Make page structure clear for users and search engines
Headings work like a table of contents for a page. Users scan them to find the section they need, and search engines use the H1 to H6 flow as one signal for understanding the body structure. When the hierarchy is unclear, useful content can feel harder to follow.
Paste HTML to check H1 count, starting level, skipped heading levels, empty headings, and headings that are unusually long. The outline is shown in the same order as the page, making it easier to review the section flow before publishing.
The check runs inside your browser. Pasted HTML is not sent to berryfy. Treat the result as an automated review, then also read the final headings from a user perspective to make sure the page still feels natural.
