A Header Tag Checker is an SEO tool that crawls a webpage and extracts all of its HTML heading tags, from H1 down to H6.
In web design, heading tags are used to define the structure of a page. The H1 acts as the main title, H2s act as chapter headings, and H3s to H6s act as sub-sections. This tool gives you a bird's-eye view of your page's outline, making it easy to spot structural mistakes that search engines might penalise.
