The link https://is.gd/oArdcv is meaningless. I accidentally clicked it from a page that explained how to logout all Google accounts. This link was translated/redirected to https://myaccount.google.com/device-activity?utm_source=google-account&utm_medium=web which is much more meaningful.
Where can I find more information on how this translation/redirection occurs? What would a random link like https://kjdf.qewr/q34th translate to?
