Goed om te weten
Headings are not just big text — they form the structural outline of a page, and both search engines and assistive technology depend on that outline being logical. This analyzer extracts every H1 through H6 from the HTML you paste, renders the resulting tree, and flags the three failures that matter most: a missing H1, multiple H1s, and skipped levels such as an H2 followed directly by an H4.
The modern consensus, reflected in Lighthouse audits and accessibility guidelines, is that a page should have exactly one H1 describing what the whole page is about, with sub-sections nested in order beneath it. Skipping a level is a real usability problem because screen-reader users navigate by jumping between headings; a gap in the hierarchy makes the document sound like a section is missing, even when the visual design looks fine. Crucially, heading level should reflect meaning, not font size — style a properly ordered heading with CSS rather than choosing an H3 just because it looks the right size.
A well-formed outline also helps search engines understand topical structure and can improve how your content is parsed for featured snippets. Run this after any CMS or page-builder edit, since those tools love to emit stray or out-of-order headings. To keep the surrounding <head> healthy, pair it with the meta tag generator, and preview how the title and description will read in results with the SERP snippet preview.
Veelgestelde vragen
- Is de koppenanalyzer gratis?
- Ja — gratis zonder registratie.
- Moet elke pagina precies één H1 hebben?
- Ja — dat is de moderne consensus over toegankelijkheid en SEO, en zo verwachten de audits van Lighthouse het.
- Waarom zijn overgeslagen niveaus slecht?
- Schermlezers gebruiken de volgorde van de koppen om hun navigatiestructuur op te bouwen. Het overslaan van niveaus verwart de structuur.
- Worden mijn pagina's geüpload?
- Nee — elke analyse wordt in je browser uitgevoerd.
- Parsed het volledige HTML-document?
- Ja — het parsed alles wat je plakt, body-fragment of volledig document.
