A query string is a part of a uniform resource locator (URL) that assigns values to specified parameters. A query string commonly includes fields added to a base URL by a Web browser or other client application, for example as part of an HTML document, choosing the appearance of a page, or jumping to positions in multimedia content.
UTM parameters in a URL identify the marketing campaign that refers traffic to a specific website. [1] To define and append the relevant UTM parameters to the appropriate URLs, marketers routinely use simple, spreadsheet-based, or automated UTM builder tools, [3] including the Google Analytics URL Builder for websites.

URL is a useful but informal concept: a URL is a type of URI that identifies a resource via a representation of its primary access mechanism (e.g., its network "location"), rather than by some other attributes it may have. [19] As such, a URL is simply a URI that happens to point to a resource over a network.
Other parameters can be added, such as section=5 or section=new to edit or add a page section. There are also parameters for preloading text into the edit box of a new page, as used by the inputbox extension (see mw:Extension:InputBox ).
However, the order of parameters in a URI may be significant (this is not defined by the standard) and a web server may allow the same variable to appear multiple times. [9] Removing unused query variables. A page may only expect certain parameters to appear in the query; unused parameters can be removed. Example:
In computer hypertext, a URI fragment is a string of characters that refers to a resource that is subordinate to another, primary resource. The primary resource is identified by a Uniform Resource Identifier (URI), and the fragment identifier points to the subordinate resource.
As part of a GET request, some data can be passed within the URL's query string, specifying (for example) search terms, date ranges, or other information that defines the query. As part of a POST request, an arbitrary amount of data of any type can be sent to the server in the body of the request message.
For example, to append action=edit to a URL query string you could use [{{fullurl:Help:Link|action=history}} this page's history], which renders as this page's history. Note that this will render as an external link rather than as an internal link and for this reason it might not appear in what-links-here queries associated with the target page.
