2026 Guide: Stop click fraud by competitors with real-time IP blocking & monitoring

Prevent competitors’ click fraud by recognizing how much it drains your ad budget long before you notice.

In today’s high-stakes digital advertising landscape, a single rival repeatedly clicking your ads can wipe out your PPC spend within minutes.

With ad spend now over $1.16 trillion, malicious competitor clicks, bots, and click farms pose a serious threat to ROI.

The good news? A strong competitive ad-monitoring strategy can spot suspicious patterns early and protect your budget before real damage occurs.

This article will break down the issue, discuss the trends that have emerged, and demonstrate how to stop competitors’ click fraud so your ad spend can contribute to growth, not revenge.

What is competitor click fraud in 2025?

Fundamentally, click fraud is a covert waste of ad spend. Some fraudulent clicks are planned, rather than accidental or automated, to waste PPC budgets and cripple competition.

The competition (or contracted party) repeatedly clicks on your ads, which causes the ad platform to charge, but never converts, never purchases, and creates no real value.

Why is this a risk?

Fraudulent clicks are increasingly common, with Pixalate reporting 23% of desktop web ad clicks and 19% across all channels as invalid in 2024.

High-CPC industries like finance, real estate, and legal services are hit hardest: 20–25% fraud on a $10,000 monthly PPC budget leaves only $7,500–$8,000 for real traffic.

Beyond wasted spend, fraud skews analytics, misguides bidding algorithms, and can raise CPC over time. Smaller advertisers are especially vulnerable, as even a few fraudulent clicks can drain a significant portion of their budget.

Proactive monitoring and blocking of invalid clicks is essential to protect budgets, restore data integrity, and maintain a competitive edge.

How competitors drain your PPC budget: The hidden mechanics

The landscape is changing rapidly. Key trends marketers must know:

Fraud is growing, not shrinking

Major industry research shows ad fraud remains a huge and growing drag on budgets, with recent analyses putting global ad fraud losses in the tens of billions annually and rising further if defense strategies are not adopted.

Bots are becoming increasingly sophisticated and common

Bad bots have become stealthier and now account for a sizable share of overall traffic. Imperva’s findings that bad bots account for a substantial share of all traffic underscore that automated attacks have become a mainstream menace for advertisers.

Platforms are under scrutiny, but incentives conflict with one another

Investigative reporting has revealed that some platforms can tolerate high volumes of scam-related ads because ad revenue remains a priority, which complicates marketplace cleanup. This is underlined by the fact that advertisers cannot rely on platform policing alone.

Fraudsters are moving to API and mobile vectors

According to reports, there’s a growing share of sophisticated bot traffic targeting APIs and mobile channels, where programmatic ads and app installs are served. For this reason, fraud prevention needs to cover APIs and mobile telemetry too, not just the web.

Attackers mask their activity within the “normal” cadence of campaign performance

Academic and industry research underscores a tactic in which fraud is smoothed across campaign periods, with less fraud on high-traffic days and more on low-traffic days, making anomalous detection more difficult.

How to prevent click fraud by competitors (Actionable 2025 framework)

The combination of policy, platform controls, and third-party detection provides the best opportunity to prevent competitor sabotage.

Configure platform-level exclusions

• Use IP exclusions where you’ve identified abusive ranges.
• Restrict geographic targeting tightly to your markets.
• Use time-of-day restrictions when attacks are concentrated.

Utilize behavior-based detection

Track click-to-conversion time, session depth, and repeated patterns. Automated solutions that analyze behaviour in real-time will flag suspicious sessions before you waste more budget.

According to research, fraudsters make sure to blend their activity to appear human, and behaviour analysis is the defence.

Block known abusive IPs & residential proxy ranges

Aggressive IP and proxy blocking remove sources competitors use to “farm” clicks. Residential proxies enable fraudsters to look like normal home users; blocking these when suspicious reduces spoofed clicks.

Server-side logs plus cross-system correlation

Cross-check ad platform logs against server logs, CRM events, and analytics. If clicks are not resulting in downstream activity, consider them suspect.

Implement real-time click protection

Real-time defenders can identify and block invalid clicks before they’re charged or swiftly issue automated exclusions.

This is important to prevent competitors’ click fraud by enabling rapid bursts to take your ads offline.

Document and Escalate

Document suspicious IPs, times, and patterns. In cases where the behavior is clearly malicious and persistent, file formal complaints with the ad platform and attach logs; this helps firm up dispute resolution.
