Duplicate content
Identical content on multiple URLs forces search engines to choose one and dilutes signals across the copies.
What it is
This check flags different URLs whose main content is the same.
Why it matters for SEO
Duplicates split link equity and can index the wrong URL, weakening the page you intended to rank.
Example
/produit?id=12 and /produit/chaise - same content
How to fix
- Pick one canonical URL and point duplicates to it.
- Use
301redirects where one URL should win outright. - Avoid generating multiple URLs for the same content.
- Re-crawl to confirm duplicates are consolidated.
