URL
A URL is the full address of one page on the internet, like https://yourshop.com/menu.
In a simple example
You copy the URL of your menu page and send it to a friend. They paste it in a browser and see the same page.
Why it matters to you
Short, clear addresses are easier to share and to remember.
Do not confuse with
The domain is only the name part. The URL is the whole address, including the page.
