Why heading structure matters
Search engines use headings (H1–H6) to understand page structure and content hierarchy. A proper heading structure helps Google determine topic relevance and improves accessibility for screen readers.
Common issues: missing H1, multiple H1s, skipped heading levels (e.g. H1 → H3), empty headings, and headings that are too long. The Lumina extension checks all of these in real-time and lets you highlight headings directly on the page.
