You have an opportunity to enter a domain in several places in Hawkeye. Simply, a domain is a website or URL.
It's the name (usually ending in something like .com, .org, .gov, .fr, etc) that people type in a browser bar to get to a website.
Keep in mind: some brands have multiple domains. Ask yourself: is our blog hosted on a different domain? Do we have a third party content source that impacts our content strategy?
