The difference in impressions between valid and invalid heading hierarchy is tiny (0.4%). Heading structure alone does not move the needle on impressions.
Bottom line: Heading hierarchy is rarely a ranking lever by itself, but headings still matter for users and crawlers.
The x-axis groups pages by valid vs invalid heading hierarchy. Each bar shows impressions for that group. The gap is about 0.4%, so the bars are nearly the same height. Notice how small this is versus normal page-to-page variation.
SEOs obsess over perfect H1→H2→H3 order. The belief is that clean hierarchy sends a stronger relevance signal and lifts rankings. Across 8K+ pages, valid vs invalid heading hierarchy showed a 0.4% impressions gap. That is tiny versus normal noise from topic, links, and intent match.
Check for multiple H1s and heading jumps on core templates first.
Make each H2 answer a real question users have on that topic.
Use CSS classes for design so headings reflect structure, not size.
Block pages with missing H1 or repeated H1s in your CMS flow.
Make it match the main query intent. Multiple H1s can blur the page topic for both users and systems.
Turn H2s into real subtopics and questions. Vague headings reduce snippet and passage match chances.
Avoid random jumps like H2→H4 for layout. If you do, you add audit noise and slow QA.
Short headings scan fast and fit better in SERP features. Long headings often turn into keyword lists.
You burn dev time for almost no impressions lift.
You create broken outlines and messy section meaning.
You hurt readability and invite rewrites in snippets.
Headings help most when they name the chunk that wins the snippet. Aim for “answerable” H2s like mini titles, then put the direct answer in the first 1–2 lines under it. The level number matters less than the section meaning and the tight answer format.
