO was the only one that opened on a working settings page. All its feature switches were already on (the 404 log is a separate setting, off by default). It also flagged two problems with our store: a full-text RSS feed and no HTTPS.

How each one writes your description

If you do not type a meta description, what the plugin writes by itself is what the page gets. We left the field empty on our short test post.

All in One SEO and SEOPress used the whole of our short post, and they ran the “Seasoning” heading straight into the next sentence. SEOPress’s own panel then marked its description in red as 249 of 160 characters. Slim SEO stopped at exactly 160 characters, mid-word. Rank Math and The SEO Framework cut at a word, which reads best.

Writing and content analysis

How to read the feature tables:

• “Free”: in the free plugin.
• A plan name: that plan and the ones above it.
• “Not listed”: the developer’s pages do not mention it and we did not find it in the code we have.
• “No”: the code or the developer confirms it is absent.

Slim SEO’s paid plans are called Personal, Freelancer and Agency. All three have the same features.

On the same post with the focus keyword “cast iron skillet”:

• Rank Math showed a preview and a “Basic SEO” checklist with one error.
• Yoast gave an orange SEO analysis and a green readability analysis.
• All in One SEO scored the post 79/100 and the keyword 85. When we tried to add a second keyword, it said “You’ve run out of keywords”.

Two notes on the keyword counts:

• Rank Math: the free version allows five focus keywords by default, and a code filter removes the limit. Its own comparison table ticks “unlimited” for free.
• SEOPress: it lets you check any number of keywords for free, but its readability analysis is a single check, words per section.

Weight: on disk, in the database and in your editor

None of the six slowed the public page with scripts. The difference is on your server and in your admin, where you write.

All in One SEO loaded 243 of its own files to open one post, Yoast 48 and Rank Math 24. Slim SEO, SEOPress and The SEO Framework each stayed under 250 KB of JavaScript. That is what your browser loads to open a post for editing. We did not time page loads.

Schema

Rank Math’s free version already lets you pick from 18 schema types per post. Rank Math, All in One SEO, SEOPress and Slim SEO all keep their schema builders on paid plans, each from its lowest one.

Yoast lets you choose the page and article type. Its structured data page talks about building custom schema, but it has no schema builder on any plan: none of its four plugins on our store contains one.

Redirects and 404 errors

This is where the free versions differ most. Rank Math and Slim SEO include a full redirect manager, regex rules and a 404 log at no cost. In Rank Math, the redirect manager and the 404 monitor are modules you switch on.

• Yoast: redirects need Premium, and no Yoast plan has a 404 monitor.
• All in One SEO: its comparison table puts the redirect manager on Pro ($199.50 in year one) and Elite. Its Basic plan card also lists “Automatic Redirects” and “Redirect Monitoring”, so its own page disagrees with itself.
• SEOPress: the free version redirects one post at a time, and the redirect manager is PRO.

Sitemaps

All six built an XML sitemap on our store with no setup. Rank Math’s is at /sitemap_index.xml and returned “not found” at /sitemap.xml. SEOPress sends both addresses to its own /sitemaps.xml. Yoast, All in One SEO, Slim SEO and The SEO Framework answered at /sitemap.xml. The SEO Framework listed 22 URLs in a single file.

Local SEO and WooCommerce

Yoast: Premium now includes the Local, Video and News SEO plugins. WooCommerce SEO is a separate plan at $178.80 a year, and it includes Premium.

All in One SEO: WooCommerce SEO is on Basic, but Local SEO starts on Plus ($99.50 in year one for three sites).

Rank Math: the free version covers one business location and basic product schema. Multiple locations and extra product fields such as GTIN are PRO.

AI features and llms.txt

An llms.txt file is a plain list of your most important pages for AI tools. Rank Math, Yoast and All in One SEO all generate one in their free versions, and all three leave it off until you switch it on. We switched each on.

