Duplicate content
What is duplicate content?
Duplicate content is identical or very similar content accessible at multiple URLs. Google must decide which version to display — and it often chooses the wrong one or lowers the rankings of both pages.
Causes of duplicate content
The most common causes: a site accessible with and without www, HTTP and HTTPS versions, URL parameters (?sort=, ?page=), print versions, and content scraping by other sites. CMS platforms often generate duplicates automatically (tags, categories, archives).
How to fix duplicate content?
Use a canonical URL (<link rel="canonical">) — point Google to the preferred version. Implement 301 redirects for duplicates. For URL parameters, use noindex or configure them in Google Search Console. Create unique content for every page.
