Short links have many advantages, among them
Imagine that you have a large link and want to share it, surely that link will spoil the topics that you post, so here you must use the shortcut links, so that your long link is converted from the large and distorted shape into a link consisting of several letters only.
For example, this link: https://www.youtube.com/channel/UCV04o3AscUaefLtRNbyJh8w
You can shorten the links by converting it to this format: cutx.io/mycnl
The short link will direct everyone who clicks it to the same long link in the example
Also, this will enable you to track the geographical area and the device of everyone who logs in via the short link. This will make it easier for you to know the regions and the types of devices that follow you.
