I publish the blog posts for the technical audience, and the YouTube videos for a living.

And unfortunately, I and all the other YT creators I've talked to have experienced the same thing: a more technical title will give you half or worse in terms of views. You have to play YouTube's game if you want to have any kind of audience.

I find a ton of channels that are buried not because they don't have great content, but more because they don't 'package' it well.

It's something I learned in my programming career: no matter how much I despise marketing, marketing is necessary. And on YouTube marketing is almost entirely the thumbnail and title.

I always take real pictures, show the exact subject and topic covered in the video, etc. — but I stretch the title a bit because that's an immediate way to get 2x-3x the views (and they're not click-away views, either, it's a large portion of the audience who would simply not click at all otherwise).
