AdClarity scanned the entire Internet during the last six months to find out where General Motors, McDonald's, Amazon, Best Buy, Wells Fargo and seven other brands were getting the biggest "share of voice" as advertisers. In other words, the media software and marketing services company unearthed the handful of publishers showing the brands' ads at highest clips.

Interestingly, many ads are landing on websites that don't appear to make a ton of sense. In just one example, three of Wells Fargo’s five biggest "share of voice" sites were from India.

Meanwhile, AdClarity's findings at least partly reveal strategies for the aforementioned retail players going into the holidays as well as the seasonally busy carrier FedEx.

UPDATE: An earlier version of this story wrongly suggested the data was related to ad spend.
