More about the Heading Tag Analyzer
A page can look perfectly organized visually while its actual heading structure is a mess underneath, an H1 followed straight by an H4 with no H2 or H3 in between, two H1 tags competing on the same page, headings used purely for their font size rather than to reflect the page's actual outline, all invisible to a sighted visitor but very much visible to a screen reader or a search engine trying to parse the page's structure. This tool analyzes a webpage's full heading hierarchy from H1 through H6 and flags exactly where the structure breaks, a skipped level, a duplicate H1, headings out of logical order. Useful for auditing a page's heading structure before publishing, fixing an accessibility issue where a screen reader user can't navigate a page's headings logically, or confirming a content page's outline actually reflects its heading tags rather than just its visual styling.
