Structured Data & Schema Markup: The Cornerstones of Technical SEO

Updated: Aug 11, 2026

Structured data, also known as schema markup, is the next stage in our long (and quite literally endless) series on SEO.

First things first—SEO can be split into four types, and structured data falls under the umbrella of technical SEO. As part of a website's technical SEO strategy, structured data provides search engines with explicit clues about the meaning and context of your content, helping them better understand what's on the page.

Of course, as with anything SEO, there's a bit more to it. Let's get into it!

What is Structured Data?

With computers becoming so impressively user-friendly, it's easy to forget that they don't function like we do—we don't speak the same language.

Structured data prevents your web pages from looking like alphabet soup from the search engine's perspective. It's a method of organizing website content to provide Google with clear information about each element on a page. 

By tagging content with specific data types, structured data gives search engines additional context to help them identify and categorize information on a page. When supported by Google, it can also make eligible content available for richer appearances in search results.

The Scoop on Schema Markup

Schema markup is the code used to implement structured data on your website, commonly using Schema.org vocabulary.

It acts as the language that communicates directly with search engines, explaining what each part of your content represents. 

Schema markup helps define various elements on your page—whether it's a product, video, or article—making it easier for search engines to understand and classify your content. When supported by Google, structured data can also make a page eligible for rich results that provide searchers with additional information directly in the search results.

Basically, schema markup tells a search engine, “Hey, this is a product!” or “Hey, this one’s a blog!” A product schema would contain information like the product name, price, and availability, while an article schema can contain information about the author, headline, publication date, and images.

Best Practices for the Best Websites

While simple in theory, structured data and schema markup can be challenging to navigate the first time around.

To effectively implement structured data on your website, begin by selecting the appropriate schema markup that corresponds with the specific content you want to emphasize – Google’s Structured Data Markup Helper is your best friend in this stage (well, aside from The Brand Brew ®, of course).

Once your schema is in place, test it to make sure it's working as intended. Google's Rich Results Test can identify which Google rich results a page may be eligible for, while the Schema Markup Validator can be used to validate broader Schema.org markup. Keep your structured data accurate, relevant to the visible content on the page, and aligned with current guidelines.

Why Bother with Structured Data?

As we know, it helps search engines understand what’s going on in your web pages. But why does that matter?

1. Enhanced Search Engine Understanding

Structured data helps search engines better understand your content (which you can monitor and optimize using Google Search Console). 

By providing clear, explicit information about the content on a page, structured data can help search engines interpret and classify it more accurately. It gives them additional context about what they're looking at and how different pieces of information relate to one another.

Here’s some food for thought:

• When Rotten Tomatoes added structured data to 100,000 unique pages, it observed a 25% higher click-through rate for pages enhanced with structured data than those without.

• The Food Network has converted 80% of its pages to enable search features and has seen a 35% increase in visits.

• Nestlé has measured that pages that appear as rich results in search have an 82% higher click-through rate than non-rich result pages.

2. Improved SERP Features

Search Engine Results Pages (SERPs) are no longer just a list of websites to choose from. Now they include a whole range of special search result features and enhancements, from the local business map pack to the sitelinks and even image metadata, that further increase your chances of earning clicks from interested buyers.

Needless to say, you want these features.

Structured data can make eligible content available for certain rich results in Google Search, giving searchers additional context before they click. Depending on the content and markup type, these enhanced results can include information such as article details, product information, ratings, events, recipes, breadcrumbs, and more.

Not every type of structured data produces a visible search enhancement, and valid markup doesn't guarantee that Google will display a rich result. Think of schema as helping search engines better understand your content and making eligible pages available for supported search experiences.

3. Staying Ahead of the SEO Curve

SEO is never static, and search engines are constantly updating their algorithms to prioritize user experience. 

Search engines continue to evolve how they interpret information and present it in search. At the same time, supported search features change, which makes it important to keep your structured data accurate and aligned with current guidelines.

Used alongside strong content, internal linking, technical SEO, and a clear search strategy, structured data becomes another ingredient in helping search engines understand your website and the information it provides.
