Microdata

Quick Definition

Microdata is an older format for adding structured data inline in HTML using itemprop and itemscope attributes.

In context

Microdata still works but JSON-LD is now Google's preferred format. New sites should default to JSON-LD; existing Microdata implementations don't need to be migrated unless they're causing maintenance problems.
