Here's a little tip:

Put ?sub_confirmation=1 at the end of any YouTube URL.

Example: https://www.youtube.com/channel/UCn8zNIfYAQNdrFRrr8oibKw?sub_confirmation=1

Increases subscription rates by over 200% in my testing.

Really depends on the business, but here's some thoughts:

#1 Audience interaction: The best youtubers interact with their audience in comments on youtube as well as social media. Make them feel invested and they will more likely become supporters. Have thick skin too.

#2 Embeddable links - If youtube subscribers is your target goal, why not optimize your website or different landing pages. You can embed youtube widgets on your page with a subscribe button.

#3 Content Distribution: Yes you're going for subscribers but the more you're content is distributed and the more popular it becomes, the more likely you'll get subscribers. Social media is an essential tool for this.

#4 Use Annotation Buttons In Your Video: More and more people are using creative buttons in their youtube video so that people can skip around to parts of their video, click on another video or in this case subscribe to your account.

#5 Use other video platforms: I see more and more people using Instagram and other platforms with short clips to lure people to their full videos and channels on youtube. This can increase exposure which can result in more subscribers.

#6 Just Ask -many popular youtubers mention subscribing to their channel before and/or after their youtube video for all of their viewers. Be creative and not too aggressive about it.

Remind Viewers to Subscribe To Your Channel

I'm starting to get serious about this myself. All the organic suggestions look like good ones and a great long term strategy.

You can of course advertise via Adwords, which I've found pretty cheap so far albeit at smallish volumes.

I interviewed the guy behind BroScience (850k subscribers) and got 20 tips from him in blog form: http://strategicsauce.com/003

The speed of growth depends a lot on subject matter and how willing the target audience is to share your videos too I think.

I am a growth hacker at Affimity (https://affimity.com), a next-generation social media platform that amplifies YouTubers social reach. We even advertise our organization saying we improve YouTubers social reach and increase their subscriptions and follower base. I want you to try this, it's easy. People who want to increase their subscriptions, need to share their YouTube videos on relevant channels that we have.

I want 1k subscribers what I have to do

It’s frustrating.

When people don’t know how to grow their subscriber base in Youtube, they feel stuck, all the random things they could try to fix their problem seem endless, and they feel alone and overwhelmed…

It’s normal, it is human, and we all have to start small before we grow.

So, here are 5 Great Tactics to Grow Your Youtube Channel in 2020+:

1. You have to snap people’s attention as soon as they click to view your video.

When people are on Youtube, they are skimming the channels, just like when you are at home, watching TV, and frenetically changing channels, giving each just 3 seconds to convince you to stay.

Some people call this a “pattern interrupt,” I call this: the most important part — You have to snap people out of the haze of going from video to video, and to snap their attention so they give you a chance.

One of the best ways I have found to do this is to clap loudly as soon as your video begins. That’s one of the best ways to wake people up and get their attention.

2. Ask people to subscribe in the first 30 seconds and last 30 seconds of your Youtube video.

In communication, people mostly remember the beginning and end of any video. What is in the middle will be a hazy memory within minutes.

So you have to open strong, and end strong.

And how to open strong and end strong if your goal is to increase your subscriber base? Simple: Ask them in a positive, value-adding way to subscribe now at the beginning, and remind them “Don’t forget to subscribe now” at the end.

Because people are less likely to do what you want if they don’t know you want it. So make it clear, ask them to subscribe twice.

3. Tag Influencers.

When you begin your Youtube journey (or even if it had been going on for a while, but your channel is still small), your best option is to get the attention of an influencer, so they notice your videos, and recommend your channel.

And one of the best ways to do this is to tag them on your very best videos, your very best content.

When you tag them there, they get notified in a way that stands out: You’re not one of the 1000s of the messages they receive, you are another fellow content creator tagging them to get their opinion and participation in your topic or video content.

It may not work every time, but when it works, you’ll see a huge influx of subscribers that will put a smile on your face.

4. Humanize yourself.

Youtube is a community. It’s not a library.

If people just want dry knowledge, they’d open a scientific book or university textbook.

But people on Youtube want to listen to the opinions, hear the perspectives, and see the content of other fellow human beings (It’s somewhat what I specialize in, at StoryBonding).

So, you have to be a human first, and a source for content and entertainment second.

A few quick wins to get you started, is to make sure you do at least one small thing every video to come across as a real person:

You can show your dog, play with your cat, talk about your kids, share a hobby you’re passionate about, talk about your favorite music, or your devastation because your favorite team lost last week or your beloved celebrity broke up with the love of her life…

There are many ways to do this, but thats’ a simple way. Don’t neglect this, because people Subscribe first and foremost because they like you and trust you. And people can’t like a moving image on a video screen, you have to be a person.

5. Create videos on topics that are already popular.

When you’re starting, you don’t know what videos people want to want. You don’t know what topics they are interested in.

So, you often will make videos on what you like.

That can work in some cases, but often enough, it doesn’t.

Why?

Because people are interested in what THEY want, not what is interesting to YOU.

You are there to serve.

There is an exception to this, a big one. But if your goal is to get a lot of subscribers, then you can safely ignore that exception and focus on what people want.

Step 1 — Choose a topic you want to write a video about.
Step 2— Search Youtube to see whether videos on the same topic get a lot of views.
Step 3 — If there are videos with a lot of view on that topic, then you continue and create the video. If not, go back to Step 1.

That’s it. Simple and clear.

Because sadly the biggest thing that causes people to feel overwhelmed and to not do what is needed is the lack of clarity: too many contradictory views, too much information, plans with a thousand and one steps.

Use this plan. It’s effective. It works.

Do it. And when you’re done, do it again. Then do it some more.

Then, you will see the subscriber growth you’re looking for.
