What Is Schema Markup?

A few years back, I traveled to Cancun, Mexico. I remember going to one of the popular markets and attempting to buy a beautiful sombrero. Unfortunately, a transaction that should have taken a couple of minutes took more than 30 minutes of my time.

The problem?

The seller and I couldn't understand each other.

Finally, one of the other vendors came and helped interpret. We laughed at the simple misunderstanding, and I happily walked away with my new hat.

What does this have to do with schema markup?

Schema markup is like that vendor who helped us understand each other—it bridges the gap between human and machine language.

Without schema markup, search engines can scan the words on your page, much like the vendor heard my broken Spanish. But they might miss the meaning and context of your content. For example, if you run a food blog, they might see words related to “recipes” but not understand it's a specific “vegan chocolate cake recipe with a five-star rating.”

This lack of clear understanding can lead to your content not being displayed in the most relevant search results or rich snippets. Just like I almost left without my hat due to the communication barrier, your target audience may miss out on your valuable content.

So, what is schema markup?

Schema markup, or [structured data](/content/what-is-structured-data-and-how-does-it-impact-seo/ "What is Structured Data and How Does it Impact SEO?"/index.html), is a semantic language that helps search engines better understand your content. It uses a tag system where tags, or labels, are added to website code to help search engines understand the page better.

Types of Schema Markup

Different types of schema can be applied to web pages. You’ll choose a schema related to your page content.

Google recognizes over 3 dozen [schema types](/content/types-of-schema-markup/ "21+ Types of Schema Markup You Need to Know in 2025"/index.html), including the following:

All In One SEO (AIOSEO) has 19+ preset schema types you can easily add to your content. It also makes it super easy to add custom schema markup, even if you don't have any coding knowledge.

How Does Schema Markup Impact SEO?

Because schema markup helps search engines understand your pages better, those pages may rank for additional keywords.

Schema Markup Creates Rich Snippets

Additionally, when schema markup is added to a page, that page becomes eligible for display as a rich snippet in search results.

Some rich snippets, like those created by [schema for **products**](/content/product-schema-markup/ "How to Use Product Schema to Boost Your SEO and Drive Sales"/index.html), are visually prominent.

To see the difference, compare this standard snippet . . .

. . . with this rich snippet.

The rich snippet has more images and information (under the description) on free deliveries and returns, courtesy of schema markup.

Some rich snippets, like the ones below, look like ads.

The images above are interactive: as you hover your cursor over them, up to 5 images display consecutively.

And this rich snippet below displays local shipping and tax information.

Not surprisingly, research shows that rich snippets attract more click-throughs from search results pages.

Is Schema Markup a Ranking Factor?

To be clear, schema markup is not a ranking factor. In other words, you can’t simply add schema markup to a poor quality page and see it climb the rankings.

Quality content will always be the most important [ranking factor](/content/google-ranking-factors/ "10 Google Ranking Factors to Act on in 2025"/index.html).

However, as mentioned, schema markup will help Google understand your page and rank it for relevant keywords.

Now, let’s pay more attention to your web pages by adding schema markup.

How to Add Schema Markup to WordPress Web Pages

Ready to add schema markup to your site?

Despite it being code, I'll show you a no-code way.

Step 1: Download and Install All In One SEO (AIOSEO)

The easiest way for WordPress users to add schema markup is to use an SEO plugin.

I recommend [All in One SEO](/content/ "All in One SEO - WordPress SEO Plugin and Toolkit"/index.html) (AIOSEO), a beginner-friendly plugin used by bloggers and small businesses.

All in One SEO is an established SEO plugin with over 3 million users and thousands of 5-star reviews on WordPress.org.

After you [download and install](/content/docs/installing-all-in-one-seo-pro/ "Installing All in One SEO Pro"/index.html) the plugin, a wizard will walk you through a few setup steps.

Now, you’re ready to add schema markup.

Step 2: Choose a Schema Type

While you’re logged into WordPress, navigate to a page that you want to add schema markup to.

Click the AIOSEO button at the upper right to open the AIOSEO sidebar.

Then click Schema.

You’ll see there’s already some “ Schema in Use.” AIOSEO automatically adds article schema to blog posts.

Now, click the blue Generate Schema button.

The Schema Catalog is now visible.

Here, you can choose between 19+ different types of schema.

Find the type you want to add and click the plus (+) icon next to it.

For our example, we’ll choose Event schema.

Step 3: Fill Out the Form

Next, a pop-up window will open with some form fields to fill out. (Each schema type has different form fields.)

Fill in the information about the event, including organizer, dates, location, and how to get tickets. Skip any items that aren’t relevant to your page.

When you’re done, click the Add Schema button at the bottom of the popup window.

Step 4: Editing or Deleting Your Schema

Once you've added your schema markup, editing or deleting it is super easy. Just follow these steps:

Boosting Your E-E-A-T Using Author Schema

In addition to the 19+ types of schema AIOSEO offers, it also has a special author SEO feature that adds an author's related information to your page.

This [Author SEO](/content/features/author-seo-google-e-e-a-t/ "Author SEO"/index.html) feature makes it easy to communicate your authors’ expertise and experience.

Google has long emphasized the [importance of E-E-A-T](/content/what-is-google-eat/ "What is Google E-E-A-T? Understanding Google’s Secret Sauce for Creating Effective Content"/index.html) (Experience, Expertise, Authority, Trustworthiness). So, it’s a good idea not to assume your readers or Google knows about your authors’ experience.

To use Author SEO, you simply fill in some author information, and here’s what you get …

An author box that appears at the bottom of each author’s page. This provides space for a short bio, photo, social links, and areas of experience or expertise.

A hyperlinked byline that links to a page listing all of that author’s articles plus a detailed bio including education and employer, if desired.

The option for a second byline for a fact-checker or reviewer (editor).

AIOSEO also automatically adds [author schema markup](/content/seo-glossary/author-schema-markup/ "Author Schema Markup"/index.html) to your page.

Like schema markup, this author SEO feature doesn’t automatically translate to rankings. But it can help you communicate the experience and expertise of your content creators, which can indirectly influence search rankings.
