I get the saddest feeling when I see a thumbnail of a video with a image and byline that looks interesting, I hover to preview and then move on. It has usually been recently uploaded in the last few days or weeks, sitting on a very low view count, it is of interest to me, it looks lengthy and may have been a lecture or institute upload, it looks to be of high content or production quality.
Alas, I move on. I already know how to make a PCB at home within 30 minutes, I know how to make a ESP8266 range extender and IOT device, I have already been introduced to the ESP32-Cam and don't need another tutorial. Sadly, I won't click the link, I won't like, I won't subscribe, I will move on.
If you want to make money via youtube advertising then your content needs to go viral.
