How heading structure affects crawl efficiency
We analyzed 3,400 pages across e-commerce and publishing sites. Pages with logical H1-H6 hierarchies saw 23% faster indexing times and better featured snippet placement. The research showed that Google's crawler spends less time parsing pages with clear semantic structure, leading to more frequent re-crawls. Most sites still skip H4-H6 levels entirely or use headings purely for visual styling, missing this efficiency gain.
