The Problem
Why teams struggle without the right tools.
Invalid JSON-LD Kills Rich Snippets
One typo in your structured data and Google drops your rich snippets. You lose clicks and visibility overnight.
Manual Schema Writing Is Error-Prone
Writing JSON-LD by hand is tedious and easy to mess up. Most schema validators only tell you what's wrong, not how to fix it.
No Schema Coverage Visibility
You have no idea which pages have structured data and which don't. Missing schemas mean missing rich results.
