Compared to a normal hyperlink, a deep link contains additional information such as a subpage or a link to a partially completed form.

Additional parameters are added to a link in order to filter results or preselect elements.

What is the purpose of URL parameters and deep links?
URL parameters, also known as query strings or “URL query parameters”, are integrated into URLs to filter and structure website content. They can also be used to track user behavior.
Basically, URL parameters are a method of transferring information about the URL with one click.
To identify a URL parameter, the part of the URL that appears after a question mark (?) should be considered. A URL parameter consists of a key and a value, separated by an equals sign (=). If there are several parameters, they are separated by an ampersand (&).
