The conversion date between Google Ads and Google Analytics is different. Why might that be?

Google Analytics attributes conversions to the date the conversion actually occurred, regardless of when the initial interaction (like a click or impression) happened. This is a "conversion date" model. Google Ads, on the other hand, typically attributes conversions to the date of the ad interaction (e.g., the click) that led to the conversion, not the conversion date itself. This difference in attribution models for recording the conversion date is the primary reason for discrepancies. The other options are incorrect because Google Ads does attribute conversions to the date of the ad interaction, and Google Analytics does not attribute conversions to impression dates; it focuses on the conversion event date.
