Do you have to pay for schema markup tools?

Published September 28, 2026 · Editor: Kaz (pen name)

If you're on WordPress, you may already own a schema tool

Yoast SEO Premium costs $118.80 a year, excluding VAT, for one site or domain. It generates structured data automatically and combines it into a single graph. Yoast's product page doesn't state a renewal price.

SEOPress PRO is $49 a year for one site, $59 for five and $149 for unlimited sites, excluding tax. Every PRO plan includes automatic and manual schemas, which the free version lacks, and SEOPress says you renew at the price you paid.

AIOSEO includes its Schema Generator on every plan. Basic, for one site, is $49.50 for the first year and renews at $99. Local business schema starts at the Plus plan.

Over three years on one site, that's $147 for SEOPress PRO ($49 × 3) and $247.50 for AIOSEO Basic ($49.50 + $99 + $99). Yoast can't be totaled the same way because its renewal price isn't published. Each price also buys redirects and other SEO features, which is why the SEO tools for WordPress guide looks at the whole plugin bill.

The two free validators test different things

Google's Rich Results Test loads a public page as Google's crawler and reports which rich result types its structured data can produce, along with errors and suggestions. It reads JSON-LD, RDFa and Microdata, but it only checks types Google supports, such as articles, breadcrumbs, events, local businesses, product snippets, recipes and reviews. A page blocked by robots.txt or noindex can't be tested.

The Schema.org Markup Validator grew out of Google's old Structured Data Testing Tool and is run by Google for the Schema.org community. It extracts JSON-LD, RDFa and Microdata, shows the resulting data graph and flags syntax mistakes. It is focused on Schema.org vocabulary alone. Google recommends JSON-LD where your setup allows it.

Valid markup that never shows up

Google says it "does not guarantee that your structured data will show up in search results, even if your page is marked up correctly according to the Rich Results Test." Its policies also rule out marking up content readers can't see, fake reviews or content unrelated to the page. Breaking them can bring a manual action, which removes the page's eligibility for rich results but, Google says, doesn't affect how it ranks in web search.

FAQ markup no longer earns anything visible in Google. Google stopped showing FAQ rich results on May 7, 2026, and removed the documentation on June 15.
