Jeromy Sonne, a seasoned veteran of the digital advertising landscape, has transitioned from mastering Facebook ad campaigns to becoming a leading authority on ad fraud detection. His firm, Daypart, provides crucial advisory services to advertising agencies and major advertisers, meticulously scrutinizing the accuracy and legitimacy of their digital campaigns. In a recent, in-depth conversation, Sonne illuminated the pervasive reality of modern ad fraud, offering insights into how advertisers can proactively detect and prevent these sophisticated schemes. The discussion underscored that while platforms like Meta and Google have made strides in internal policing, the broader programmatic advertising ecosystem remains a fertile ground for illicit activities, ranging from automated bot impressions and deceptive scam offers to the more insidious use of ad spending for money laundering purposes.
The Evolving Landscape of Ad Fraud
Sonne’s journey into ad fraud detection began after a successful career in Facebook advertising, where he honed his skills primarily in mobile app promotion before shifting focus to e-commerce. His entrepreneurial spirit then led him to found Decibel, an ad tech company specializing in podcast advertising. While Decibel did not achieve its intended success, the experience provided Sonne with invaluable insights into the intricacies of the ad tech industry. It was during this period that he increasingly encountered the detrimental effects of ad fraud, compelling him to dedicate his expertise to combating it.
"My current work at Daypart is about helping advertisers by stopping the bad guys," Sonne explained. "Clients bring me in to investigate the accuracy and legitimacy of their ad spend. It’s been more successful than anything I’ve done before because it addresses a fundamental problem that erodes advertiser trust and return on investment."
Ad fraud, Sonne elaborated, is a broad term encompassing a spectrum of deceptive practices. At its most basic, it involves billing advertisers for impressions generated by bots or for clicks that are not from genuine human users. However, the sophistication of these schemes extends far beyond mere automation. Advertisers might find themselves paying premium rates, such as a $30 CPM (cost per thousand impressions), only to discover their ads have run on low-quality, untrustworthy websites rather than the premium placements they were promised. At the extreme end of this spectrum lies the use of ad networks for money laundering, where criminals establish shell companies to purchase advertising from themselves, effectively legitimizing illicit funds.
Programmatic Networks: The "Wild West" of Ad Fraud
When questioned about the prevalence of ad fraud on major platforms like Meta and Google, Sonne drew a distinction between these "walled gardens" and the broader programmatic advertising networks. While no platform is entirely immune, he noted that programmatic advertising, which involves the automated buying and selling of digital ad inventory in real-time, is significantly more vulnerable.
"It’s worse for so-called programmatic ads," Sonne stated. "Meta and Google, for example, are nominally better because they have more control over their own ecosystems. Their internal teams are generally more responsive to fraud detection and remediation. However, the programmatic ecosystem is incredibly complex, especially when you’re dealing with sophisticated criminals actively trying to evade detection."
The sheer volume and decentralized nature of programmatic ad exchanges create numerous entry points for fraudulent activity. This complexity allows for a wider array of scams, from those perpetrated by individuals posing with luxury vehicles in online advertisements to more intricate schemes that may start with a legitimate offer but gradually evolve into fraudulent operations. Sonne emphasized that for advertisers seeking to maximize their return on ad spend (ROAS), eliminating fraud is paramount. "The best way to increase your return on ad spend is to cut out fraud. Real ads going to real humans is the best optimization tactic," he asserted.
Quantifying the Invisible Threat: Bot Impressions and Suspicious Pages
For advertisers who, like Eric Bandholz of Beardbrand, primarily invest their entire ad budget on platforms like Meta, understanding the potential scale of fraud is critical. Sonne addressed this by highlighting specific areas within Meta’s advertising ecosystem that warrant closer scrutiny.
"On Meta, you’d look at its Audience Network, which is the Wild West of advertising," Sonne advised. "Ads on mobile apps are generally higher risk." He acknowledged that Meta does periodically identify and remove fraudulent activity. "Occasionally Meta might wipe out, like, 10% of clicks or impressions because they were bots. That could include AI agents or bots using a human’s account."
