Your customer is considering their reports and notices that Search Ads 360 is using a previously generated basic linear attribution model to track conversions instead of the data-driven attribution model they set up last week. Why might Search Ads 360 be defaulting to the previous model?

• The number of clicks and conversions falls below the data requirements.
• Historical data is transferring to the new model created.
• The model was created during the bid strategies learning period.
• There are too many keywords included in the bid strategy.

The correct answer is:

• The number of clicks and conversions falls below the data requirements.
