Duplicate content detected: what it is, why it matters, and how to fix it
This page has substantially similar content to one or more other pages on the site (typically >85% similarity). Search engines may struggle to determine which version to rank.
Where this fits: indexability in SEO
Why duplicate content detected hurts your rankings
Duplicate content splits ranking signals (links, engagement) across multiple URLs, weakening each page's ability to rank. Google will typically choose one version to index and suppress the others, but may not choose the version you prefer. Extensive duplication also wastes crawl budget.
This is a high-severity issue: it directly suppresses rankings or click-through on the pages it affects. It belongs in your current sprint, prioritised by how many pages carry it.
How to fix it
Consolidate duplicate pages by choosing one canonical version and either redirecting the duplicates with 301s or adding canonical tags pointing to the preferred version. If the pages serve different intents (e.g., location variants), differentiate the content significantly so each page adds unique value.
