Click Fraud: The silent drain on marketing budgets and how to combat it in 2025

If you don’t care about click fraud, do you even care about your ad budget?

As digital ad spending continues to grow, so does the invisible threat siphoning billions from marketing budgets...click fraud.

This malicious practice essentially involves illegitimate clicks on paid ads, often by bots, fraudsters, or even competitors, wasting resources and distorting campaign metrics.

For anyone working in marketing, responsible for an ad budget or just curious about growing fraud trends, understanding and combating click fraud is no longer optional; it’s essential for maintaining your ROI and marketing efficiency in 2025.

The scope of the problem

The scale of click fraud is staggering and shows no sign of slowing down 📈

Industry reports from Statista estimate that ad fraud, including click fraud, will cost businesses over $172 billion dollars globally by 2028.

It’s a problem that doesn’t just affect large enterprises; small and medium-sized businesses (SMBs) are equally vulnerable, often unaware that a significant portion of their ad spend yields no real return.

Think it only targets key sectors? Think again.

Sure, certain industries face heightened risks due to their reliance on digital advertising and high-value keywords, but click fraud shows no mercy or favouritism in the industries it affects.

What is click fraud?

Essentially, the term ‘click fraud’ refers to malicious or ‘invalid’ interactions with your online ads, without genuine intent or interaction with a view to deplete your ad budget, skew your performance analytics and ultimately, damage your advertising campaign's effectiveness.

This deceptive activity can be carried out by competitors (also referred to as ‘competitor clicks’), automated bots, or even malicious individuals, and it poses a significant threat to businesses relying on digital advertising for growth and visibility.

The real-world culprits behind click fraud

Click fraud isn’t a random occurrence; it’s typically driven by a combination of automated programs and deceptive practices.

Bots and web crawlers are at the forefront, acting as the primary tools for inflating clicks artificially. These programs mimic human behaviour, clicking on ads to generate revenue for fraudulent publishers or to drain competitors' ad budgets 🤖

It’s worth noting that not all bots and crawlers are inherently ‘bad’, with plenty of bots tasked with productive tasks to make our lives in business easier (just look at bots you can use in tools like Slack) or Google’s site crawler tasked with indexing the web, to make our searches more refined and informative.

Beyond bots, malicious actors also exploit poorly secured networks or hire "click farms," where real individuals are paid to click on ads repeatedly. Even legitimate-looking sites can sometimes host hidden click fraud operations, leveraging compromised devices or browser scripts to generate fraudulent traffic 🖱️

By understanding these culprits, it becomes clear why robust third-party detection and monitoring systems are crucial for protecting ad budgets and ensuring transparency in the digital advertising ecosystem.

Ask yourself, in your current online marketing activities, can you tell the difference between a bot and a genuine user? 🤷

The ever evolving tactics of click fraud in 2025

As fraud detection technology advances, it’s no surprise that simultaneously, as do the tactics deployed by fraudsters. The game of cat and mouse between advertisers and fraudsters means that cybercriminals are continuously developing new ways to evade detection and manipulate both ad networks and marketing budgets alike 🪤

The rise of the AI powered bot

In 2025, click fraud will be more sophisticated than ever, as we see an increase in fraudsters leveraging artificial intelligence to bypass traditional security measures. 

Whilst basic click fraud bots have existed for years now, modern fraudsters are now utilizing AI to drive bots capable of mimicking human-like behaviour and interactions like never before.

These bots can simulate real browsing patterns and behaviour, such as scrolling, completing form submissions and hovering over specific elements of a page, making it increasingly difficult for traditional fraud detection methods to distinguish between a real user and potentially malicious software.

Constantly evolving algorithms allow these bots to learn from real users by adapting both their page viewing behaviour and clicking habits to help them seamlessly blend in with legitimate traffic. Instead of generating high-frequency, repetitive clicks which are ultimately easier to detect, sophisticated bots can spread their actions over time, interacting sporadically with various parrots of a website and engaging with random content before clicking on an ad.

Ask yourself, in your current marketing activities, can you tell the difference between an AI driven bot, and that of genuine human interaction? 🤔

The abuse of residential proxies

The use of residential proxies and botnets is on the rise, with fraudsters attempting to obscure their identities and real locations. Instead of relying on a single IP address (which not only changes often, but can also be easily detected and blocked), they spread fraudulent clicks across many real devices without the owners' knowledge and permission.

These botnets can easily generate fake clicks from different locations, making it much harder to identify and ultimately stop the fraud.

Additionally, fraudsters use residential VPNs and proxy services to make their traffic look like it's coming from real users. This makes it extremely difficult for advertisers to tell the difference between what’s real and what’s fake. As a result, traditional methods like IP blocking are no longer enough to stop click fraud.

5 reasons why if you don’t care yet, you should

If you’re not yet protecting your business from click fraud, it’s time to start.

