Conteúdo Duplicado
Duplicate Content refers to substantive blocks of content within or across domains that either completely match or are appreciably similar. In international SEO, this is a major risk when translating content for regions sharing a language (e.g., US vs. UK vs. Australia) without proper tagging.
The Silent Killer of International Rankings
Google rarely shows multiple versions of the same content in search results. If you don't differentiate your US and UK pages (even though both are English), Google will pick one version—often randomly—and suppress the others, killing your local traffic. The solution is proper hreflang implementation combined with small but meaningful localization: change currency symbols, adjust spelling (color vs. colour), swap cultural references, and modify shipping/legal disclaimers. These signals tell Google "these are legitimate regional variants, not spam," preventing duplicate content penalties while maintaining consistent brand messaging.
