Not asking about the obvious end goal metric. I mean the leading indicator you personally trust most in the first 48 hours before you have enough conversion data to make real decisions. CTR as a proxy for creative relevance? CPC as a signal of competitive position? Engagement rate? Time on site? Curious what experienced buyers are actually watching in those first two days when conversion data is too thin to mean much. submitted by /u/Upbeat_Quit7362 [link] [comments]
