What is structured data?
According to Google’s Introduction to Structured Data, “When information is highly structured and predictable, search engines can more easily organize and display it in creative ways.”
A good way to think about structured data is to understand that unstructured data, with which we likely are more familiar, is more free form in nature. Examples of unstructured data are our text files and photos, video and audio files. They’re our blogs and social media posts.
