You Added Schema. But Is It Actually Working?
Adding structured data without testing it is like writing code without compiling it. It might work. Or it might be silently broken.
The Essential Tools
Google Rich Results Test. The gold standard. Paste your URL. It shows which rich results your page is eligible for and flags any errors or warnings. Use this first.
Schema Markup Validator (schema.org). Validates your schema syntax against the schema.org specification. More thorough than Google's tool for catching structural issues.
Google Search Console. The Enhancements section shows schema errors and valid items across your entire site. This is where you see the big picture.
Screaming Frog. Can extract and validate structured data during a full site crawl. Essential for large sites.
What to Check
Are all required properties present? Are there errors or warnings? Does the rendered page (not just the source) contain the schema? (Important for JavaScript-rendered pages.) Does the schema match the visible content?
The Ongoing Process
Schema breaks. CMS updates change templates. Developers remove code they do not recognize. Products go out of stock and availability schema becomes stale. If you are just getting started, our schema markup beginner guide will get you up to speed. For e-commerce, Product schema needs the most attention.
Test regularly. Not just when you first add it.
