All in One SEO vs Yoast vs Rank Math: Three-Year Cost and What the Free Plugins Include

In all in one seo vs yoast, the choice is mostly about licence shape and renewal cost, because all three plugins handle the basics. Yoast suits one site and plain guidance. All in One SEO fits several sites on one plan, and Rank Math works best on sites you own, with a strong free version. If your current plugin already outputs correct titles, canonicals and sitemaps, keep it.

Feature lists tell you little here. This guide checks what you can verify: what each plan costs by year three, what the free download contains, and how big each plugin is.

How this guide was checked: prices come from each vendor's own page on 6 November 2026, before tax. Plugin data comes from WordPress.org, and we downloaded each free plugin to read its files. We did not run a speed test or review the paid versions hands-on. This page has no affiliate relationship with any of the three.

Who publishes the comparisons you are reading

Most pages on this topic have a stake in the answer. All in One SEO publishes its own comparison of the three, and its owner also owns WPBeginner, a popular WordPress site that compares them too. Awesome Motive lists both in its portfolio [4]. That does not make their advice wrong, but it is worth knowing before you trust a verdict.

All in One SEO vs Yoast vs Rank Math at a glance

Install counts and ratings show popularity, not quality [6] [7] [8]. All three were updated within the ten days before our check.

What each plugin costs over three years

The vendors quote prices differently, which is why a simple "cheapest" label misleads. Rank Math quotes euros per month billed yearly. Yoast and AIOSEO quote dollars per year, and AIOSEO leads with a first-term discount.

These totals are Anobee's sums from listed prices [1] [2] [3]. Rank Math's year one uses its November anniversary sale of €5.59 a month, so that first figure will change. Its renewal is €8.99 a month. Prices exclude tax, and the Rank Math total is in euros, so do not compare it to the dollar totals directly.

The renewal gap decides all in one seo vs yoast

AIOSEO looks far cheaper in year one, at $49.50 against $118.80. Its pricing page says renewals are at full price, so the gap shrinks to $99 against $118.80 from year two [3]. Yoast's price also includes its Local, Video and News SEO plugins [2].

If you run one site and would use those plugins, Yoast is the better value. If you would not, AIOSEO saves about $20 a year after the first.

AIOSEO's plans scale by site count:

Yoast adds extra seats for $5 a month each [2]. Check how it prices extra sites before you buy for several.

Rank Math's licence boundary

Rank Math PRO is the cheapest option over time only if you own the sites. Its pricing page says you can use it on unlimited websites you own, and that client websites are excluded [1]. A freelancer who uses PRO on client builds is outside those terms. Business renews at €27.99 a month, and Agency at €64.99.

What the free plugins actually include

We downloaded the current free version of each plugin on 6 November 2026 and read its files and readme. No plugin was installed or run.

The pattern matches what the vendors say. Rank Math gives away the most. On free features, all in one seo vs yoast is a close call, since both keep redirects behind a paid plan. Yoast keeps its free version focused on guidance, and that plain advice matters for a team where not everyone knows SEO. AIOSEO keeps its strength in the paid modules, so judge it on those.

All three files also include llms.txt support. Do not pick a plugin for that, because Google says you can ignore such files for Google Search [9]. A green light in any of them means the plugin's own checks passed, not that the page is good. Our on-page SEO checklist covers what they cannot judge.

How big each plugin is

AIOSEO's unzipped files are about twice the size of Rank Math's. That is a fact about the download, not about speed. Much of a plugin never loads on a given page, so size on disk does not tell you what visitors wait for. We did not run a controlled speed test, so nothing here is evidence on page speed. Be wary of any comparison that claims one plugin is faster without showing a test.

Which one should you choose?

• One site, less to think about: Yoast.
• Several sites you own: Rank Math PRO, or its free version if that covers you.
• Client sites: Rank Math Business, or a multi-site AIOSEO plan. Compare both at renewal price.
• Redirects for free: Rank Math.
• Local or Video SEO on one site: Yoast Premium.
• A plugin that already works: stay put. Switching rarely fixes a ranking problem.

A page that is not ranking is seldom held back by which of these three you installed. Google says third-party tools cannot access its internal ranking data, so no plugin score is a ranking signal [5].

Why are you leaving Yoast?

Many readers arrive already planning to switch. The reason changes the advice:

• Renewal cost: Rank Math PRO saves real money on personal sites. If you use the plugins Yoast bundles, the saving is smaller.
• Interface: that is a fair reason. Rank Math shows more settings, and AIOSEO sits between the two.
• Performance: be careful, for the reasons above.
• A missing feature: check the exact tier first. Redirects and schema are the usual triggers.

How to switch without breaking anything

Never run two SEO plugins at once. Both will output titles, descriptions, canonicals and schema, and the result is duplicated, conflicting markup.

1. Back up the database and files.
2. Run the new plugin's import tool.
3. Check titles, descriptions, canonicals and schema on your main pages.
4. Export redirects first, because they do not always travel with an import. The Rank Math redirect guide covers this.
5. Deactivate and delete the old plugin.
6. Submit the new sitemap in Search Console, since the URL may differ.
7. Watch indexing and impressions for two weeks.

Anobee moved one site from Yoast to Rank Math in June 2026. The import took about fifteen minutes, and five posts were checked before Yoast was deactivated. That is one migration, so treat it as a workflow record, not evidence about either plugin. The Rank Math setup guide covers the settings afterwards.

To settle all in one seo vs yoast, count your sites, check whether any belong to clients, and work out what you will pay in year two. Then go and fix something that is actually broken.
