Which of the following metrics would be the strongest indicator of a campaign's ability to help drive consideration?

Detail page view rate is the strongest indicator of consideration because it directly measures how often customers view a product's detail page after seeing an ad. This action demonstrates an active interest in learning more about the product, which is a key step in the consideration phase of the customer journey. Add-to-cart, while a strong indicator of intent, occurs later in the funnel, closer to conversion. Units sold is a conversion metric, indicating a purchase has already been made, not consideration.
