Google Structured Data Markup Helper is a point-and-click Google tool that helps you create structured data markup for a web page or HTML email. You can enter a page URL or paste HTML, highlight details such as an event name, date, venue or product price, and generate sample markup for your site.

The tool supports two input routes, Website and Email. Its example event data includes the date October 15, 2026. Structured data gives Google clearer information about a page. When the implementation meets Google's requirements, the page may qualify for an enhanced search result called a rich result. It does not guarantee higher rankings or a rich result appearance.

How Does Google Structured Data Markup Helper Work?

Google Structured Data Markup Helper lets you tag visible information on a page and map each item to a Schema.org property.

  1. Open the tool and select Website or Email.
  2. Choose a data type, such as Event, Movie, Product or Article.
  3. Enter a publicly accessible URL or paste the page HTML.
  4. Select Start Tagging.
  5. Highlight relevant information on the page.
  6. Assign each item a property, such as name, startDate, location or price.
  7. Add any missing required information.
  8. Select Create HTML.
  9. Copy or download the generated code.
  10. Add the code to your site and test it with Google's Rich Results Test.

On an event page, for example, you might tag:

  • Event name
  • Start date
  • Venue
  • Address
  • Ticket price
  • Event image

The generated markup describes how those details relate to the event. Search engines can then process the information as structured data.

What Type of Code Does the Tool Generate?

Google Structured Data Markup Helper generates JSON-LD by default and also supports Microdata. Google recommends JSON-LD for most website implementations because it is usually easier to add and maintain without placing markup attributes throughout the visible HTML.

JSON-LD

JSON-LD usually sits inside a script block on the page:

<script type="application/ld+json">
{
  "@context": ""@type": "Event",
  "name": "Digital Marketing Conference",
  "startDate": "2026-10-15T09:00:00-04:00",
  "location": {
    "@type": "Place",
    "name": "New York Convention Center"
  }
}
</script>

Microdata

Microdata adds attributes directly to HTML elements. It works, but it can be harder to maintain because the structured data is mixed with the page's visible content.

Is Google Structured Data Markup Helper a Schema Markup Generator?

Yes. Google Structured Data Markup Helper creates markup that uses the Schema.org vocabulary. Schema.org includes types and properties for entities such as products, events, organizations, recipes and reviews.

Schema.org describes the vocabulary. Google's documentation determines which structured data features Google Search supports and which properties are required for eligibility. A Schema.org type may be valid without producing a Google search enhancement.

What Is the Difference Between Markup Helper and the Rich Results Test?

The tools have different jobs. Markup Helper creates sample markup, while the Rich Results Test checks whether Google can process markup for supported rich results.

Tool Primary function
Structured Data Markup Helper Creates sample markup by letting you tag page content
Rich Results Test Checks whether Google can process markup for supported rich results
Schema Markup Validator Checks Schema.org markup without Google-specific eligibility checks
Search Console reports Shows structured data issues on pages Google has crawled

Use the Rich Results Test when you want to check eligibility for a Google search feature. Use the Schema Markup Validator for broader Schema.org checks.

Does the Tool Automatically Add Structured Data to a Website?

No. Google Structured Data Markup Helper creates example code, but you still need to:

  • Review the generated markup.
  • Add or correct properties.
  • Place the code on your website.
  • Test the implementation.
  • Publish the changes.
  • Monitor the page in Google Search Console.

Google explains that the generated file may need changes before you add it to a site.

If you use WordPress, Shopify, Wix or another content management system, the platform may already create structured data through its settings or an SEO plugin. Check the page source before adding another system. Two implementations can create duplicate or conflicting markup.

What Are the Limitations of Google Structured Data Markup Helper?

Google Structured Data Markup Helper is useful for basic pages, but it is not a complete structured data implementation. It:

  • Does not deploy code to your website.
  • May not support every Schema.org type or property.
  • Produces a starting point that may need manual editing.
  • Does not replace Google's structured data guidelines.
  • Cannot make hidden or inaccurate information eligible for rich results.
  • Does not guarantee rankings, traffic or a rich result.
  • May not handle complex relationships or advanced schema correctly.

Google requires structured data to match information that users can see on the page. Hidden, misleading or inaccurate markup can make the implementation ineligible for search enhancements.

Should You Use Google Structured Data Markup Helper?

Use Google Structured Data Markup Helper if you are new to structured data or need markup for a small number of straightforward pages. It is also useful for learning how visible page details map to Schema.org properties.

For a large website, ecommerce catalogue or complex publishing system, structured data managed through a CMS, template or development workflow is usually easier to maintain. The process is:

  1. Identify the Google-supported structured data type.
  2. Generate or write the markup.
  3. Confirm that the marked-up information is visible on the page.
  4. Test it with the Rich Results Test.
  5. Publish the markup.
  6. Check Search Console after Google crawls the page.

Markup Helper creates structured data code. It does not complete the technical SEO work around that code. You still need to review, test and maintain the final implementation.
