Great question! When you short a link, e.g. a download or an interesting site with ytsubme.com, all users first have to do whatever you want them to if they want to continue to the target site, like subscribe to you, or like a video of yours."
We would usually suggest you to put it in your video descriptions , but as per my personal usage if you have another website , just tell users to come to your website and send users to ytsubme.com links from there !works 100%
Make sure you are using "https://" before the links as prefix for example
youtube channel url should be like : https://www.youtube.com/channel/ucf0pvplsi8r5kcaqgtorqoa
Target Url Should be like :
