HeadingsMap

HeadingsMap is a Chrome extension that helps users browse and audit the headings structure of web documents for accessibility and SEO purposes. It generates a document map or index of any web document that is structured with headings, allowing users to access the content directly by clicking on any of its items. The extension also shows the HTML 5 outline and includes features such as listing headings and sections with optional information about errors in the structure, detecting changes in the DOM, and allowing collapsing of headers by levels. It is a useful tool for web developers, consultants, and auditors.
