What is Schema and what is structured data used for (2025)

Have you ever wondered how Google displays such accurate information in search results, such as reviews, schedules, or prices? The answer lies in Schema and structured data.

In this article, we will clearly explain what Schema Markup is, why it is key for your website, and how you can use it to stand out on the Internet. You will also learn how to create it with AI for your local business. Let’s get started!

What is Schema?

Schema is a standard language created by Google, Microsoft, Yahoo, and Yandex to organize information on web pages. Through Schema Markup, sites add structured data, which are tags in the HTML code that explain what each element means (a name, a date, a price, etc.).

This helps search engines better understand your content.

Think of it as a guide for Google: without Schema, your website is like a book without an index; with Schema, it’s a book with clear, easy-to-find chapters.

According to Google, websites with structured data are more likely to appear in rich results, such as rich snippets.

What is structured data?

Structured data is the format Schema uses to describe the content of a page.

For example, if you have a recipe, structured data indicates the title, ingredients, cooking time, etc.

This format follows a universal standard that is documented in Schema.org, a database with hundreds of types of markup, from events to products or reviews.

Structured data does not change how your site looks to users, but it does change how search engines and AI interpret it. This is key to improving your visibility on Google and helping assistants such as Siri or Grok better understand your content.

What is structured data used for?

Implementing Schema markup has concrete benefits for your business or project.

  • Improves SEO: Structured data helps Google classify your content, increasing the chances of appearing in featured snippets or rich results.
  • Increases CTR (click-through rate): Results with stars, images, or additional information are more attractive. A study bySearch Engine Land found that rich snippets can increase CTR by up to 30%.
  • Facilitate AI comprehension: Language models such as Grok or ChatGPT depend on clear data. Schema allows them to interpret your content accurately, which can improve their recommendations in AI-generated responses.
  • Make your site more accessible: Structured data benefits users with disabilities by improving compatibility with screen readers.

Most common Schema types

Schema.org offers hundreds of markup types. Some of the most commonly used are:

  • Article: For blogs or news, it describes the title, author, and publication date.
  • Product: Ideal for e-commerce, it includes price, availability, and reviews.
  • LocalBusiness: Perfect for brick-and-mortar businesses, with data such as address, hours, and phone number.
  • Recipe: For recipes, it details ingredients, preparation time, and calories.
  • Event: For events, it includes date, location, and ticket prices.

For example, a bakery’s website could use LocalBusiness markup to display its hours on Google Maps and Recipe to highlight a homemade bread recipe in search results.

How to implement structured data

Adding Schema markup is not as complicated as it seems. Here are the basic steps:

  1. Choose the type of Schema: Visit Schema.org and select the markup that best suits your content.
  2. Generate the code: Use tools such as Google’s Data Markup Generator or JSON-LD Generator to create the code in JSON-LD format (the most recommended by Google).

Insert the code into your website: Paste it into the <head> or <body> of your HTML page. If you use WordPress, plugins like Yoast SEO or Rank Math simplify this process.

Test the result: Use Google’s Structured Data Testing Tool to verify that everything is correct.

Many sites only use basic Schema, but you can stand out by adding less common properties.

For example, in a Product markup, include the brand or aggregateRating field to show more details in the results. This not only improves your SEO, but also makes your content more useful for AI looking for specific data.

How to create a Schema with AI for a business

Artificial intelligences, such as Grok or ChatGPT, can help you create a custom Schemamarkup for your business. If you use a clear prompt, you can get JSON-LD code ready to use.

Here’s how to do it and an example of an effective prompt.

Steps to use AI to create Schema

  1. Define your business data: Gather key information such as name, address, phone number, hours, business type (e.g., restaurant, store), and site URL.
  2. Create a clear prompt: Tell the AI the type of Schema (e.g., LocalBusiness) and the specific details you want to include.
  3. Validate the generated code: Use Google’s Structured Data Testing Tool to make sure the code is correct.
  4. Implement the code: Add it to your site manually or with a WordPress plugin such as Yoast SEO.
  5. That’s it! Simple and fast. You can validate the Schema to see how it turned out on Schema.org or with Google.

Example of a prompt for AI

Here is an example of a prompt you can use with AI to generate a Schema for a local business.

Prompt:

Generate JSON-LD code for a LocalBusiness Schema markup for a bakery called ‘Dulce Hogar’. Include the following details: address ‘123 Main Street, City, Country,’ phone number ‘+123456789,’ hours Monday through Friday from 8:00 a.m. to 6:00 p.m., website ‘https://d Karla,’ business type ‘Bakery,’ and average rating of 4.5 stars. Make sure the code is valid according to Schema.org and optimized for SEO.

How to add Schema markup in WordPress

If your website is on WordPress, implementing structured data is even easier. As mentioned above, plugins such as Yoast SEO, Rank Math, or Schema Pro allow you to add Schema without touching any code.

For example:

Yoast SEO: Automatically configures Organization or Article markup for your site.

  • Rank Math: Offers templates for Product, Recipe, and more, with previews of how it will look on Google.

Additionally, if you use a Schema-compatible theme, such as GeneratePress, the markup is integrated natively. Just be sure to validate the code with Google’s tool to avoid errors.

The cooking blog “Tasty” uses Schema Recipe to display its recipes in rich snippets. When you search for “chocolate cake recipe” on Google, its results include images, cooking times, and ratings, all thanks to structured data.

Benefits of Schema that no one knows about

In addition to SEO, there are advantages that few mention:

  • Prepare your website for the future: With the rise of voice search and AI, structured data will become even more crucial. Google and assistants like Grok prioritize sites with clear information.
  • Compete with large sites: Even if your website is new, Schema gives you an advantage to appear in rich results, leveling the playing field.
  • Improve analytics: Some structured data, such as event data, allows Google Analytics to track more specific interactions.

Common mistakes when implementing Schema

Avoid these mistakes to maximize the benefits:

  1. Using incorrect Schema: Don’t mark an article as Recipe or a product as Event. This confuses Google.
  2. Poorly implemented code: Errors in JSON-LD can cause Google to ignore your markup. Always validate with Google’s tool.
  3. Excessive markup: Don’t abuse Schema to inflate your SEO. Google penalizes “structured data spam.”
