About this tool
Heading order is how search engines and screen readers parse structure. Broken hierarchies get flagged with the exact fix.
Why free, and what happens next
Tools like this one are how this desk stays findable: useful first, commercial when you are ready. When a tool surfaces a problem you would rather have fixed than diagnosed, start a project or run the cost calculator first. Everything runs client-side: your data never leaves this page.
