What is Structured Data?

Updated 14 Mar, 2018

Structured data refers to kinds of data with a high level of organization, such as information in a relational database. When information is highly structured and predictable, search engines can more easily organize and display it in creative ways. Structured data markup is a text-based organization of data that is included in a file and served from the web. It typically uses the schema.org vocabulary—an open community effort to promote standard structured data in a variety of online applications. Structured data markup is most easily represented in JSON-LD format, which stands for JavaScript Object Notation for Linked Data.

Does Structured Data help with SEO?

Absolutely! There is no question that structured data that produces rich snippet "bling" that improves SERP click through rates (CTR). Virtually every search engine expert on the planet will tell you that organic click through rates are a major search engine optimization ranking factor. Thus, structured data has a very high correlation with search engine rankings.


We use JSON-LD for many reasons. First of all, the markup is placed inside a script tag in the head of the HTML page ensuring no impact in the design of your site. Also, Google can read JSON-LD data when it is dynamically injected into the page's contents, such as by JavaScript code or embedded widgets in your content management system. JSON-LD is the recommended format and Google is in the process of adding JSON-LD support for all markup-powered features.

Does Structured Data work on mobile?

Yes, it works everywhere. Mobile implementation of Schema.org data is in its infancy. If you implement structured data correctly, you can also be eligible for a new sort of presentation in the form of mobile Rich Cards.
