Structured Data Markup

Structured data — also known as schema markup — is a machine-to-machine learning language that allows search engine spiders (Search Bots) to contextualize and understand each page's content so that they can accurately index your web pages in search results and amplify them as rich features — like frequently asked questions, ratings, and reviews — which are embedded alongside standard blue links. This page provides a basic introduction to the concept, covers why it is important, and looks at the different options you have to implement it on your website.

To learn more about different types of structured data markup, and to see examples, read Examples of Structured Data.

Search engines experience website content differently than humans. For search engines, every unique URL is a separate page. And if a single page on your website is accessible by multiple URLs with similar or near similar content, Google interprets them as duplicate versions of the same page. Consequently, Google will choose one URL as the original and most important piece of content and index that. Sometimes, they make a mistake and choose the wrong one. This makes it important to take the proactive step of telling Google which one is which. Continue reading to learn more.
