No Bad Questions About SEO
Definition of Structured data
What is structured data in SEO?
Structured data in SEO is a standardized way of labeling information on a webpage, so search engines can better understand its content. It uses code (often in the form of Schema.org markup) to highlight specific details such as product information, reviews, events, recipes, or FAQs.
What is the difference between structured and unstructured data?
Structured data is organized and easy for machines to read. It lives in predefined formats such as databases or spreadsheets, where information is stored in rows and columns. In SEO, structured data usually refers to Schema.org markup. This code helps search engines understand your content and display it in rich snippets such as star ratings, product details, or event dates. These snippets make your pages stand out in search results and often increase click-through rates.
Unstructured data has no fixed format and is harder for machines to process. It includes text, images, audio, and video, for example, blog posts, customer reviews, emails, or social media content. While unstructured data contains valuable insights, it requires additional processing with methods like AI or NLP to become searchable and useful.
In short, structured data is clean, predefined, and machine-friendly, and in SEO, it directly improves visibility in search results. Unstructured data is free-form, harder to interpret, but rich in context that can reveal important insights.
