Production Gotchas
❌ Following Trends Backfires
The Problem: Trends lose impact within 48 hours, 1/3 find trend-chasing "embarrassing"

The Problem: 79% of Gen Z distrust brands with no visible flaws, UGC trusted 9.8x more
What Breaks: Engagement, trust signals, algorithm performance (platforms favor authentic content)
The Fix: Raw, authentic content. Show process, mistakes, behind-the-scenes. Let micro-influencers create UGC.
❌ Wrong Video Length Kills Reach
The Problem: TikTok: avoid 10-59s (dead zone). Instagram: 30-90s optimal. YouTube Shorts: 24-31s.
What Breaks: Completion rates (primary algorithm signal), resulting in zero reach
The Fix: TikTok: 5-9s OR 60+ seconds. Instagram Reels: 30-90s. YouTube Shorts: 24-31s. Test and optimize per platform.
