Why is my CTR dropping as my video gets more views?

The Diagnosis

This one panics creators constantly, and it's almost always the system working. Early on, your video shows to the warmest possible audience — your regulars, your topic's core. As it performs, the platform spends impressions on progressively colder circles: casual viewers, adjacent interests, total strangers. Colder audiences click less. So CTR falling while impressions climb isn't your package weakening — it's your package being tested on harder rooms, which only happens when the earlier rooms said yes. The honest read: CTR and impressions together, always. Falling CTR + exploding impressions = expansion. Falling CTR + flat impressions = an actual packaging problem worth fixing. And check your doors before either conclusion — a push into feed traffic drops CTR by physics, because cold doors always click lower than search.