However, Sonne reiterated that the problem is considerably more pronounced on the "open web" – encompassing display ads, video ads, and mobile apps outside of the major walled gardens. He provided a stark estimate: "Upwards of one-third or more of ad spend is likely fraudulent to some degree, especially on programmatic networks." This statistic underscores the significant financial drain that ad fraud can represent for businesses of all sizes. The implications of such a high percentage of wasted ad spend are profound, impacting marketing budgets, campaign performance, and ultimately, business growth.
Unmasking Deception: The Art of Transparency and Verification
The question of how advertisers can discern fraudulent clicks and impressions from legitimate ones is central to combating this pervasive issue. Sonne advocates for a rigorous approach centered on transparency and meticulous data analysis.
"Transparency is the key," he stressed. "Given enough data, you can start to put things together." Sonne shared a real-world example of his investigative process: "I was looking at a set of mobile ads recently and, at first glance, they seemed legit. Then I dug into the devices they were running on. These were all supposedly running on iPads with Intel chips, but iPads never had Intel chips. The publishers were clearly spoofing devices, using a workaround, running a bot farm, or something similar. So put on your Sherlock Holmes hat and look for patterns or claims that don’t add up."
This anecdote illustrates the importance of what Sonne calls "trust but verify." Advertisers should not blindly accept the metrics provided by ad platforms without independent verification. Even within platforms like Meta, where advertisers can implement certain controls, such as blocking shady apps on the Audience Network or utilizing their own ad servers to cross-reference data, discrepancies can and do arise.
"Even Meta has this problem," Sonne admitted. "An advertiser can block shady apps on the Audience Network or even use its (the advertiser’s) own ad server and look for discrepancies between that and what the ad platform says. There’s no magic bullet; it’s trust but verify. When you have a discrepancy, call it out and work with the ad platform to get a refund." This proactive approach, involving diligent data review and a willingness to challenge platform reporting, is essential for advertisers aiming to safeguard their investments.
When to Call in the Experts: The Threshold for Fraud Detection Services
The decision of when to engage specialized fraud detection services like Daypart is a significant one for many businesses. Sonne typically works with agencies and large advertisers that have reached a certain scale of investment, particularly in the open web programmatic space.
"I generally work with agencies that are spending several million per month on open web programmatic ads, such as connected television and audio," Sonne clarified. "That’s after they’ve tapped out Meta and Google." This suggests that companies with annual ad expenditures ranging from $25 million to $50 million are often the most likely to find the cost of his firm’s services justifiable.
"Advertisers solely on Meta and Google are typically below that," he added, reinforcing the idea that while fraud exists on these platforms, the larger, more complex programmatic networks present a greater and more costly challenge. Sonne also acknowledged the efforts of some larger entities in improving the integrity of their platforms. "I have a lot of respect for Comcast. Beeswax, Comcast’s programmatic buying platform, is tightly run."
However, for many businesses, particularly those with substantial programmatic investments, the prudent choice often involves partnering with an experienced agency that possesses the expertise to navigate the complexities of ad fraud and implement effective preventative measures. "The safer bet is to work with an agency that knows what it’s doing and can stop fraudulent activity," Sonne concluded.
Navigating the Future of Advertising Integrity
The continuous evolution of digital advertising necessitates ongoing vigilance against ad fraud. As new technologies emerge, so too do novel methods for exploiting the system. Sonne’s expertise highlights a critical need for greater transparency and accountability across the entire digital advertising supply chain. The industry’s collective efforts in developing more robust verification tools, fostering open communication between platforms and advertisers, and holding bad actors accountable will be crucial in restoring and maintaining advertiser confidence.
For businesses seeking to understand and mitigate their exposure to ad fraud, Sonne’s advice is clear: stay informed, demand transparency, meticulously analyze campaign data, and be prepared to challenge discrepancies. His firm, Daypart, offers a pathway for those facing significant programmatic ad spend to reclaim control over their advertising investments and ensure their budgets are reaching genuine audiences, not fraudulent schemes.
