1.What is creative fatigue in paid social?
The same people have seen the same opening enough times that they stop responding. Hook rate slips, outbound CTR slips, CPA rises, frequency climbs, and comments shift from questions to “I've seen this”. It is not a pixel bug and it is not automatically a dead product. Cold audiences typically show it around frequency 2.5–3.5, faster if the pool is small or the hook is highly distinctive. The creative did its job; the audience finished with that version of the job. Treat fatigue as a scheduled event, not as a surprise. The fix is a new first look, not a post-mortem on the brand.
