📖 How to Use the Heading Analyzer

The Heading Analyzer helps you audit the heading structure (H1 through H6) of any web page. Proper heading hierarchy is a foundational element of on-page SEO and web accessibility. Search engines rely on headings to understand the topical structure of your content, and screen readers use them to help users navigate pages.

Analyzing HTML Code

The simplest method is to paste raw HTML directly into the text area. You can get the HTML source of any page by right-clicking in your browser and selecting "View Page Source," then copying the entire content. Click the "Analyze Headings" button to run the audit. The tool will parse every H1–H6 tag and generate a detailed report including a summary count for each heading level, a hierarchical tree view of all headings, and a list of detected SEO issues such as missing H1 tags, skipped levels, overly long headings, and empty tags.

Analyzing a Live URL

Switch to the "Fetch URL" tab and enter any publicly accessible web address. The tool will fetch the page's HTML source and automatically analyze its heading structure. Note that some websites block cross-origin requests due to CORS (Cross-Origin Resource Sharing) policies. If the fetch fails, use the paste method instead.

Understanding the Results

• Summary Cards — A quick count of how many headings exist at each level (H1 through H6). Ideally, you should see exactly one H1, a reasonable number of H2s, and progressively fewer H3–H6 tags.
• Heading Structure — A flat list of all headings in document order, color-coded by level, so you can visually scan the hierarchy and spot organizational problems.
• SEO Issues — Automated checks flag common problems: missing H1, multiple H1 tags, skipped heading levels (e.g., H1 followed directly by H3), headings longer than 70 characters, and empty heading elements.

Best Practices for Heading Structure

Always start with a single H1 tag that includes your primary keyword. Use H2 tags for major content sections, H3 for subsections within those sections, and continue nesting logically. Never skip heading levels — going from H2 to H4 without an H3 breaks the document outline. Keep headings descriptive and concise, ideally between 20 and 60 characters. Avoid stuffing keywords; instead, write headings that clearly describe the content that follows. This benefits both search engine crawlers and human readers.
