# Schema Markup Validator review (2026): is it any good? > Free schema.org checker for any structured data on a page or snippet Checked Oct 23, 2026 ยท graded Oct 23, 2026 by ToolGPA. The Schema Markup Validator is a free tool from the schema.org project that checks the structured data embedded in a web page, or in a pasted code snippet, against the schema.org vocabulary. It replaced Google's old Structured Data Testing Tool, which moved to the schema.org community by April 2021, and it validates all schema.org types without checking for Google's rich results. - **Category:** Technical SEO & Site Audits - **Made by:** Schema.org - **Website:** https://validator.schema.org - **Runs on:** Web - **Who should skip it:** Skip it if you want to know about Google rich results, which need Google's Rich Results Test. - **Facts last checked:** Oct 23, 2026 ## Pricing As of Oct 23, 2026, Schema Markup Validator is free to use. - **Pricing model:** Free - **Free plan:** Open to anyone in a browser with no account: fetch a URL or paste a code snippet and run the test. - **Free trial:** None listed. | Plan | Price | What you get | | --- | --- | --- | | Free | $0 | Validates schema.org markup from a fetched URL or a pasted code snippet, with the interface in several languages. | Read from https://validator.schema.org on Oct 23, 2026. Prices change, so confirm with Schema Markup Validator before buying. ## Key features - **Fetch a URL:** Enter a page address and the validator fetches the page and checks the structured data embedded in it. - **Test a code snippet:** Paste markup into the editor to check it before it is published, and rerun the test after each change. - **Any schema.org type:** Checks syntax and compliance with schema.org standards for every type in the vocabulary, not only the ones Google uses for rich results. - **No Google-specific warnings:** Google describes it as validating schema.org data without Google feature-specific warnings, which its Rich Results Test covers instead. - **Interface in many languages:** The validator's interface can be switched between dozens of languages, including Japanese, German, Hindi, Arabic and Spanish. ## Good for - Developers checking that schema.org markup is well formed - Sites using structured data for engines and apps other than Google - Anyone who used Google's retired Structured Data Testing Tool ## Worth knowing - Does not tell you whether a page qualifies for Google rich results; Google's Rich Results Test does that. - Tests one URL or one snippet per run; the page offers no site crawl, scheduling or saved history. - Hosted by the schema.org project, a community effort founded by Google, Microsoft, Yahoo and Yandex, not a company selling support. ## ToolGPA grades **GPA: 2.8 out of 4**, graded Oct 23, 2026. The Schema Markup Validator checks the structured data on a page or in a pasted snippet against every schema.org type, for free and with no account. But it won't tell you whether a page qualifies for Google rich results, it tests one URL or snippet per run with no crawl or saved history, and a community project runs it, not a company offering support. - **Value for money: A.** Free, from the schema.org project, with URL fetches and snippet tests. Nothing to buy. - **Free plan and trial: A.** Open to anyone in a browser with no account and no limits on record. - **Features: D.** One narrow job: checking syntax and schema.org compliance for any type, from a URL or a snippet. No rich result checks, no site crawl, no scheduling and no saved history. - **Ease of use: B.** No rating on record, and nothing to set up: enter a URL or paste code and run the test. The interface switches between dozens of languages. - **Platforms and integrations: C.** Web only, with no API or integrations on record. These are ToolGPA's own grades.
