What the Last 30 Days of Reddit Data Say About YouTube Topics
Reddit is one of the best leading indicators for YouTube topics. Discussions on subreddits like r/technology, r/artificial, and r/LocalLLaMA often precede YouTube search spikes by 2-4 weeks.
We tracked 30 days of Reddit data to identify what topics are gaining momentum—and more importantly, which ones YouTube is underserving.
The Signal: Velocity Over Volume
Raw upvote counts are misleading. A post with 2,000 upvotes from last week matters less than a post with 500 upvotes from 2 hours ago.
That's why we measure velocity:
Velocity = (Score + Comments × 2) / Age in Hours
Comments are weighted 2x because they indicate deeper engagement—people taking time to discuss, not just scroll past.
Current High-Velocity Topics
| Topic | Velocity | Source Subreddits | Gap Score | |-------|----------|-------------------|-----------| | MCP Protocol | 156 | r/LocalLLaMA, r/ClaudeAI | 91 | | AI Agent Reliability | 89 | r/artificial, r/programming | 80 | | Local LLM Cost Analysis | 67 | r/LocalLLaMA, r/selfhosted | 82 | | Claude Code Tips | 78 | r/ClaudeAI, r/programming | 88 | | Multimodal API Pricing | 45 | r/OpenAI, r/artificial | 74 |
The Gap Score measures how underserved the topic is on YouTube—high scores mean lots of Reddit buzz but few videos covering it.
Deep Dive: Top 3 Opportunities
1. MCP Protocol (Gap Score: 91)
Anthropic's Model Context Protocol is generating massive discussion on Hacker News and Reddit. Developers are excited about standardizing how AI tools connect to data sources.
Why the gap exists: It's new and technical. Most creators are waiting for the dust to settle.
Opportunity: An explainer video right now has almost no competition. First-mover advantage is real.

2. Claude Code Deep Dive (Gap Score: 88)
Claude Code launched recently and developers are sharing tips, tricks, and workflows across Reddit. But YouTube coverage is sparse—mostly first impressions, not comprehensive guides.
Why the gap exists: The tool is new and evolving quickly. Creators hesitate to commit.
Opportunity: A practical workflow video showing real development tasks would stand out.

3. Local LLM Cost Comparison (Gap Score: 82)
The r/LocalLLaMA community constantly debates the true cost of running models locally vs using APIs. But the YouTube content is mostly theoretical—few creators have done real cost breakdowns.
Why the gap exists: It requires actual data collection and analysis, not just opinions.
Opportunity: A data-driven cost comparison would be highly shareable.

Pattern Recognition: What Reddit Tells Us
After analyzing thousands of posts, some patterns emerge:
Topics That Spread Fast
- Comparison debates (X vs Y) generate 3x more comments than standalone reviews
- Cost/efficiency analysis travels across multiple subreddits
- Tool drama (outages, pricing changes, controversies) peaks quickly but fades fast
Topics That Stay Hot
- Practical workflow content maintains velocity longer than news reactions
- "How I actually use X" posts outperform "X just launched" announcements
- Problem-solution threads have the highest comment quality
Using This Data
The gap between Reddit discussion and YouTube supply is where opportunities live. Here's how to use this information:
-
Track velocity, not just upvotes. A fast-rising post matters more than a stale popular one.
-
Look for question patterns. When the same question appears across multiple threads, that's unmet demand.
-
Check YouTube supply. Before committing, search the topic on YouTube. How many recent videos exist? Are big channels covering it?
-
Move fast on high-gap topics. The window for low-competition topics is usually 2-3 weeks.
The Lead Time Advantage
Reddit discussions typically precede YouTube search trends by 2-4 weeks. If you catch a topic in its "rising" phase on Reddit, you can have a video ready before most creators even notice the trend.
This is the core principle behind trend scanning: be early, not reactive.
The data is clear about what topics are heating up right now. The question is whether you'll be making content about them before or after everyone else.
