A marketing manager is closely monitoring their data to see how effectively their ads are driving online sales and generating leads through sign-ups. When the marketing manager compares Google Ads data with their offline data, they see a difference in the number of sign-ups in Google Ads vs. their offline data source. Assuming everything is working as intended and the issue lies with when a conversion was counted, what's likely causing this data discrepancy?

Google Ads reports conversions against the date/time of the click that led to the conversion. Depending on the other data source, it might use the date/time of the conversion itself.

Google Ads reports conversions against a unique ID of the event that led to the click. Depending on the other data source, it might use the click of the conversion itself.

Google Ads reports views against the device type of the view that didn't lead to a conversion. Depending on the other data source, it might use the date/time of the conversion itself.

Explanation: The likely cause of the data discrepancy between Google Ads and the offline data source is that Google Ads reports conversions against the date/time of the click that led to the conversion, whereas the offline data source might use the date/time of the conversion itself. This option is correct because Google Ads attributes conversions to the date and time when the user clicked on the ad that eventually led to the conversion action, regardless of when the conversion actually occurred. In contrast, the offline data source may record conversions based on the date and time when the conversion event occurred, such as when a user signed up for a service or made a purchase, without considering the timing of the initial ad click. As a result, discrepancies in conversion counts may arise when comparing data from Google Ads, which attributes conversions to the click time, with data from offline sources that track conversions based on the conversion event time. Understanding this difference in attribution methodologies is crucial for reconciling discrepancies and accurately assessing the effectiveness of advertising campaigns across different channels and touchpoints. The other options listed—reporting conversions against a unique ID of the event, reporting views against device type, or reporting clicks against the date/time of the event—do not accurately describe the attribution process in Google Ads and are therefore incorrect choices.
