Click fraud lawsuits: Key cases, legal challenges, and how to protect your business in 2025

Click fraud is a widespread problem in digital advertising. It occurs when a user knowingly and fraudulently clicks on a pay-per-click (PPC) online ad in an attempt to generate more revenue for the publisher or defraud the advertiser by increasing the ad’s cost.

The unethical process erodes online advertising integrity, costing businesses billions of dollars per year, and results in a growing number of lawsuits aimed at holding those involved accountable.

This article examines the nature of click fraud, its financial implications, key lawsuits, and legal implications, providing a comprehensive guide for businesses seeking to navigate this complex situation.

What is click fraud?

Click fraud involves the use of people, computer programs, or bots that click on PPC ads with no intention of buying the advertised product or service.

The aim is usually to deplete the advertiser’s budget or generate more revenue for publishers, who receive money for each click.

The financial impact of click fraud lawsuit

Click fraud is a significant drain on advertising budgets. Statista projects that global ad fraud losses, including click fraud, will reach $100 billion by 2025, up from $61 billion in 2022.

For a business spending $10,000 monthly on Google Ads, annual losses from click fraud can reach $12,000–$15,000.

Beyond wasted spend, it skews campaign analytics, making it harder to understand real customer behavior or optimize marketing strategies.

Forbes highlights that investing in fraud prevention protects ad budgets and ensures accurate data for decision-making.

The damage is especially severe for SMEs, which rely heavily on PPC ads but often lack the resources to detect and block fraudulent activity early.

Major click fraud lawsuits and their industry impact

The following are a few of the leading cases that serve to illustrate the scope and complexity of click fraud litigation.

1. The Google $90 Million settlement (2006)

In 2006, Google paid $90 million to settle a class action filed by Lane’s Gifts & Collectibles in Miller County, Arkansas.

The complainant claimed that Google had proven insufficient to guard advertisers against click fraud, both as an advertiser and an advertising network.

The settlement encompassed claims dating back to 2004, and Google needed to adopt more stringent mechanisms to identify and prevent click fraud.

The case highlighted the challenges advertisers face in proving they were defrauded and the use of expert witnesses, whose analysis, dating back to 2001, identified fraudulent programs facilitated by websites.

2. The Yahoo $4.5 Million Settlement (2005)

Yahoo paid USD 10 million and settled a class-action lawsuit in July 2005 that alleged that the company had not gone far enough in the fight against click fraud.

In the settlement, Yahoo paid $4.5 million in legal bills and refunded advertisers for any losses they had incurred since 2004.

This case has highlighted the responsibility of advertising networks in implementing an effective fraud-detection system and the financial consequences of negligence in this task.

3. Google Vs Auction Experts

Google successfully won yet another battle in an existing case when it approached Texas-based Auction Experts.

This publisher allegedly paid people to view ads on its website, resulting in a loss of $50,000 to advertisers.

This case also demonstrated that advertising networks, such as Google, might be plaintiffs in click fraud lawsuits, as they sought to defend their ecosystems and maintain advertisers’ loyalty.

4. The extortion attempt of Michael Anthony Bradley

In 2004, Michael Anthony Bradley, a resident of California.

He created software named Google Clique, claiming it could generate millions of invalid clicks to defraud Google.

In one intelligence case, Bradley attempted to extort Google out of the rights to the software by threatening to sell it to spammers unless Google paid him $100,000.

How to prepare for a click fraud legal case

Here’s a step-by-step guide to help you get ready:

1. Understand what constitutes click fraud legally

     a) Definition:

Click fraud occurs when online ads are clicked with malicious or fraudulent intent (e.g., by competitors, bots, or click farms), aiming to drain advertising budgets or skew analytics.

     b) Jurisdictional nuances:

Laws differ depending on the country. In the U.S., it may fall under computer fraud or wire fraud statutes; in the EU, it could involve digital fraud or unfair competition laws.

Key point: You have to prove intent and damage for most legal cases.

2. Gather and preserve all evidence:

Treat it like a digital crime scene:

     a) Click logs:

Export data from ad platforms (Google Ads, Meta Ads, etc.) showing timestamps, IP addresses, click sources, and device types.

     b) Analytics reports:

Keep Google Analytics, server logs, and any third-party fraud detection reports.

     c) Screenshots & videos:

Capture suspicious activity patterns or dashboards showing spikes in clicks without conversions.

     d) Correspondence:

Save emails with ad platforms, agencies, or anyone discussing the suspected fraud.

     e)Forensic reports:

If possible, get an independent click fraud detection service to issue a signed report.

Tip: Store backups in at least two secure locations. Once evidence is gone, it can be impossible to retrieve.

3. Engage the right professionals early

     a) Legal counsel:

Look for an attorney experienced in digital advertising law, cybercrime, or commercial litigation.

     b) Technical expert witnesses:

A digital forensic analyst or ad fraud specialist can help prove the fraud’s occurrence and quantify damages.

     c) Industry consultants:

They can provide testimony about industry norms and explain why the behaviour was abnormal.

