Generic top-level domains
Generic top-level domains (gTLDs) are domains that aren't associated with specific locations. If your site has a generic top-level domain such as .com, .org, or any of the following domains, and wants to target users in a particular geographic location, explicitly set a country target using one of the methods described previously.
