A geodomain is a website domain name that includes the name of a specific place, like a city or state, within it. For example, if you made a website about cool things to do in New York City and named it "CoolThingsNYC.com", that would be a geodomain. Geodomains are useful because they make it clear to people that your website is all about a particular location. It's like putting a label on a box so you know what's inside without having to open it up. Plus, if someone is searching for information about a specific place online, a geodomain makes it more likely that your website will come up in their search results.
