Jeromy Sonne, a seasoned digital advertising strategist who once mastered the intricacies of Facebook advertising, has pivoted his expertise towards a critical and often opaque corner of the industry: ad fraud detection. His firm, Daypart, now serves as a crucial ally for advertising agencies and major advertisers, providing them with vital insights into the accuracy and legitimacy of their digital campaigns. In a recent in-depth conversation, Sonne illuminated the pervasive reality of modern ad fraud and outlined effective strategies for advertisers to both prevent and detect these deceptive practices.
Sonne’s journey into the realm of ad fraud is rooted in his extensive experience within the digital advertising ecosystem. Beginning his career in 2011, he honed his skills primarily in Facebook advertising, focusing initially on mobile app promotion before transitioning to the burgeoning e-commerce sector. This foundational period provided him with an intimate understanding of platform mechanics and advertiser objectives. Following this, Sonne founded Decibel, an ad tech company specifically designed for podcast advertising. While Decibel did not achieve sustained success, the experience proved invaluable, exposing Sonne to the broader challenges and vulnerabilities within digital advertising. It was during this phase that he began to confront the persistent issue of ad fraud, eventually leading him to establish Daypart, a firm dedicated to combating these illicit activities on behalf of agencies and other ad tech entities.
"My work now is focused on helping advertisers by stopping the bad actors," Sonne explained. "Clients engage me to scrutinize the accuracy and legitimacy of their ad placements and expenditures. It’s been a more impactful and successful endeavor than anything I’ve pursued previously."
Understanding the Multifaceted Nature of Ad Fraud
Ad fraud, as Sonne clarifies, is not a monolithic problem but rather an umbrella term encompassing a wide spectrum of deceptive practices. The most straightforward form involves billing advertisers for impressions or clicks generated by automated bots rather than genuine human users. However, the sophistication of these schemes extends far beyond mere automated traffic.
"It can mean billed bot impressions, scam offers, and even money laundering," Sonne stated, underscoring the gravity and breadth of the issue. He further elaborated on the financial implications, describing scenarios where advertisers might pay a premium cost-per-mille (CPM) for ad placements on high-profile content, only to discover their ads were surreptitiously run on low-quality, untrustworthy websites. At the extreme end of the spectrum, ad fraud can be exploited for illicit financial activities, such as money laundering, where criminals establish shell companies to essentially pay themselves for fake ad inventory.
The economic impact of ad fraud is substantial. Industry estimates vary, but reports from organizations like the Association of National Advertisers (ANA) have consistently highlighted the significant financial drain. A 2019 ANA report estimated that ad fraud would cost the global advertising industry $51 billion that year, with projections suggesting this figure could escalate. More recent analyses from cybersecurity firms and ad verification specialists continue to indicate that a substantial portion of digital ad spend is compromised by fraudulent activities.
The Programmatic Landscape: A Hotbed for Fraud
Sonne highlighted a critical distinction in the prevalence of ad fraud, noting that it is generally more pronounced within the programmatic advertising ecosystem compared to the more controlled environments of "walled gardens" like Meta (Facebook/Instagram) and Google. Programmatic advertising involves the automated buying and selling of ad inventory in real-time, often across a vast and diverse network of websites and apps. This decentralized nature, while offering efficiency and scale, also presents greater opportunities for bad actors to operate undetected.
"It’s worse for so-called programmatic ads," Sonne stated. "While Meta and Google are nominally better due to their more controlled ecosystems and responsive teams, the overall complexity of the digital advertising landscape, especially when dealing with sophisticated criminals actively trying to evade detection, makes it a persistent challenge."
The "walled garden" platforms, by contrast, maintain greater control over their inventory and user data. They employ internal systems and dedicated teams to monitor for fraudulent activity and often have more direct mechanisms for addressing and rectifying such issues. However, even these platforms are not entirely immune, particularly concerning their extended networks, such as Meta’s Audience Network, which places ads on third-party mobile apps and websites.
Tactics of Deception and the Role of Scammers
The methods employed by fraudsters are varied and often ingenious. Sonne described instances where individuals might present themselves with extravagant lifestyles, showcasing luxury items like Lamborghinis, as a facade to legitimize scam offers. The deceptive practice can begin with a seemingly legitimate offer that gradually evolves into a fraudulent scheme, making it harder for advertisers to detect the shift.
"The best way to increase your return on ad spend is to cut out fraud," Sonne emphasized. "Ensuring that your real ads are reaching real humans is, in essence, the most effective optimization tactic available to advertisers."
