What is duplicate content, and does it hurt my rankings?

Duplicate content is pages whose main content is identical or nearly identical — and its real cost isn't a penalty, it's invisibility: Google groups the duplicates into a cluster, picks one page as canonical, and quietly stops showing the rest.

For businesses this usually isn't plagiarism, it's templates: location pages that swap only the city name, service pages that differ by a heading, product variants sharing one description. If pages share too much skeleton and too little substance, Google folds them together.

The fix is genuine differentiation — different intent, different details, different local proof per page — plus consistent canonical signals. And patience: Google's own guidance says re-evaluating a fixed duplicate cluster can take up to two weeks.
