Active and passive parameters
The URL Parameters tool categorizes parameters as either active or passive:
Active parameters
Active parameters can change page content. Examples include parameters such as brand, gender, country, and sort order. Here are some common types of transformations created by active parameters:
Sorting (for example, sort=price_ascending): Changes the order in which content is presented.
Narrowing (for example, t-shirt_size=XS): Filters the content on the page.
Specifying (for example, store=women): Determines the set of content displayed on a page.
Translating (for example, lang=fr): Displays a translated version of the content.
Paginating (for example, page=2): Displays a specific page of a long listing or article. Note that you can also indicate paginated content directly.
Passive parameters
Passive URL parameters have no effect on how content appears to the user; they are often used to track visits and referrers but have no effect on the actual content of the page. For example, the following URLs all point to the exact same content:
http://www.example.com/products/wome...essionid=12345
http://www.example.com/products/wome...essionid=34567
http://www.example.com/products/wome...rce=google.com
Some examples of passive parameters include: session, affiliated.