Here are the top 5 reasons why taking action now could make all the difference - and they just might pique your interest:

  1. Boost your campaign’s ROI: By eliminating fake, malicious or invalid clicks, you can ensure that your ad spend is targeting genuine leads and potential customers, significantly improving your return on investment (ROI) 💰
  2. Improve your data accuracy: Data drives decisions in business, so if your campaign performance is skewed by invalid clicks, how do you gauge the true effectiveness of your campaigns? Addressing click fraud helps to ensure cleaner data, for better decision making 📊
  3. Enhance your audience targeting: Removing fraudulent clicks helps to refine audience targeting by focusing only on genuine user behaviour and interactions, leading to more effective campaigns 🎯
  4. Prevent wasted ‘invalid’ clicks: Just as you wouldn’t hand out cash freely, why pay for clicks that deliberately drain your marketing budget? Addressing this issue ensures your resources are directed toward genuine opportunities, reducing unnecessary spend and ultimately prolonging the effectiveness of your campaigns 💸
  5. Protect your brand reputation: Fraudulent clicks can associate your brand with low-quality traffic sources. Proactively addressing this issue helps maintain a positive reputation in the digital advertising space 🛡️

Industry standards you need to know about

Understanding click fraud and how it occurs is one thing, but knowing how it can be detected and the types of varying industry solutions is another 💡

While built-in tools in PPC accounts like Google, Meta & Microsoft offer some level of protection, they often fall short of fully eradicating the issue entirely and where tactics continue to evolve, can you be sure they keep up with protecting your ad budget?

Lets face it, where your primary goal is to make revenue as an advertising platform, solving click fraud isn’t going to necessarily be task #1.

With the growing sophistication of fraudsters, advertisers need to employ a combination of methods to identify and mitigate these deceptive practices.

By leveraging a range of techniques, such as IP blocking, fingerprinting, and tracking user behaviour, alongside monitoring traffic sources and more, advertisers can adopt a comprehensive approach to combating click fraud.

These methods, including industry staples like device identification (also referred to as ‘device fingerprinting’), browser analysis, and location tracking, help identify suspicious patterns and ensure more accurate ad performance, often in real-time.Let’s take a closer look at what some third-party technical solutions include:

  • IP address analysis: The riskiest and most limited solution of them all. Whilst data points like IP addresses are useful to track, alone they aren’t enough to solve the problem of click fraud. IP addresses are constantly changing and PPC providers like Google and Meta often have highly restrictive limits on just how many IP’s you can block at any given time 🚫
  • VPN detection: Fraudsters often use Virtual Private Networks (VPNs) to mask their real location and avoid detection. Advanced detection methods can identify the use of VPNs, flagging clicks from unusual locations or regions where they wouldn't normally occur 📍
  • Device fingerprinting: Think of this a little like your own fingerprints, each unique to you. Now apply a unique ID to each of your devices that doesn’t change, even when evasion tactics are used and you’ve got device fingerprinting - one of the more technical and useful methods used to detect and block click fraud 🔍
  • Bot and crawler detection: Bots and automated crawlers can generate false clicks and quickly deplete your ad budget. By using machine learning algorithms and behavioural analysis, it’s possible to detect patterns of non-human activity, such as rapid click-through rates or inconsistent browsing behaviour 🤖
  • Click pattern analysis: This involves examining click behaviour over time, such as the frequency and timing of clicks, to identify irregular patterns. For example, clicks occurring at the same intervals or a high frequency in a short period can be flagged as potentially fraudulent - why use manual processes to analyse hundreds of clicks to spot patterns when automated solutions can do this in seconds 🖱️
  • Geo-fencing and location analysis: Analyzing the location of a click can be important for detecting fraud, especially when there are sudden spikes from regions that are typically not targeted by the ads or even in areas your ads should be showing. Geo-fencing can also be used to limit where clicks should originate, preventing fraudulent activity from outside the intended region 🌎
  • Referrer URL analysis: By tracking the referrer URL, advertisers can assess the source of traffic and verify whether it aligns with legitimate sources. Clicks originating from unusual or suspicious referrer domains can be flagged for further scrutiny ❓
  • Machine learning: What could take individuals hours to review and analyse clicks, takes ML seconds. Sure, both AI and machine learning often have suspicious glances cast their way, but in the case of click fraud software, they are the key to real-time detection and prevention ⌛

Selecting the right solution for the specific problem

When it comes to combating ad click fraud, one size definitely does not fit all.

The approach you’ll need to take will largely depend on the nature of your business, your specific goals, and the level of risk you're ultimately willing to tolerate - some businesses may only want to detect and manually monitor click fraud, whilst others may want a more comprehensive solution that can detect, analyse and block it outright ⛔

When selecting the right solution for your needs, consider how much time and effort you're willing to invest in preventing fraud. Whether you need a simple monitoring tool, a lightweight oversight system, or a fully automated, real-time fraud prevention service, make sure the solution aligns with both your business's goals and the scale of your advertising activities.
