Welcome to the Q&A Forum

Hi Cassio I would use the .com for the US but you must remember to add an hreflang tag to both sites pointing to each other. This avoids Google thinking that they present duplicate content. Language-Location Read all about it here: https://moz.com/learn/seo/hreflang-tag and here: [https://support.google.com/webmasters/answer/189077?hl=en](https://support.google.com/webmasters/answer/189077?hl=en) Done correctly you won't have any problems. If you then went to other countries you could use subdirectories of the .com so say example.com/es for Spain. I hope that helps Regards Nigel
