TikTok creative fatigue at 14 days: the 8-hook rotation that ships 50 variants per month

TikTok creative saturates at 14 days post-launch in 2026 across most B2B SaaS and DTC accounts. CPA rises 30 to 80% past the threshold. The fix: 8-hook rotation across pain, status, identity, fear-of-loss, contrarian, social proof, peer benchmark, and trigger event. Ship 50 variants per month, kill at day 14.
