Frequently asked questions

Should every page have exactly one H1?
A single H1 per page is the long-standing best practice for clarity and accessibility, though Google has said multiple H1s will not directly harm rankings. Screen readers and outline tools still benefit from one clear top-level heading.
Can I skip heading levels, like jumping from H2 to H4?
Avoid skipping levels. A logical H1 to H2 to H3 hierarchy helps both assistive technology and search engines understand the document outline. Use CSS, not heading levels, to control visual size.
Do headings still affect SEO rankings?
Headings are a relatively weak ranking signal but a strong relevance signal. They help Google identify section topics, generate featured snippets, and pick anchor text for jump-to-section links in the SERP.
