yeah traffic sources first is right. these cliff drops are almost always browse traffic dying overnight, search never falls off a cliff like thatYeah, I’d first compare impressions vs. CTR, then check average view duration and traffic sources against the period before the drop. I’d also look at whether the drop is across the whole channel or just specific videos, and check for any changes in audience, search demand, or YouTube Studio notifications. That usually helps narrow down whether it’s a content issue, traffic shift, or just normal recommendation fluctuation.
