SEO glossary

Duplicate Content

Duplicate content is substantially similar content that appears at more than one URL.

In plain English

It's rarely a penalty by itself, but it forces search engines to choose one version, splitting ranking signals and wasting crawl budget. Common causes are URL parameters, printer-friendly pages, and syndicated content. Canonical tags are the usual fix.

Why it matters for SEO

Duplicates compete with each other, so none of them rank as well as a single consolidated page would.
