Quick Answer
Microdata is a way to embed hidden metadata directly into your HTML so search engines and apps can understand what your content means—like who wrote it, when it was published, or what type of item it describes. You use HTML attributes like itemscope, itemtype, and itemprop to mark up your content with this extra information.
Key Takeaways
- Start simple—add just headline and author before expanding
- Always test changes with Google’s Rich Results Test tool
- Use schema.org URIs exactly as written—no typos allowed
- Boosting SEO by enabling rich snippets in Google search results
- Improving voice assistant responses by clarifying content meaning
What Microdata (HTML) means in practice
Think of Microdata as invisible labels you attach to parts of your webpage—like tagging a photo with 'author: Jane Doe' or 'date: 2024-05-10'. These labels help tools like Google understand your content better, which can lead to richer search results, better recommendations, or improved accessibility for screen readers.

- Omitting mandatory fields even if they seem optional
