YouTube Strategy (Simplified)

Video Ideas (Based on Your Blog Posts)

  1. “AI Security Toolchain Demo” — Walk through the 10 tools from your post
  2. “Log Analysis in 10 Minutes” — Show the baseline script in action
  3. “Home Lab Setup for AI Security” — Screen recording of your setup
  4. “When Something Doesn’t Look Right” — Live log analysis walkthrough

Video Length

  • 5-10 minutes — Start here. Shorter, easier to produce, higher completion rate.
  • 15-20 minutes — Once you’re comfortable. Deeper dives.
  • 30+ minutes — Later. Full tutorials.

SEO Tips

  • Title for search, not clicks — “How to Analyze Logs for Security” beats “You Won’t Believe What I Found in Logs!”
  • Description with keywords — Include the tools, techniques, and topics you cover.
  • Tags matter — Use specific tags: “log analysis,” “security monitoring,” “Splunk,” “SIEM,” etc.
  • Thumbnail with text — Clear, readable text on a dark background works best for tech content.

Upload Schedule

  • Start with 1 video per week — Consistency over frequency.
  • Repurpose blog content — Don’t create new content for video. Adapt what you’ve already written.

Repurposing Workflow

Blog Post (Day 1)
    ├── YouTube Video (Day 3)
    ├── LinkedIn Post (Day 4)
    ├── Twitter Thread (Day 5)
    ├── Newsletter (Day 7)
    └── Reddit Discussion (Day 10)

One piece of content. Six channels. Two weeks of distribution.

The Bottom Line

Start with the blog. Add video later. The blog is your foundation; video is distribution.

Don’t let “I’m not fluent in YouTube” stop you. Your first videos will be rough. That’s fine. The algorithm doesn’t care about your first video — it cares about your 50th.
