Auto Manufacturers are constantly arm wrestling over PPC rankings. In Jan-Feb the website AdGooroo reported that, “177 automotive manufacturer sites sponsoring keywords on U.S. Google Desktop/Tablet in January and February this year. Of those, the top 20 sites (representing approximately 11%) drove 81% or 11.7 million of the 14.4 million paid search clicks in the category during the period.”
The winners in the desktop space? Toyota.com and BuyToyota.com controlled the most "Share of Voice" during this period with Ford.com, Chevrolet.com and Honda.com on top as well.
On mobile devices it was Chevrolet.com and Toyota.com, but Dodge.com and NissanUSA.com controled a larger "Share of Voice" than they had on Desktop/Tablet.
