Append your Channel URL with SML magic string
This is another smart way to exponentially increase YouTube subscription from people who click on your channel link. In this trick, you will append your channel link with “?sub_confirmation=1”
After: https://www.youtube.com/user/kidrauhl?sub_confirmation=1 (Click on the link to see it in action)
What this does is, when a user clicks on your link with SML magic string (?sub_confirmation=1), they see the pop-up to quickly subscribe to your YouTube channel.
This removes the friction and lets users quickly subscribe to your channel.
You can use SML magic string with tip#2 (above) or also when you add a YouTube channel link on your blog, social media or any other places
