什么是转化延迟时间？

Conversion lag is the time elapsed between a user's initial ad click and their completion of a conversion action on the website, or the time until an advertiser uploads an offline conversion. Understanding conversion lag is crucial for accurate performance measurement and optimizing bidding strategies, especially for Smart Bidding, as it helps account for the full conversion path. The other options are incorrect because: The first option describes a "ramp-up" or "learning period" for Smart Bidding, not conversion lag. The second option refers to the time taken to set up a measurement strategy, which is unrelated to the time between an ad click and conversion. The third option describes page load time, which is a component of user experience but not the definition of conversion lag.