• Rank Math served the file live. It listed our posts with their descriptions, our pages, our product and the sitemap.
• Yoast wrote a 938-byte file to the site’s root folder and scheduled a weekly refresh. It listed one of our four posts. Yoast builds the list from its own index of the site, which it fills when you run its “SEO data optimization”. We had not run it, so only the one post we had opened was in the index.
• All in One SEO wrote a 3,971-byte file. Its post descriptions carried raw shortcodes from older test posts on our store, such as “[content-egg-block template=price_comparison]”. Those belong to plugins that were switched off, so WordPress could not remove them. The file also had the same glued “rust.SeasoningRub”.

The AI features are sold in different ways:

• Rank Math: a separate Rank Math AI subscription.
• Yoast: included in Premium.
• Slim SEO: free, with your own API key.
• All in One SEO: AI credits, 10,000 on Basic and 200,000 on Elite.
• SEOPress: your own API key, or credits from $19 a month.

Internal links, Search Console and rank tracking

Rank Math: the free version shows Search Console data inside WordPress, keeping 90 days of it. Rank tracking starts on PRO with 500 keywords, shared across all your sites.

All in One SEO: Search Statistics and its rank tracker need Elite ($299.50 in year one, $599 after).

SEOPress: rank tracking is a separate service, SEOPress Insights, at $99 a year per site for 50 keywords.

Technical SEO tools

Switching from another SEO plugin

The other five can all import your titles and descriptions from Yoast. The gaps are elsewhere:

• Yoast: it has no importer for SEOPress, although its free product page says it migrates SEOPress data.
• All in One SEO and The SEO Framework: each imports from three plugins (Yoast, Rank Math and SEOPress).
• Rank Math: it has no importer for The SEO Framework or Slim SEO.

Run only one SEO plugin at a time. Each printed its own title, description and schema tags in our test, so two would give you duplicates. Deactivate the old one once the import is done.

Agencies and client sites

Rank Math PRO is for sites you own. Its pricing page says “Client websites are excluded”, so client work needs Business or Agency.

The other five paid plugins allow client sites within each plan’s site count:

• SEOPress: 1, 5 or unlimited.
• Slim SEO: 1, 10 or unlimited, but its page says unlimited “does not apply to enterprises, hosting providers, SASS companies, site maintenance providers or similar”.
• All in One SEO: 1, 3, 10 or 100.
• The SEO Framework: 2, 20 or 200.
• Yoast: one subscription per site.

Support and refunds

Every plan and what it renews at

Rank Math sells its plans by the month but bills them yearly (7.99, 24.99 and 54.99 a month in year one, then 8.99, 27.99 and 64.99). The SEO Framework does the same at 7, 17 and 27 a month. The yearly figures above are those monthly prices times twelve. Rank Math’s Agency card says 500 client sites, but its own FAQ says Business and Agency cover “100 client & personal websites”; we used the card. Yoast takes 5% off at five subscriptions and 15% at ten when they are bought together. Yoast and The SEO Framework show one price with no first-year discount, so we have taken that as the renewal price.

Three years on one site

All in One SEO is the second cheapest in year one, but over three years it falls behind SEOPress and Slim SEO, because Basic doubles to $99 at renewal. Its pricing page says so: “Special introductory pricing, all renewals are at full price.”

Three years on ten sites

The Yoast row is before its bulk discount. At ten subscriptions bought together, 15% off brings three years to $3,029.40, if the discount carries through each renewal.

The top plan, three years, per site

The six, one by one

1. Rank Math

Who it suits: almost anyone. It gives away more than any other free version: redirects, a 404 log, five focus keywords, local schema for one location, llms.txt, IndexNow and Search Console data. PRO covers every site you own for $95.88 in the first year and $107.88 after that.

What we saw: after we skipped the account step, it wrote a 155-character description, six Open Graph and five Twitter tags, and BlogPosting schema.

The catch: nothing works until you connect an account or press “Skip Step”. It loaded 1,400 KB of JavaScript in the editor. Client sites need Business ($299.88 in year one).

👉 Rank Math SEO Pro on PureGPL ($4.99) and our Rank Math review.

