Memes are very popular around the internet. If you want to get attention on your YouTube channel, you have to make sure your memes are funny for other people to enjoy. Memes also have to be relatable so many people can share it to others. Maybe for the title/description you could write 'Comment if you do this', this way, many people could comment.
This will help! If you don't have a good title, how will anyone want to click on your video? Your video needs to stand out from the crowd. Remember, there are over 2 billion people on YouTube, so make your title something that will make someone want to click on it, or even better, share it! You could add stuff like 'OMG' or 'YOU WON'T BELIEVE WHAT HAPPENED' to your title.
Make sure you upload as much as you can and write down ideas for any YouTube video you might make. If someone subscribes to your channel, they will want to see more of your content. If you don't upload any videos, the person viewing your channel will unsubscribe.
Try to upload different content so that everyone who watches your videos can enjoy it. Maybe you could have 'Monday Memes' where every Monday, you upload memes. Or, you could do vlogs on different things. Make sure you upload videos that you think people will enjoy.
You have to make sure you enjoy your own content! Make sure you have fun making YouTube videos. If you don't enjoy your videos, how can others enjoy it? You need to relate to your audience and in order to do that, you need to upload content that you can relate to.
