There are various options when operating internationally: same root domain, different top level domains, subdomains, how to link between them, how to simplify the process without negatively affecting your SEO.
An Audit and careful planning will help you set-up an effective SEO strategy depending on your requirements and resources. Make sure the language meta tags and settings the Search console are set-up, evaluate any possible SEO damage if using client-side rendering with a mixed url structure.
Same domain domains, multiple languages
If you are using the same root domain for internationalisation, you will be concentrating your backlink efforts to one main domain. However the complexity is to be dealt with. For instance hreflang need to be implemented, avoid any duplicate content, use canonicals when necessary.
One domain per language
If you are using different top level domains for internationalisation, there are pros and cons compared to same root, effectively easing complexity and building a local identity with the possibility to optimize server location. However, you will need to make sure to link them from your master domain, and manage different backlink strategies for each domain.
