What is Schema.org Markup?
Schema.org is a collaborative vocabulary that helps search engines and AI models understand the content on your website. It's structured data markup that you add to your HTML to provide explicit clues about the meaning of your content – like whether a page is an article, product, recipe, or event.
When properly implemented, schema markup enables rich snippets in search results (star ratings, prices, event dates), helps AI models cite your content accurately, and improves your visibility across Google, Bing, and emerging AI-powered search engines like Perplexity and SearchGPT.
