Duplicate content
Detects pages with identical or very similar content.
Pourquoi est-ce important ?
Duplicate content confuses Google: which page should it rank? This splits ranking power and can lead to cannibalization. External duplicates (from other sites) can lead to filters or penalties.
Comment le corriger ?
Use canonical tags to indicate the preferred page. Rewrite duplicated pages with unique content. Use 301 redirects for exact duplicates. Block URL variants via robots.txt or noindex.
Ce check note de 0 à 100. Sous 50 c’est un échec, 50 à 89 un avertissement, 90 ou plus c’est bon. Après chaque crawl vous voyez la note par page dans le rapport, avec une courte explication.
