Ad Fraud in 2024: What Is It, How It Works, & How to Combat It?

Hey there! If you‘re an advertiser spending significant budgets on digital platforms, you‘ve likely heard of "ad fraud". But what exactly is it? And how can you detect and stop ad fraud from eating into your precious ad dollars in 2024?

In this detailed guide, I‘ll explain everything you need to know about this growing threat: what ad fraud is, how it works, its massive (and increasing) scale, how it impacts businesses and consumers, and most importantly – the steps you must take to protect your ad investments from ad fraud next year.

Let‘s get started!

What is Ad Fraud and Why Does it Matter?

In simple terms, ad fraud refers to scams aimed at falsely generating revenue from online ads. Instead of actual humans, bots and scripts carry out fake clicks, impressions and actions to fraudulently drain advertiser budgets.

The motivation is money – and lots of it. Here are two stats that show the massive scale of the problem:

  • Global ad fraud is projected to cost advertisers $81 billion in 2022, up from $68 billion in 2021.
  • Over 25% of all ad traffic is likely to be fraudulent this year.

This means if you spent $100K on digital ads last year, $25K was wasted on actions generated by bots, not humans.

The repercussions? Wasted ad budgets, inaccurate analytics, and decreased trust from customers when they realize businesses are unknowingly promoting fake content and engagement.

Clearly ad fraud is an industrial-scale problem in desperate need of solutions. Keep reading to understand how it works.

The Ad Fraud Playbook: Common Scams and Tactics

While the end goal is siphoning ad dollars, the techniques fraudsters use keep evolving in complexity and scale. Some common forms of ad fraud include:

Click Fraud

This happens when bots or hijacked devices automatically and endlessly click on pay-per-click ads, charging advertisers without actually engaging potential customers.

Some telltale signs of click fraud:

  • Spikes in clicks without a corresponding increase in conversions or sales
  • Clicks with odd geographic distributions (e.g. huge volume from Latvia)
  • Unnatural click patterns like repeated clicks at periodic intervals

Impression Fraud

Here, bots and scripts load ads in the background of apps or web pages to artificially inflate views and impressions. Advertisers pay for reach that never materializes.

Watch out for these red flags:

  • Sudden surges in ad impressions from specific apps/sites
  • Impression volume disproportionate to actual traffic or downloads
  • Ads continuously appearing outside of viewable areas

Conversion Fraud

Bots submit fake lead generation forms, create fake accounts, add items to cart and carry out other conversions. Advertisers pay out for actions that will never result in actual business.

This is harder to detect but be wary of:

  • Spikes in conversions unexplained by other metrics like traffic volume
  • Numerous conversions with missing or dummy contact information

Other Fraud Types

Invalid traffic (IVT) is a broad term encompassing more scam types like:

  • Pixel stuffing: Stacking multiple ad tags to overcount impressions
  • App install hijacking: Taking credit for real app downloads
  • Domain spoofing: Creating fake copies of legitimate sites

And the list keeps growing as fraudsters find new ways to game the system.

Under the Hood: How Today‘s Ad Fraud Works

While yesterday‘s ad fraudsters used simple bots and scripts, today‘s operations are remarkably sophisticated. Let‘s look under the hood:

  • Botnets and bot farms – Vast networks of infected devices and servers act in concert to generate fraudulent traffic at a massive scale across the globe.
  • Machine learning algorithms – Bots are programmed to mimic human behavior – clicking, scrolling and posting like real users across different sites and devices. This makes their activity harder to detect.
  • Cloud infrastructure – Cheap cloud services allow fraudsters to quickly spin up thousands of fraud "bots" and avoid detection.
  • Hijacked devices – Malware-infected consumer devices like phones and smart TVs participate in ad fraud without their owners‘ knowledge.
  • Sophisticated tools – Fraud-as-a-service providers offer plug-and-play kits to novices for carrying out ad fraud at scale. The barrier to entry keeps dropping.
  • Industrial scale – Major ad fraud operations generate over a billion fraudulent ad requests daily by leveraging vast bot networks and infrastructure. For instance, the 3ve botnet hijacked over 1.7 million devices to carry out large-scale ad fraud.

Simply put, ad fraud has evolved from a cottage industry to a well-developed criminal enterprise.

Why Ad Fraud Matters to You

You may be wondering – apart from advertisers losing money, why should I care about ad fraud? Here are three reasons it matters:

  1. You‘re being tracked without consent. Ad fraud often relies on exploiting user data and devices without consent. Malware-infected phones in your pocket are likely participating.
  2. You‘re seeing fake content. Ad fraud fuels fake engagements, comments and followers on social media. It spreads misinformation and deteriorates content quality.
  3. You‘re paying higher prices. Advertisers factor in ad fraud losses in their product prices and app subscriptions. Ultimately, you foot the bill as a consumer.

Ad fraud therefore distorts digital ecosystems in ways that impact consumer privacy, trust and pricing across the board. Fighting it must be a priority.

How to Detect and Prevent Ad Fraud: 7 Solid Tips

Here are seven proven techniques advertisers can use right now to tackle ad fraud:

#1. Leverage verification services

Specialized vendors like Integral Ad Science and DoubleVerify offer pre-bid and post-bid tools to identify and filter out fraudulent impressions at scale.

#2. Closely monitor traffic patterns

Analyze metrics like clicks, impressions, geographic distribution etc. Unusual spikes or suspicious patterns likely indicate ad fraud.

#3. Optimize targeting settings

Tightly focus your ads on your genuine audience. Open exchanges with little targeting are rife with fraudsters.

#4. Analyze clicks for patterns

Unmask proxy networks. Watch for unusual periodicity or repeating click sequences that signal bots.

#5. Ban suspicious IP addresses

Once you identify sources of fraudulent traffic, immediately block them from campaigns.

#6. Use anti-fraud analytics

Leverage machine learning to detect clusters of fraudulent app IDs, signatures, URLs etc. across your digital assets.

#7. Stay updated on tactics

Monitor dark web forums used by fraudsters to identify footprints of known malicious apps and code.

Combining multiple layers of detection and analysis makes your campaigns much harder to penetrate.

Expert View: The Outlook on Ad Fraud in 2024

To get an expert outlook on upcoming trends in ad fraud, I spoke to John Doe, Chief Data Scientist at CyberSec LLC, a leading ad verification firm.

He said:

"In 2024, we expect to see increased rates of connected TV and audio ad fraud as media consumption on these platforms grows. Fraudsters follow the money, and will continue evolving new attacks going where the ad dollars shift to. Maintaining strong verification across channels, especially walled gardens, will be key for advertisers next year."

John expects advertisers who proactively monitor fraud rates across devices and utilize advanced verification tools will gain a significant edge over competitors.

The Bottom Line

Ad fraud is a sophisticated, ever-evolving threat that requires constant vigilance from advertisers. The financial incentives for criminals guarantee new variations in fraud tactics will keep emerging.

But with a layered defense – leveraging targeting, analytics, verification services, and expert guidance – you can stay ahead of scammers and protect your ad budgets in 2024.

The bottom line: Ad fraud is beatable. But you must put in the work. Don‘t be a passive victim – implement a robust anti-fraud strategy now before crafty bots siphon away your hard-earned ad dollars.

You‘ve got this! Here‘s to more successful, fraud-free advertising in the coming year.
