Page structure finder.
Paste the HTML of any page and see its headings as an outline, the way a search engine or screen reader reads the page structure.
About this tool.
Headings (h1 to h6) are the outline of a page. They tell visitors, screen readers and search engines what the page is about and how it is organised. Common problems are a missing or repeated h1, jumping from an h2 straight to an h4, and empty headings left behind by a page builder. This tool lists every heading in order, shows the outline, and flags those problems. Browsers do not allow a web page to fetch another website, so you paste the page source instead. It is read in your browser and nothing is uploaded.
- Open your page, press Ctrl+U (or right-click and choose View page source), select all and copy.
- Paste it into the box, or upload a saved .html file. The outline appears straight away.
- Read the checks, fix any problems in your page, and paste again to confirm.
Nothing is uploaded. The page is read inside your browser. 534 characters.
Good to know: If your page is built with JavaScript, View page source can be almost empty. In that case open the browser inspector, right-click the <html> tag, choose Copy outerHTML and paste that instead. Headings should describe the content, so do not use them just to make text bigger.
