I have no idea what the video is about from the thumbnail as I don’t know what the notebook thing is so I’d be tempted to go with text such as ‘simplify you live with this free tool from Google’ or ‘Content creators, get organised with this free tool’ You can put the name of the tool in the title and description to support the thumbnail and for seo. It also looks a bit power pointy/business like. Take a look at the top videos in your niche - thumbnails are often simpler with bold white or yellow text with a black outline. Good luck :)

I just post around once a week when the video is finished. I've found zero difference between when I post to the success. YouTube will serve it to people who it thinks will like it regardless of what time you post. The most important thing is making sure the title/description/tags mean it can get to the right people through SEO.

I agree value is one, but you also need to be able to delivery the message in a clear and structured way + hold the viewers attention.

@Robert Chandler I think because they help others in the same situation, it's like a 'heads up' for potential issues you can face when buying a house and learning from my personal experience.

I play the piano and I have a piano channel. I would say that the layout of the videos makes it difficult to follow along. The piano should be at the bottom, with the piano showing the keys you are playing above. I wouldn't bother putting the video of you playing unless you are using it as an example of what you will be teaching, before showing the closer shots of the keys. Also, as a piano player, I'd never play these songs. You could try some popular piano music or current popular piano only songs. Get some Christmas songs done! Although, I personally would never learn a song from this type of tutorial as it relies on memorising rather than reading the sheet music and this is hard to follow. The piano channels I watch are the ones that help you learn to play piano pieces by guiding you through the technical aspects of the piece - rather than teaching you each key to play, they use the sheet music and go through things like dynamics, fingering and ornaments to help you take the piece from just hitting the right notes, to getting it to performance standard. Obviously this generally refers to the piano, vs the electric keyboard. I'm unsure whether the keyboard itself is that popular in general. I played the electric keyboard for 10 years as a child, but it seems like it's popularity has declined a lot since the 90s. Are there other keyboard channels around, what are they doing that's popular? Videos that talk about the keyboard, or review keyboards and explain how they work may do well as you do seem to have a few. 'Best keyboards for beginners' type videos would be good, as well as beginners tips or videos such as 'the difference between the piano and keyboards'. Compare brands or talk about why you are passionate about the keyboard in a way that motivates and inspires others to learn. These videos will add value to the viewer. I use my piano channel just as a log of what I've learned, so it doesn't do very well but I'm okay with that. It's just a personal diary for me. That's what a lot of your videos feel like.

Congrats! It's great when a video takes off.
