There are many URLs that require parameters to load a resource (and aren’t necessarily tracking anything). With YouTube’s non-shortened links (for example), the video ID is after the ?, but is usually (but not always) immediately after.

This:
https://www.youtube.com/watch?v=dQw4w9WgXcQ

Can be shortened to:
https://www.youtube.com/watch?v=dQw4w9WgXcQ

But no shorter.
