Welcome to the Q&A Forum

OZNAPPIES' idea is a good one, and the technical advice is totally sound. Here's another idea: show the English language homepage by default, but determine the user's preferred language. If your site supports the identified language, include & display a hyperlinked text-box/graphic-banner suggesting the visitor "view this site in {the user's identified language}" which links to the homepage for that language. Regarding which country gets the SEO rank for the "domain.com" - it depends on where your links come from, your overall domain authority, the page authority for your targeted page, and the geolocation factors referenced here. The same site could rank well in multiple countries, by the way. For example, this page on "diagnostic troubleshooting" ranks well in the U.S., the U.K., France, etc. However, if you have the resources to make targeted sites for each language/territory, I recommend you do that.