Quantifying the Threat: Bots and Unscrupulous Pages
For advertisers like Eric Bandholz, founder of Beardbrand, whose company allocates its entire ad budget to Meta, understanding the potential exposure to fraudulent traffic is paramount. When asked about the percentage of impressions or clicks that might originate from bots or untrustworthy sources, Sonne pointed to the varying risk levels across different ad placements.
"On Meta, you’d look at its Audience Network, which is the Wild West of advertising," Sonne explained. "Ads on mobile apps are generally higher risk." He noted that Meta occasionally identifies and removes a significant percentage of fraudulent traffic, such as bots or accounts using compromised credentials, which can sometimes represent around 10% of clicks or impressions.
However, Sonne cautioned that the problem escalates significantly on the open web, encompassing display ads, video ads, and mobile apps distributed through programmatic networks. "Upwards of one-third or more of ad spend is likely fraudulent to some degree, especially on programmatic networks," he estimated. This means that a substantial portion of an advertiser’s budget could be spent on traffic that never reaches a genuine potential customer.
The Sherlock Holmes Approach: Detecting Discrepancies
The challenge for advertisers lies in discerning fraudulent activity from legitimate performance metrics. Sonne advocates for a proactive and investigative approach, emphasizing transparency and meticulous data analysis.
"Transparency is the key," he asserted. "Given enough data, you can start to put things together." Sonne shared an illustrative anecdote of examining mobile ad campaigns that initially appeared legitimate. Upon closer inspection of the devices on which these ads were reportedly served, he discovered a significant anomaly: the ads were claimed to be running on iPads with Intel chips. This was a clear red flag, as iPads have historically never been equipped with Intel processors.
"The publishers were clearly spoofing devices, using a workaround, running a bot farm, or something similar," Sonne explained. "So, put on your Sherlock Holmes hat and look for patterns or claims that don’t add up."
Advertisers can employ several strategies to enhance their detection capabilities. Even within platforms like Meta, advertisers can proactively block suspicious apps on the Audience Network. A more robust method involves utilizing their own ad servers to track campaign performance independently. By comparing the data from their ad server with the metrics reported by the ad platform, advertisers can identify discrepancies that may indicate fraudulent activity.
"There’s no magic bullet; it’s trust but verify," Sonne advised. "When you have a discrepancy, call it out and work with the ad platform to get a refund." This diligent verification process is crucial for holding platforms accountable and recovering lost ad spend.
When to Seek Professional Intervention: The Cost-Benefit Analysis
The decision to engage a specialized firm like Daypart hinges on the scale of an advertiser’s digital media spend and the complexity of their media mix. Sonne typically works with agencies that manage substantial budgets on the open web programmatic channels, such as connected television and audio advertising, particularly after exhausting the potential of Meta and Google.
"I generally work with agencies that are spending several million per month on open web programmatic ads," Sonne stated. "That’s after they’ve tapped out Meta and Google." He indicated that companies investing $25 million to $50 million annually in advertising are generally at a scale where the cost of specialized fraud detection services becomes justifiable. Advertisers operating solely within the Meta and Google ecosystems, while still vulnerable, may not yet reach this threshold for external fraud detection services.
"Again, advertisers are marginally safer in those walled gardens, which police their own ecosystem better than others," Sonne reiterated. He also acknowledged the efforts of some programmatic platforms, citing Comcast’s Beeswax as an example of a "tightly run" platform that prioritizes transparency and control.
However, for those venturing into the broader programmatic landscape, a strategic partnership with an experienced agency or a specialized firm like Daypart can be a prudent investment. "The safer bet is to work with an agency that knows what it’s doing and can stop fraudulent activity."
Reaching Out to Daypart

The firm’s website, Daypart.ai, provides further information on their offerings. Sonne is also accessible for professional engagement and insights via his presence on X (formerly Twitter) and LinkedIn, platforms where he actively shares his expertise and engages with the broader digital advertising community.
The ongoing evolution of digital advertising, coupled with the increasing sophistication of fraudulent schemes, necessitates a vigilant and informed approach from advertisers. By understanding the nuances of ad fraud, employing diligent verification methods, and knowing when to seek specialized expertise, businesses can better safeguard their ad spend and ensure their marketing efforts reach genuine audiences, driving meaningful engagement and tangible results. The shift from the expertise of a Facebook ad guru to a dedicated fraud hunter underscores the growing importance of combating these deceptive practices in maintaining the integrity and effectiveness of the digital advertising ecosystem.
