Rank Math: what is in the free version, how the schema builder works, and an honest comparison with Yoast

Rank Math is a WordPress SEO plugin built around modules you switch on and off. Its free version is unusually complete: titles and descriptions with templates, canonical control, robots directives per content type, an XML sitemap, several focus keywords per post, a redirection manager, a 404 monitor, a schema generator with a wide library of types, Search Console data in the dashboard, and local business and WooCommerce modules. The 100 point score next to your draft is a checklist of on page conventions, not a measurement of anything Google does. The current free and paid feature split and the prices are published on Rank Math's own pages, so read those rather than any third party summary.

This page covers what Rank Math does, how its schema tools work, and how it compares with Yoast. For the wider WordPress setup, permalinks, hosting and archive sprawl, see a general WordPress SEO guide.

The modular design, and why it matters

Rank Math ships as a set of modules in its dashboard: sitemap, redirections, 404 monitor, schema, local SEO, image SEO, link counter, role manager, analytics and more. You turn on what you use and leave the rest off, which keeps both the admin and the loaded code smaller than a plugin that does everything all the time.

Practical advice on a new install: turn on sitemap, schema, redirections and the 404 monitor. Leave the rest off until you have a reason. Revisit the module list every few months, because the list grows between releases.

How the schema tools work

This is the area people come to Rank Math for, so it is worth being precise about the parts.

• Default schema per post type. In the settings for each content type you choose what it is: Article, Product, Service, and so on. Every new item then ships with that markup instead of nothing.
• The schema generator on the post itself. A library of types you can add, edit and preview per page, with fields populated from your post data through variables.
• Custom schema. You can write or paste JSON-LD directly, which is the escape hatch for a type the library does not cover.
• Schema Templates, which apply a configured schema automatically across a whole post type or a filtered set, are part of the paid version. Rank Math documents the feature and its tier on its own knowledge base page, and the general schema setup is covered in its schema markup guide.

Whichever route you use, validate the output on a published URL with Google's Rich Results Test, and check the type is actually eligible for a rich result in Google's search gallery before spending an afternoon on it. Marking up something the page does not visibly contain is the one mistake to avoid here.

Rank Math and Yoast, side by side

Area	Rank Math	Yoast SEO
Titles, descriptions, canonicals, robots, sitemap	Free	Free
Focus keywords per post	Several in the free version	One in the free version, several in Premium
Redirects and 404 monitoring	Free module	Premium
Structured data	Wide type library and custom JSON-LD, with bulk templates in the paid tier	A connected graph generated automatically, strong on correctness, fewer types to pick from
Content analysis	A 100 point checklist per post, dense and detailed	Traffic light SEO and readability analysis, more editorial in tone
Admin experience	More switches, more modules, steeper first hour	Fewer decisions, gentler for a non specialist
Documentation and ecosystem	Good and growing	The widest, and the one most freelancers already know
Where to check pricing	rankmath.com pricing and its free versus paid comparison	yoast.com pricing

The honest summary: pick Rank Math if you want redirects, several keyphrases and a broad schema library without paying, and you do not mind a denser interface. Pick Yoast if you are handing the site to a writer or a client, or if your priority is a clean, automatically correct schema graph and documentation everyone has read. Both cover the full technical surface, and neither one is the reason a site ranks or does not.

Reading the 100 point score honestly

The score counts whether your draft follows a list of on page conventions: the keyword in the title, the slug, the first paragraph and a subheading, a meta description written, enough words, an internal link, an external link, an image with alt text. Rank Math explains the individual tests in its own documentation.

Use it as a pre publish checklist and act on the structural items. Ignore the pressure to reach 100 on every post, because the last few points usually mean adding a keyword somewhere a human would not have put it. Google's standard is set out in its guidance on helpful, reliable, people first content, and a page that reads naturally and answers the question beats a page scoring 100 that does not.

Switching plugins without breaking the site

• Install the new plugin, run its importer, and import settings, titles and descriptions, and redirects from the old one. Rank Math documents its import and export process.
• Deactivate and delete the old plugin. Do not leave both active. Two plugins emit two title tags and two canonicals.
• View source on your homepage and one blog post and search for rel="canonical". One is correct, two is the bug you just introduced.
• Check your sitemap URL, because it changes between plugins, and resubmit it in Search Console.
• Spot check ten pages for titles and descriptions that did not carry across, then crawl the site and sort by title to catch the rest.

Asked and answered: Rank Math

Is Rank Math better than Yoast?

They are different trades rather than different quality. Rank Math gives more away in its free tier, particularly redirects and multiple keyphrases. Yoast gives a simpler interface, a very solid automatic schema graph, and the familiarity that matters when other people will edit the site. Both do the job.

Is the free version of Rank Math enough?

For most sites, yes. Titles, descriptions, canonicals, robots directives, sitemaps, schema, redirects and 404 monitoring are all there. The paid tier is about automation at scale, bulk schema templates and extra analytics.

How much does Rank Math cost?

Check its pricing page, since the tiers and currencies change. The useful question is which features you need, and the free versus paid comparison answers that directly.

Do I need a 100 out of 100 score on every post?

No. Fix the structural tests, which are the title, the slug, the first paragraph, a subheading, the description, and one internal and one external link. Leave the rest when the natural sentence is better.

Can I run Rank Math and Yoast together?

Run one. Two plugins produce duplicate meta tags, duplicate canonicals and two sets of structured data. Import into the one you are keeping and delete the other.

Does adding schema with Rank Math get me a rich result?

Valid markup makes a page eligible for the rich result types Google supports, and Google then chooses when to show one. Mark up what is genuinely on the page, validate it, and check the type in the search gallery first.

Not a field in the plugin

Rank Math, like Yoast, lets you set titles, descriptions, schema and a score. It does not set what an assistant says. The reply comes from many pages on the web, and your plugin settings are one input to it.

So the check lives outside WordPress. Pick the question each important page should answer, ask it in ChatGPT, Gemini and Perplexity, and read whom they name. If your page is missing, the cited sources show what stood in its place. AI Knows Us automates the check and keeps the history.
