Yes, bike reviews tend to do well, as that's what people usually search when they want to buy a bike, however, there are plenty of other ideas around the bike:
- initial bike review / first impressions
- few things you like about the bike
- other things you don't like about the bike
- 6 months owners review
- reviewing other bikes if you can test ride something else
So these are more or less related to review the bike as a whole, either yours or others. But then you move into other topics more related to the mods you've added or in my case I'm planning to add, and I definitely know there is a demand for these because I've done some keyword research. Things like
- exhaust comparison
- exhaust sound.
- lots of people have asked me what windscreen do I use and if it helps. Guess what my next video will be about?
- One of the things I didn't like about the bike was the seat, so I'm planning to create another video on how I fixed that.
- planning to install some bar end mirrors - so I'll have a video on this as well.
- Pretty much every single mod/accessory you've added, I'm sure there is someone out there who's looking for some sort of information on it.
So these will be the main things which are very keyword focused, bringing lots of view, or at least thats the plan. Once the views are in.. That's your opportunity to guide people to some of your other videos which might not be that keyword focused, things like motovlogs, and just random topics you might want to talk about while riding your bike.
Regardless of whether someone has subscribed or not. Can't tell you how many times I haven't subscribed to a channel, but because I've watched a video or two, now I'm seeing some of their other videos either or home or suggested.
And on top of that, you can add some entertainment videos (if you have any) like compilation of close calls, stupid drivers.. OR maybe you live somewhere with some nice twisties /scenery like Schaaf, , or perhaps your commuting to work like RoyalJordanian in a busy town and you're doing a bit of filtering... so these can be videos where you don't even have to talk.
And moving away from topics, YES thumbnails and titles are very important to get more views. 50% of my views are actually from Home, 22% from Suggested, and another 20% from Search.
What else can you do to get even more views? Use end screens, cards, pinned comments, even a video's description to link to another highly relevant video. Doing this will also signal Youtube and help you appear in Suggested.
Engagement generates more views. If people are engaged with your content, they comment and all that, which signals Youtube that your video is good, so that will bring more views. So plan your content in a way that you get the viewers involved, ask a question, ask for their opinion, etc...
