Heading Analyzer

The Heading Analyzer parses your HTML or plain text to visualize the full H1 through H6 heading hierarchy, catch structural gaps like missing heading levels, and score your page's heading architecture for both SEO and accessibility. Headings serve a dual purpose in modern search optimization: they provide semantic structure that helps Google understand the topical organization of your content, and they create scannable anchor points that keep readers engaged on the page. A well-structured heading hierarchy directly improves your chances of earning featured snippets, because Google frequently pulls content from pages with clear, logically nested headings that answer specific questions. The most common mistakes this tool catches include using multiple H1 tags on a single page, skipping heading levels (jumping from H2 to H4, for instance), and using heading tags for styling purposes rather than structural ones. When you review your results, start with the structure score: anything below 80 suggests significant issues that need attention. Verify that you have exactly one H1 tag that contains your primary keyword, followed by H2 tags for each major section, and H3 tags for subsections within those sections. The keyword presence check tells you whether your target terms appear in enough headings — ideally your primary keyword shows up in the H1 and at least one H2, while secondary keywords are distributed across the remaining subheadings. Headings also matter for accessibility because screen readers use them to navigate page content, so a logical hierarchy is not just an SEO best practice but a legal compliance consideration under ADA guidelines. Pro tip: mirror the heading structure of the current top-ranking page for your target keyword, then add one or two additional subsections that cover angles competitors have missed.