2. Yoast SEO

Who it suits: writers and editors. The free version scores every post for SEO and readability. Premium checks up to five keyphrases (“Synonyms and word forms count”), includes a seat of the Google Docs add-on, and now includes the Local, Video and News SEO plugins. It has the most installs of the six, 10 million+.

What we saw: Article and breadcrumb schema, but no meta description until we typed one. It was also the second heaviest in the editor, at 3,635 KB of JavaScript.

The catch: it is priced per site, so five sites cost five times as much, less a 5% bulk discount. Redirects need Premium, and no plan has a 404 monitor.

👉 Yoast SEO Premium on PureGPL ($4.99) and our Yoast SEO Premium review.

3. All in One SEO

Who it suits: one site that wants WooCommerce SEO, a schema builder, up to 10 focus keywords and 10,000 AI credits on the lowest plan.

What we saw: it was the heaviest of the six: 25.1 MB on disk, nine database tables, 4.8 KB in the page head and 243 files in the editor.

The catch: every plan doubles at renewal. Redirects and the 404 monitor need Pro, and Search Console data needs Elite. The refund window is 14 days.

👉 All in One SEO Pro on PureGPL ($4.99) and our All in One SEO review.

4. SEOPress

Who it suits: agencies and anyone with many sites. One price covers unlimited sites, client sites are allowed on every plan, and white label is free through code, with a settings screen in PRO. The pricing page says the price you pay is your renewal price “Forever”, except for special promotions and as long as automatic renewal stays on.

What we saw: the second smallest head output (1.7 KB) and only 89 KB of editor JavaScript. But it printed no schema on our post, and its description ran the whole post together.

The catch: the free version is thinner than it looks:

• schema, breadcrumbs and the redirect manager are PRO;
• llms.txt is PRO, although its WordPress.org page lists it among the free features;
• since version 9.6 the free plugin loads promotions from seopress.org and shows “Get PRO” boxes, although its WordPress.org page says “no upsells in admin”.

👉 SEOPress Pro on PureGPL ($4.99) and our SEOPress Pro review.

5. Slim SEO

Who it suits: people who want SEO handled and forgotten. It opened on a settings page with its feature switches already on. It is 1.7 MB with no tables and added 1.1 KB to the head. Redirects, regex rules and a 404 log are free.

What we saw: Article, WebPage, WebSite, Organization and breadcrumb schema on our post, from a 1.7 MB plugin.

The catch: it has no focus keyword field and no content analysis without Pro, and it cut our description inside a word. Slim SEO Pro is $59 a year for one site.

👉 Slim SEO Pro on PureGPL ($3.49) and our Slim SEO Pro review.

6. The SEO Framework

Who it suits: people who want a lean plugin. It loaded the least JavaScript in the editor (63 KB), has no database tables, and has the highest rating of the six, 4.9 from 379 ratings. Paid features come from extensions, from $7 a month paid yearly for two sites.

What we saw: a 156-character description cut cleanly at a word, breadcrumb and WebPage schema, but no Article schema and no focus keyword field. It stayed on the Plugins screen after activation.

The catch: WordPress.org showed its last update in December 2025, and it was marked as tested up to WordPress 6.9.9, not the current 7.1.2. It has no redirect manager (only a 301 field on each post), no 404 monitor and no llms.txt. PureGPL does not sell it.

Which one to choose

What other lists get wrong

We read the pages that rank for this search today and checked their claims against the developers’ pages on 5 October 2026. These were the errors that change a decision:

