H2Common mistakes
The H1 / H2 / H3 contract
One H1 per page, matching the topic. H2s are major sections. H3s nest beneath H2s for detail. Skipping levels (H1 → H3) is bad for accessibility — screen readers announce hierarchy — and weakens the signal Google extracts as jump-link candidates in the SERP.
Pair with on-page checks
Heading hygiene goes hand-in-hand with the keyword density analyser and the anchor text analyser — together they catch the three most common over-optimisation patterns. The why-it-matters breakdown is in heading hierarchy H1 / H2 / H3 rules.
Common findings
- Multiple H1s — usually from CMS templates injecting one then the editor adding another.
- H2 then H4 (skipped H3) — often from styling choices that bypass semantics.
- No H1 at all — frequent on heavily-templated landing pages.
- H2s that don't match what the section actually covers — bad for jump links.
FAQ
Does Google still care about H1?
Yes - but flexibly. Google can rank pages with multiple H1s or no H1. It is still an accessibility requirement (screen readers rely on it) and a clarity signal. Best practice: exactly one H1, matching the page topic.
Is skipping heading levels (H1 then H3) a problem?
For SEO, marginal. For accessibility, yes - screen readers announce hierarchy, and skipped levels confuse navigation. Stick to H1 then H2 then H3 in order.
How many H2s should a page have?
As many as the content needs - typically 3-8 for a long-form article. H2s become the table of contents Google may show as jump links in SERPs.
