Saying your click through rate sucks is one thing, but we have no real context into how much they "suck"
How many actual impressions have the videos gotten?
My main question is what's the actual demand for the topics you're covering? Are these videos that are actually being search or trending in your niche, or are you doing them just because you want to, and HOPE others will want to watch. I've had the issue where I've wanted to make content because I thought it was cool, with no real research behind it, just felt like it for the sake of making some content that intrested me. Then later discovered the topics themselves weren't searched for and just weren't interesting to my audience.
I'm also starting to notice a corrolation between impressions, and audience retention. search impressions are one thing, but suggested impressions are completely different. My gut tells me that suggested and browse impressions are effected by your videos audience retention and completion percentage. The lower the audience retention/completiton percentage, means that people weren't interested in watching your content to the end, so they left early in, telling YouTube that audiences aren't interested in watching, meaning they aren't going to recommend the video out further. This is the issue I'm having with my content, which can be improved with better video crafting.
If the audience retention is good, and search impressions are low, then it's possible that the topics you cover aren't searched for that much, or you need to consider a different approach.
My search impressions are decent, but my suggested impressions tanked in 2018 when there was a shift to audience retention being most important. My videos have poor audience retention, so thats why my suggested impressions tanked. Which means I have to make better more interesting videos. It's a tough craft to learn but you get better gradually over time.