4. Quantify the damages: Courts need numbers:

     a) Direct losses:

Cost of fraudulent clicks (advertising spend wasted).

     b) Indirect losses:

Include Lost sales, damaged campaign performance, and lower ROI.

     c) Reputational impact:

If your analytics were skewed, it could affect business decisions.

5. Document attempts to resolve the issue first:

Judges often want to see you try a resolution before litigation:

1. Record all communications with ad platforms (Google, Meta, Bing) about the fraud.
2. Keep case/ticket numbers from support chats or phone calls.
3. Note any refunds or credit offers.

6. Understand possible legal theories:

Your lawyer might pursue claims such as:

1. Breach of contract (if an ad platform or agency failed to provide agreed protections)
2. Fraud / Misrepresentation
3. Unjust enrichment
4. Computer Fraud and Abuse Act (in the U.S.) or equivalents elsewhere.

7. Prepare for cross-examination:

The other side may argue:

1. The clicks were legitimate but unqualified traffic.
2. Your ad targeting was too broad.
3. You cannot prove who committed the fraud.

8. Coordinate with Ad platforms:

Platforms may not always share all data, but your lawyer can request additional logs or records via subpoenas if necessary.

9. Keep a case rimeline:

Chronologically list:

1. When suspicious clicks began.
2. Actions you took to investigate.
3. Responses from platforms or suspects.
4. Impact on campaigns and business.

10. Plan your public relations angle:

If the case becomes public, you may want to control the narrative so it does not damage your brand.

Prepare a neutral, fact-based statement.

Working with lawyers and Ad platforms during disputes

Here’s a concise guide for working with lawyers and ad platforms during click fraud disputes:

1. With Lawyers

1. Choose the right lawyer: Look for one with experience in digital advertising, cybercrime, or commercial disputes.
2. Be organized: Give them a complete package of evidence (logs, screenshots, communications).
3. Stay clear and factual: Avoid assumptions; stick to verifiable data.
4. Follow their lead: Let them handle formal communications and legal strategy.

2. With Ad platforms

1. Document everything: Keep case numbers, email threads, and chat transcripts.
2. Be persistent but professional: Follow up regularly without emotional language.
3. Request specific data: IP logs, click timestamps, device info; if they refuse, note the refusal.
4. Escalate when needed: Ask for review by a senior team or account manager.

Legal challenges in click fraud lawsuits

There are several challenges facing advertisers and legal representatives when it comes to filing click fraud lawsuits.

Here are some of the significant challenges:

1. Defining and proving invalid clicks:

Invalid clicks are not reliably defined in a universally applicable way that allows for easy operationalization, except in obvious scenarios, making legal action challenging.

2. Proprietary sale:

Advertisers typically advertise through advertising networks such as Google or Bing, which in turn are less likely to offer detailed detection methods for fraud prevention, thereby hindering transparency and the collection of evidence.

3. Conflict of interest with Ad networks:

Advertising networks generate revenue on every click, regardless of its validity, and as such, raise concerns that networks will not take sufficient measures to prevent fraud.

4. Assigning liability:

Determining fault in cases of click fraud can be a challenging task.

For example, friends of the publisher can commit fraud without the publisher’s direct involvement.

However, advertisers may still want to hold them accountable, and the courts may disagree on who is liable.

5. Privacy of fraud detection:

Ad networks’ proprietary fraud detection systems have a privacy aspect, ensuring that the system is reasonable.

As the reports state, such as those posted by Tuzhilin, the only problems encountered are those that justify a case against ad networks on the grounds of a lack of transparency.

Strategies to prevent click fraud

There are some proactive measures that businesses can take to minimize the possibility of click fraud and preserve their advertising capital.

These are some of the effective strategies:

1. Apply fraud detection tools: ClickPatrol can monitor and block suspicious clicks in real-time.

The tool relies on machine learning to detect behaviours that indicate a likelihood of fraud, including instances of rapid clicks from the same IP address.

2. Check campaign analytics: Monitor click-through rates (CTR), conversion rates, and IP addresses regularly if they are alarming.

An unusually high volume of clicks, combined with a lack of conversions, may indicate potential fraud.

3. Geo-targeting and IP blocking: Target ad campaigns based on specific geographic areas and block IP addresses that appear suspicious to minimize exposure to fraud.

4. Collaborate with credible Ad networks: Partner with advertising networks that implement the strictest ad fraud prevention mechanisms and adhere to rigorous reporting and recording standards.

Protecting your business from click fraud lawsuits

Click fraud lawsuits are a crucial means of addressing the growing challenge of click fraud within the digital advertising sector.

At the same time, by being aware of the very essence of click fraud and applying powerful protection mechanisms, such as ClickPatrol, as well as being informed about relevant legal precedents, businesses will be more secure in the constantly evolving digital industry.
