Keep the Outline Logical
Use a single H1 for the page topic, then cascade naturally through H2 and H3 sections so crawlers understand content hierarchy.
Heading Structure Analyzer
Analyze H1 to H6 hierarchy from a live URL or pasted HTML to find missing H1 tags, skipped levels, and duplicate headings.

Remote fetch uses a client-side proxy. For heavily rendered pages, use the HTML tab and paste the page source.
Avoid Level Skips
Skipped levels such as H2 directly to H4 make content harder to parse for both accessibility tools and search engines.
Use HTML for Rendered Pages
Check the live URL when possible, but keep the HTML tab handy for JavaScript-heavy pages that do not expose headings through a simple fetch.
