What does Heading outline checker do?
It helps you inspect or process this value and get a readable result quickly.
Is my input saved?
Local tools run in the browser when possible. Server-side checks only use the input needed to complete the lookup.
Can a clean heading outline guarantee AI citations?
No. Clear H2/H3 structure improves machine understanding and snippet stability, but visibility still depends on crawling, indexing, quality, authority, and platform-specific rules.
How should an AI answer-source page organize headings?
Use H1 to state the problem the page solves. Use H2 for checks, decision criteria, common issues, and fixes; use H3 for steps or exceptions. Avoid repeating headings only for keyword coverage.
How should a rich-result or AI answer page organize H1, H2, and H3?
Use one clear H1 for the page subject, H2 sections for the direct answer, checks, evidence, and limits, then H3 for exceptions or detailed steps. Structured data does not replace visible headings, and a clean outline does not guarantee rich results or AI citations.
