URL parameters are a way to pass information about a click through a URL.
Here’s an example of a URL with URL parameters:
URL parameters appear after a question mark symbol (?) in a URL. Each URL parameter contains two parts – a key and a value. The key and the value are separated by an equals sign (=). In the example, ‘product’ is a key and ‘1234’ is a value.
If you have multiple URL parameters, these are joined by an ampersand (&). In the example, ‘product=1234’ is the first URL parameter and ‘utm_source=google’ is the second URL parameter.
In the example, the parameter ‘product=1234’ would modify the content to show a certain product to the user. The parameter ‘utm_source=google’ would track that the user had come from Google.
