Duplicate Content
Identical or near-identical content on multiple URLs splits ranking signal. Here's how to resolve it.
What it means
Multiple URLs serve substantially the same content. Common with URL parameters, print versions, and trailing-slash variants.
Why it matters
Google has to pick one URL to rank — the others get filtered. The wrong one might win.
How to fix it
- Identify duplicate URL groups in the audit.
- Pick a canonical URL for each group.
- Add <link rel="canonical"> on duplicates pointing at the master.
- Or 301-redirect duplicates to the master if they have no unique value.
