Considering that ad fraud will cost marketers $ 172 billion by 2028, according to Statista Reports, tackling the fraud becomes crucial to safeguarding advertising investments.
The digital advertising space is continuously in flux, opening new avenues through which businesses can reach their target audiences. These opportunities also bear the ever-growing threat of ad fraud as one of the biggest challenges facing advertisers today.
Ad Fraud is omnipresent across Walled Gardens, direct buying platforms, affiliates, and programmatic channels. It brings a financial drain while weakening the efficiency of advertising campaigns.
AI-driven post-bid solutions must be deployed across campaigns to tackle this problem. They should be backed by ML algorithms and big data analytics. According to mFilterIt reports, average fraud is to the tune of 15-25% depending on the channel and tools help bring ROI efficiencies via automated active blacklisting.
What is Ad Fraud?
Ad fraud is any intentional activity designed to falsify digital advertising impressions, clicks, conversions, or data in general for revenues or metrics manipulation. This might be through bots, fake websites, malicious code, or other devious means. The motive behind such an action most often aims at making money off ad revenue by showing invalid traffic for ads or making the advertiser think the ad is being viewed by real people, which causes ad spend waste and inaccurate performance metrics. To prevent this, it’s helpful to understand how ad fraud works, and the tactics fraudsters rely on.
Types of Ad Fraud
It can be further divided into two key classes – General Invalid Traffic and Sophisticated Invalid Traffic. Both pose various problems for advertisers. Sophisticated fraud is identified with the funnel approach with a post-bid analysis.
General Invalid Traffic (GIVT)
This category includes simpler forms of fraud in advertising, often captured by general filtering.
- Blacklisted IP – Fraudsters make use of IP addresses found as sources of invalid traffic. Ad impressions and clicks served to such blacklisted IP addresses are counted as forged impressions and clicks depleting ad budgets.
- Geo Fraud – Ads are delivered outside targeted geographical areas, which means money is wasted on irrelevant audiences. This happens mainly in campaigns with tight regional targeting.
- VPN and Data Center Hosting (DCH) – The traffic usually comes from VPNs or data centers to mask its origin as though it were real. It is a means of creating fake ad traffic that seems to originate from real users but is fraudulent.
Sophisticated Invalid Traffic (SIVT)
SIVT has some of the more advanced kinds of ad fraud that are trickier to spot and generally require more specialized anti-ad fraud solution.
- Fake Attribution – This means fraudsters fudge conversion data to take credit for conversions or actions they had no hand in. It might mean the redirecting of real users through fraudulent paths to lay claim to an affiliate or ad revenue.
- Fake Clicks – This form of click fraud involves creating an impression of organic clicks on advertisements through automated bots or scripts without the involvement of real users with intent.
- Fake Devices – The fraudster uses device emulators or scripts to fake the user’s behavior of viewing and interacting with an ad, thus creating unreal impressions and interactions.
- Duplicate Users – Duplicate Users are those ads reporting metrics for the same user on different devices and or platforms at different times in digital advertising and analytics.
How Ad Fraud Works
To effectively protect against ad fraud, you must understand how it works. Ad fraud isn’t committed against a perfect weak link in the digital advertising ecosystem, but rather fraudsters find ways to game the system to create invalid traffic and deliberately mislead advertisers. Common techniques include:
- Bot Traffic – A bot is an automated program masquerading as human traffic. These can result in simulated clicks, views, or impressions. Bots can be very sophisticated, emulating the usage patterns of real users in such a way that simple filters cannot catch them.
- Ad Stacking –This is a tactic in which multiple ads are layered on top of each other inside one ad placement, where all a user sees is the top ad. This means that the advertisers will be charged for all the ads as if they had been viewed completely, creating huge financial waste.
- Pixel Stuffing – Ads are delivered in a very minute 1×1 pixel, invisible to the web users while the impression is registered in records. This is deceptive and inflates the number of impressions, feigning that ads are viewed.
- Domain Spoofing – It is essentially ad fraud in which the domain of an app or website is misrepresented as that of a more trustworthy or premium one than that of their own. This is done to deceive advertisers into believing that they are purchasing ads on credible mediums, while the actual ads are being served on unreliable or fake mediums.
- Low-quality Inventory – They are ad spaces that offer almost nothing beneficial to an advertiser. Such ad inventory includes placements on sites that have very little traffic, little to no genuine activity, and are intended purely to generate ad impressions or clicks deceitfully. These are called Made-for-Ad sites (MFAs).
Damaging Effects of Ad Fraud
There are various adverse effects caused by ad fraud towards advertisers and, to an extent, the entire digital advertising ecosystem.
Investment Loss
The business world may lose over $100 billion to ad fraud in 2024 alone. That’s a big chunk of marketing money that could be spent on reaching out to the very real public to drive real results and it affects the ROI.
Skewed Metrics
Fraudulent activities result in bloated performance metrics, such as impressions, clicks, and conversions. Assessment of real effectiveness in campaigns and implementing changes in strategy thereby becomes hard.
Lower Reach
Spends on fraudulent ads and fake clicks mean lesser budgets to reach real and quality audiences. The overall reach and impact of ad campaigns are lower this way.
Brand Safety Concerns
It is important to protect the brand’s reputation by preventing ads from appearing alongside inappropriate, harmful or misleading content.
How to Reduce Ad Fraud
Reducing ad fraud requires a mix of proactive steps, advanced technologies, and continuous monitoring. This includes a few of the best ways to reduce the impact of advertising fraud:
Focus more on Post-bid Fraud Detection rather than Post-bid Analysis
- In a pre-bid analysis or more simply put analysis done before the ad has been served, fraud detection is confined to just two elements, which are IP and User Agents. Also, the time for performing this analysis cannot extend over 10 milliseconds. As data shows, this results in a very modest 2% fraud identification.
- In this respect, post-bidding analysis proves superior to pre-bid impression validation since there are many more parameters available. With respect to their detection effectiveness parameters, it is done on deterministic, behavioral, and heuristic measures as well. Such a change in reasoning leads to higher detection of invalid traffic i.e. 15-25% approx.
- Leverage Advanced Ad Fraud Detection Tools – Advanced ad fraud detection tools use machine learning algorithms and artificial intelligence to identify the patterns that signify fraudulent activity. Such tools can analyze a great volume of data in real time, detecting anomalies and blocking fraudulent traffic. This allows for always-on channel and campaign optimizations.
- Optimizations through Automated Blacklisting – The tool which you choose should have automated blacklisting with integrations into the ad managers and include regular updates of fraudulent IP addresses, devices, and websites, while a whitelist maintains trusted sources.
Conclusion
Ad fraud is an evolving, dynamic threat that takes continued vigilance and proactive measures. By understanding the different forms of ad fraud, and their mechanisms by applying appropriate ad fraud detection software, businesses can also help defend investment in advertising, optimize campaign performance better, and maintain customer trust in digital marketing. By mitigating ad fraud, ensure your ads reach genuine audiences.
