Frequently Asked Questions

One H1 per page is best practice. The H1 should contain your primary keyword and clearly describe the page topic. Multiple H1s are technically valid HTML5 but can confuse search engines about the page's main topic.

Search engines use header tags to understand content structure and topic importance. A logical H1→H2→H3 hierarchy helps crawlers index your content correctly. Skipping levels (e.g., H1 directly to H4) makes structure unclear.

Yes, but naturally. Include primary keywords in H1 and H2, and related/secondary keywords in H3–H6. Avoid stuffing the same keyword in every header — use variations and synonyms for better semantic relevance.
