A recent study by Google and Ipsos confirms the interest to provide direct phone call after a mobile search, the latter now being a powerful marketing channel. This study reveals the relevance of the Click-to-Call button (literally “click to call”) on results pages when searching via mobile. This is true for both organic results for sponsored or sponsored links. The study was conducted among 3000 users who have recently conducted research on mobile before making a purchase in one of the following 7 areas: travel, food, retail, finance, automobile, outreach and technology.
