How to Increase YouTube Subscribers by 400% with This Simple Growth Hack

Looking for a growth hack to explode your YouTube subscribers without paid ads or complicated tech? This guide reveals a proven tactic that can boost your subscriber count by up to 400% — instantly. If you're serious about growing your YouTube channel, this one is a no-brainer.

Quick Tips for YouTube Channel Growth

• Adding ?sub_confirmation=1 to your YouTube channel URL triggers an automatic subscribe prompt, making it easier to convert visitors into subscribers.
• This simple trick has been tested and can increase your subscriber rate by 400%.

Here at Gleam we’re always on the lookout for ways to help users grow the metrics that are important to them. YouTube is one of my favourite social networks. I personally think it has a long way to grow — it has a perfect model: content creators get paid to create awesome content.

The easiest way to get that content in front of more users is to either build an email list or grow the number of users that are subscribed to your channel.

This is what a typical YouTube channel or user page looks like when someone visits. Notice the subscribe button tucked away up in the top right corner.

Now this is the exact same subscribe page, with a slight difference. We’re sending users to this page using the following URL:

http://www.youtube.com/user/S2Games?sub_confirmation=1

This small parameter at the end of your URL will show this popup to prompt your users to subscribe to your channel. On average this will improve your subscribe rate by over 400%.

This particular trick will only work on user pages or subscribe pages. So make sure you add it to any links on your website, when you share on social media or when you mention your YouTube channel in emails.

Another incredibly effective way to grow your YouTube audience and increase subscriptions is by running promotional giveaways with Gleam.

All you have to do is give away a prize you think your viewers will love and start driving meaningful user action. Take a look at this template to see what your campaign could look like:
