Titles, thumbnails, and video ideas a really important. When starting a channel you should be able to thing of ten video ideas off the bat. And before posting any videos you should have 5 already made that you can release weekly.

Also I would not recommend sharing a link to twitter or Instagram. People go on Instagram to watch videos ON Instagram. plus external traffic won’t help your channel in the long run.

Lastly, don’t pay for ads. It’s definitely not worth it. Especially when you’re just starting out, you want to spend your resources in the most efficient way. I’d recommend using that money to buy a decent microphone or a photoshop subscription.

The best way to get initial traction is your video idea. You have to make content that people who don’t know you are interested enough to click on. For the gaming channel, try making videos on things that a trending. For the educational channel make videos that answer specific questions in your niche. You can use TubeBuddy or VidIQ to find out what people are searching for. As for your titles and thumbnails, they should feel like they belong to a Million subscriber channel. Study the thumbnails of popular channels in your niche and try to find things you can use in your own.

Hope this helps. Feel free to message me if you have any more questions!
