Overview

On-page SEO audit: heading hierarchy, tag counts, meta, images, links and schema, with on-page highlighting.

Heading Hierarchy Checker is a fast, one-click on-page SEO tool. Open it on any web page to see how that page is structured for search. What it shows: - Heading hierarchy: the full H1 to H6 outline, with each heading's font size, so you can spot a missing H1, skipped levels, and empty or duplicate headings. - Tag counts: how many H1, H2, H3, H4, H5, H6 and paragraph tags the page has, plus how many images are missing alt text. Click any count to highlight those elements on the page. - On-page SEO checks: title tag, meta description, canonical, indexability (noindex), mobile viewport, language, Open Graph and Twitter tags, structured data, internal and external link counts, and word count. - On-page highlighting: color-coded labels drawn next to every heading on the live page, showing the tag and its font size, with problem tags flagged. Everything runs in your browser. Page content is analyzed on your device and is not sent anywhere. Use it for quick audits, client site reviews, and catching heading and metadata issues before they hurt rankings. Note: a one-time sign-in (name and email) is required to unlock the tools.
