About HTML Schema Validator
Schema markup can be useful, but writing it by hand leaves plenty of room for small mistakes. A missing property, misplaced piece of markup, or simple formatting error can be surprisingly difficult to notice when you're staring at the code.
An HTML Schema Validator gives you a convenient place to check that markup and see if anything deserves a closer look. Instead of guessing where the problem might be, you can review the code and make corrections as needed.
It's especially helpful when adding structured data to a new page or checking an older website. You don't have to turn every small change into a complicated task. Sometimes, having a quick way to test your markup is all you need.
