The YouTube Subscribe Button lets you add a one-click Subscribe button to any page. The button lets people subscribe to your YouTube channel without having to leave your site to either log in to YouTube or confirm their subscriptions.
You need this subscribe button with a hidden subscribe link to get free youtube subscribers to your channel. Like explained in the video, you can customize your subscribe button to either show your current youtube subscriber count or not.
Youtube subscriber count refers to the number of people already subscribed to your channel.
