Our client wants different domains for different countries where they have headquarters. So we would have www.example1.com, www.example2.us, www.example3.com.br, etc. (it is also multilanguage, with /en/, /es/, /pt/ suffixes).

The content is basically the same, except for the news, which are specific to each country and some other contain (videos, image galleries, etc.)

However, the catalogue of products, corporate pages, etc., are the same.

Will Google (or other search crawlers) detect these common parts as duplicate content? Would it affect SEO performance? How could it be avoided or mitigated?

    Is the content in multiple languages?

  • Yes. But basically the problem is: www.example.com/en/product-one and www.example2.us/en/product-one are identical content. Is that a problem for SEO purposes?

  • Yes. The typical tactic is to chose one and use the canonical tag to reference just one. You can read about it here: support.google.com/webmasters/answer/139066?hl=en with an example under the header : Indicate the preferred URL with the rel="canonical" link element

  • Not if you set the hreflang tags correctly. There's a difference between en_EN and en_US.

  • The problem I see with the suggestion by closetnoc is that the search bot will prefer the canonical domain, so the other domains will be excluded from the search listing. I suspect that 0xCAFEBABE is another approach. I do not understand how big companies can do this without being affected.
