Where do I redirect a domain to strengthen another domain?

[JCorp]

I've got a UK domain that I need to redirect to a US domain. Should I point it to the root domain or a landing page off the root and what it the benefit to doing one over the other?

you should redirect it to the content that best matches the original URL. if it is a product page send it to a product page. etc.

Thanks for the reply. The content on the root domain would match the original URL, so I would be good there. In theory, would redirecting to the root domain also strengthen domain authority?
