Need advice on boosting impressions/CTR for 3 channels (True Crime & AI Finance) — What am I missing?

Hey everyone,
I’m currently running three different YouTube channels, but I’ve hit a wall when it comes to getting impressions and expanding my reach. I could really use some fresh strategies or a reality check from experienced creators here.
Here is a quick overview of my channels:
Two True Crime Channels: Focused specifically on Death Row cases, historical deep-dives, and narrative-driven storytelling.
One AI Finance Channel: Focused on personal finance, comparison concepts, and modern financial strategies utilizing AI visuals/narration.
My Current Pain Point:
My biggest struggle right now is getting YouTube to push my content out (low impressions) and improving overall channel visibility.
What I’m looking for:
1 Algorithm & Impression Boosts: How do you kickstart impressions on new or stagnant channels in crowded niches like True Crime and Finance?
2 Niche-Specific Tips:
For True Crime (Death Row): How do you stand out when the niche is already quite saturated? Any tips on pacing, thumbnail hooks, or SEO?
For AI Finance: How do you build trust and high Click-Through Rate (CTR) using AI-driven formats?
3 Workflow & Consistency: Balancing three channels is intense. What are the best strategies to maintain high quality without burning out?
If anyone has turned a low-impression channel around or has experience scaling in these specific niches, I’d love to hear your insights.
Thanks in advance for any advice!
