What is a domain extension?
A domain extension, or top-level domain (TLD), is the ending of a web address, such as .com, .org or .co.
A domain extension is the last part of a domain name, after the final dot. Examples are .com, .net, .org, country endings like .ca or .co.uk, and newer ones like .shop or .law. The technical name is top-level domain, or TLD. Each extension is run by a registry that sets its own rules and prices. Some are open to anyone. Others are limited to certain countries or groups.
Why it matters for your business: Customers tend to guess .com first. If your main domain uses another extension, consider also registering the .com version so visitors and email do not end up with someone else.
