While it's easy to write off fraud as a rare occurrence and simply focus on accuracy when selling to media buyers, mobile ad providers that do so are at a disadvantage. When examining mobile ad inventory, two questions need to be answered: Are the requests authentic? If so, is the location of the request accurate? Although the question of accuracy relies on the existence or absence of fraud, accuracy of location data is often determined apart from the filtration of fraud. This is problematic when you consider that roughly 16% of requests are fraudulent. And that's just the beginning.