• Yoast: “A single-site license starts at $89 per year.” (aioseo.com). Yoast SEO Premium is $118.80 a year. wpcreative.com.au gives $99. Neither is today’s price.
• Yoast: “you have to buy them as separate plugins or the full bundle”, of video sitemaps, local SEO and WooCommerce SEO (aioseo.com). Premium now includes Local, Video and News SEO. Only WooCommerce SEO is a higher plan.
• Rank Math: “A single-site license starts at $59 per year.” (aioseo.com; wpcreative.com.au also gives $59). Rank Math has no single-site plan. PRO is $95.88 in year one for every site you own.
• “The Pro plan starts at $49.50” for All in One SEO (aioseo.com, its own page). $49.50 is Basic. The plan called Pro is $199.50 in year one and $399 after.
• “$39 … on an unlimited number of sites” for SEOPress (nickschaeferhoff.com). Unlimited is $149 a year. The cheapest plan is $49 for one site.
• SEOPress shows “no ads or upsell banners in your WordPress dashboard” (keytomic.com; onelittleweb.com says much the same). The free plugin has shown PRO promotions fetched from seopress.org since version 9.6.
• “No Built-In Redirect Management” in Slim SEO (onelittleweb.com). The free plugin has a Redirection tab with regex rules and an optional 404 log.
• A paid 404 monitor in Yoast (keytomic.com). No Yoast plan has a 404 monitor.
• All in One SEO’s free version has “a schema generator, rank tracking, internal linking automation” (zapier.com). The schema generator is paid, rank tracking is Elite and Link Assistant starts on Pro.

Tools that pair with an SEO plugin

An SEO plugin handles tags, sitemaps and on-page checks. Three other tools cover what it does not:

• Google Search Console is free. It shows which searches your pages appear for, and no plugin replaces it.
• Internal links: Link Whisper Pro suggests links between your posts as you write.
• Extra schema types: Schema Pro adds schema site-wide. See our Schema Pro review.

On PureGPL

We sell the Pro versions of five of these plugins:

• Rank Math SEO Pro, Yoast SEO Premium, All in One SEO Pack PRO and SEOPress Pro at $4.99 each;
• Slim SEO Pro at $3.49.

They are one-time payments, or part of a membership.

What a GPL copy does and does not include

WordPress plugins are licensed under the GPL, which lets anyone share the code. A copy from PureGPL is the plugin’s code. It is not a licence with the developer.

What that means in practice:

• Developer support: you do not get the developer’s support.
• Hosted services: anything that runs on the developer’s servers is not part of a GPL copy: rank tracking, AI credits and AI link tools, Search Console reports through their account, SEOPress Insights.
• On-site features: schema, redirects, sitemaps, WooCommerce and local settings run inside WordPress, so they are in the file.
• Updates: they come from us.
• Licence check: as noted in “How we tested”, our paid files contain added lines that bypass the developer’s licence check, so they run without the developer’s key. They are not the developer’s untouched files.

If you need the hosted services, the developer’s support or an untouched file, buy from the developer.

Frequently asked questions

What is the best SEO plugin for WordPress?

For most sites, Rank Math: its free version has the most, and PRO covers every site you own for one price. Yoast suits teams that write in Google Docs, and SEOPress suits agencies with client sites.

What is the best free SEO plugin for WordPress?

Rank Math, for its free redirects, 404 log, five focus keywords by default and llms.txt. Slim SEO is the best free choice if you want no settings at all. See our best free SEO plugins.

Is Rank Math better than Yoast?

Rank Math’s free version does more: Yoast’s has no redirects and writes no meta description by default. Yoast Premium adds five keyphrases and a Google Docs add-on. Our full test is in Rank Math vs Yoast SEO.

Can I use two SEO plugins at once?

Not at once. Each one we tested printed its own title, description and schema tags, so two give you duplicates. Import your settings into the new one, then deactivate the old one.

Do I need an SEO plugin at all?

WordPress alone prints a title, a canonical tag and a basic sitemap. On our test post it printed no meta description, no social tags and no schema, which is what these plugins add.

Do SEO plugins slow down a site?

None of the six added a script or stylesheet to the public page in our test, which is what usually slows a page down; we did not time page loads. They differ in the admin, from 63 KB of JavaScript in the editor (The SEO Framework) to 3,995 KB (All in One SEO).

Which SEO plugin has llms.txt?

Rank Math, Yoast and All in One SEO generate one in their free versions, off by default. SEOPress has it in PRO.

Can an SEO plugin get me to the top of Google?

No. It makes sure search engines can read your pages correctly. Ranking depends on whether the page answers the search better than the others, and on who links to it.
