Duplicate Content
Duplicate content is identical or very similar content available at more than one URL – a common issue on international websites.
What is duplicate content?
Duplicate content is identical or very similar content that is available at more than one URL, on the same website or across different sites. Typical causes are URL parameters, HTTP and HTTPS or www and non-www versions, printer-friendly pages, product variants – and, on international sites, the same language for several countries.
Contrary to a common myth, Google does not penalize duplicate content as such. The problem is a different one: the search engine picks one URL as the original and filters the others out. That may not be the version you want to rank, link signals are split between versions, and crawl budget is wasted.
International websites run into this when, for example, Germany, Austria and Switzerland get almost the same German page, or Mexico and Colombia the same Spanish one. Best practice:
- Mark each country version with hreflang tags so search engines understand they target different markets.
- Give every version a self-referencing canonical tag – don’t point all versions to one country, or the others drop out of the index.
- Differentiate where it matters for users: prices and currency, contact details, delivery terms, local examples and spelling.
Outside international setups, consolidate true duplicates with 301 redirects or canonical tags, and keep only one indexable URL per piece of content.
