How Much Does Ad Fraud Cost Businesses Each Year? (Stats)

November 17th, 2022

With more people shopping from home since the pandemic, there’s been a global shift towards increased digital spend. And The World Federation of Advertisers now estimates the digital ad market will be worth $500 billion by 2025. 

But wherever money goes, fraud inevitably follows like a dark shadow. In fact, a recent report from the Association of National Advertisers found that ad fraud costs businesses $120 billion globally. And it’s certainly showing no signs of slowing down. For fraudsters, the risks are low and the incentives only continue to grow by the day.

Recently there have been several high-profile ad fraud prosecutions in the US. For example, In November 2021 Aleksandr Zhukov, the self-proclaimed “King of Fraud” was sentenced to 10 years in prison by the US Department of Justice for his role as the lynchpin of the operation dubbed “Methbot”. Aleksandr and several co-conspirators carried out the digital advertising fraud through a fake advertising network Media Methane, hence the name “Methbot”. 

But much like the “war on drugs” law enforcement agencies only successfully prosecute a tiny minority of offenders. The vast majority of digital fraudsters are able to continue running their operations without ever being found out. And it’s costing businesses billions every year, as the stats below attest. That’s why the ad fraud prevention market is growing rapidly. More and more businesses now understand that they need to keep up in the digital arms race against the increasing sophistication of malicious bots and black hat operations.

To help create a clear picture of the scale of the problem, we’ve complied a list of statistics documenting exactly how much money is lost to ad fraud, the mobile advertising fraud landscape, invalid traffic, and click fraud.

Digital advertising is big business. Even after a dip during Covid-19 lockdowns, it accounts for nearly half of all US advertising spend, and a whopping 89% of that is spent on “programmatic” advertising, or ads bought by algorithms. But invalid traffic and click fraud are also big money-makers for fraudsters:

  • Prices for botnet builders now start at $100 (Trend Micro)
  • The average individual ad fraudster makes $5-20 million dollars a year (Forbes)

  • The digital advertising scam named Methbot stole more than $7m (
  • In 2020, Uber reported losing two-thirds of its online ad spend to fraudsters (Statista)
