What is Structured Data for SEO?

Structured data, aka schema markup, is a way of organizing data that helps search engines better understand and categorize your website content.

The site contains a standard list of markups that all search engines support.

Here is an example of the schema used to structure the unstructured web page data:

What is Unstructured Data?

Unstructured data is an undefined piece of information that has no standard format.

Most of the data produced every day is unstructured. Companies collect so much info, but if unstructured information is hard to analyze, then what good is it?

The good part is that we are getting better at handling unstructured data such as pictures, audio, and text that has not been organized in a specific manner.

But it is still challenging and requires machine learning and natural language processing technologies to extract insights from this data.

Search engines like Google have been attempting to comprehend unstructured data for a long time, sending bots to crawl websites and understand their content. They are constantly improving at this, but unstructured data is still hard to comprehend.

Examples of unstructured data:

  • Text documents, including PDFs, chats, and presentations

There are many instances where we produce unstructured data. When you take a picture, send an email, or create a voice note, for example.

However, when it comes to SEO, you must always keep structure in mind because without it, Google might have a difficult time figuring out what your webpage is about.

Even when you don’t use structured data, use semi-structured data in the form of meta descriptions, headers, H1s, and H2s.

What is Semi-Structured Data?

Semi-structured data is a blend of structured and unstructured data.

Rather than relying on a rigid structure like structured data, this form of data uses tags, attributes, and metadata to quickly communicate information to search engines.

As stated previously, unstructured data is what we create on the web most of the time.

However, when we combine this unstructured data with an approach to organize or locate it — such as metadata on web pages or links — we get semi-structured data.

Examples of semi-structured data are:

  • Images with metadata like alt text and a date

Pro Tip: Use on-page optimization tools like Surfer SEO and Yoast to ease the content structuring process.

What is and How Can it Help Structure Data for SEO?

Structured data, in the broadest sense, refers to a format of storing data in an organized manner. However, in the context of SEO, structured data refers to one thing: markup.

It’s worth noting that isn’t the only SEO-fluent markup vocabulary. There are websites like that facilitate markup for specific data sets. Still, is the most trusted and popular one.

What is

An initiative to build a better semantic web, is a community founded by Google, Microsoft, Yahoo, and Yandex. The four search engines collaborated to develop schema vocabularies for structured data markup across the internet.

Marketers and website developers can easily participate in this initiative thanks to a common vocabulary consisting of types and properties.

Formats Supported by

JSON-LD, Microdata, and RDFa are the most commonly used structured data markup languages and all are available on

Let’s get a quick look at the top three structured data markup languages for SEO:

  • JSON-LD — Because it’s lightweight and simple to add, JSON-LD can be inserted into the header of your website without disrupting anything. Google also prefers this format.

Pro Tip: Use JSON-LD data format, as it’s preferred by most search engines.

What is Structured Data Used for in the Context of SEO?

Here are some of the common use cases of structured data for SEO.

Knowledge Panel

When you search for a person, place, or company on Google, you will come across a knowledge graph or knowledge panel — a comprehensive summary of data sourced from reputable sources.

Having Google create a knowledge panel for your brand is out of your control. However, once they do, you can control the data they share by connecting them to structured data on your site.

You can click on “suggest an edit” to instruct Google on what information you want to be displayed on the panel.

Rich Snippets

Google provides rich results that go beyond the standard blue link. A carousel, an image, or other non-textual elements can be included as part of a rich result.

Here’s an example of rich snippets on Google SERP. See how they stand out.

Do not confuse rich snippets with featured snippets. Both are different in context and SERP placement.

There can only be one featured snippet for a search query and that too when Google considers your content so valuable that it displays it at the top of the search results, like this:

Google determines the most valuable content to display for featured snippets without the use of structured data.

Rich Cards

Structured markup is used in rich cards to display SERP content in a more engaging and visual format. The focus is on delivering a better mobile user experience than rich snippets.

Just like rich snippets, rich cards are built on They appear like this on the SERP:

For instance, if you have a recipe site, you can create a visual representation of each dish on the site to build a richer preview. Users who are searching for a recipe will be able to find it right away, thanks to this visual format.

However, we recommend using both rich cards and snippets to give users a comprehensive web browsing experience.

Interactive Search Results

Google Search also supports a more interactive and enhanced type of rich result known as enriched search results.

A very common example of an interactive search result featuring an immersive pop-up experience or other advanced interaction technology is the results for ‘jobs in an area.’

Google uses structured data to create an advanced filter feature that includes thousands of websites.

If you want your job result to appear in this location, you must include the appropriate markup and ensure it is as comprehensive as possible. This also applies ro results for recipes, events, etc.

AMP (Accelerated Mobile Pages)

An Accelerated Mobile Page (AMP) is a lightning-fast and mobile-oriented version of your web page that can be substituted for the original page in mobile search results.

Image via Google

Google Search can show AMP pages as rich results, just like other web pages. To help Google comprehend your web page better, you need to add structured data to it.

However, Google does not guarantee that using structured data will result in a favorable outcome in search results. For more info, see Google’s Structured Data General Guidelines.

Structured vs. Unstructured Data: A Comparison

Structured data is predefined and can be arranged in a spreadsheet like a date, name, address, barcode, and other similar data.

Unstructured data, on the other hand, refers to raw information captured in its initial form (like text files, photos, audio files, etc.)

Here is a quick comparison of structured vs. unstructured data:
