Notes: Smartphones have the highest click-through rates across search, social and display ads, finds Marin Software in a review of the Q3 performance of enterprise-class marketers who spend in excess of $1 million annually on paid search, social and display channels. When it comes to conversion rates, though, desktops reign supreme across each of the channels. Separately, the study notes that tablets account for a larger share of conversions than spend across search and display channels. Notably, while mobile devices captured more than 60% of social ad spend, they accounted for only about 35% of social ad conversions.
