How to Protect Your Google Ads from Fraud Using Smarter Detection Tools

Click fraud is one of the most persistent threats to PPC performance. It wastes budget, distorts your metrics and feeds invalid traffic sources that never convert. In Google Ads, these fraudulent clicks are harder to spot than most advertisers realise. By the time you notice, the damage is already done.

Smarter detection tools are essential; they identify and block threats before they impact your campaigns. This blog breaks down why click fraud happens, why Google’s default protections fall short, and the advanced steps you can take to protect your spend.

Why Google Ads Click Fraud Is Harder to Spot Than You Think

Click fraud occurs when ads are clicked without genuine interest, often from bots, competitors, click farms or even returning users who repeatedly navigate to your site via paid ads rather than direct URLs. These behaviours inflate CPCs and corrupt performance data.

TrafficGuard’s Invalid Traffic analysis shows that click fraud rates in search campaigns typically range between 14% and 22%. That means nearly a quarter of clicks might be invalid; an alarmingly high leakage of budget. For practical illustrations of how this happens in real campaigns, read Examples of Click Fraud in Display Advertising.

Why Google’s Default Protections Aren’t Enough

Google’s built-in filters are designed to detect general invalid traffic, such as duplicate clicks or obvious bot activity. However, they are not equipped to catch more sophisticated tactics such as rotating IPs, device spoofing or behaviour masking. In addition, Google does not classify certain types of waste, for example hyper-engaged users clicking repeatedly without converting or loyal customers using branded ads to log in, as invalid traffic. Without dedicated click fraud prevention software,  you end up paying for both sophisticated fraud and non-incremental clicks that add no real value.

According to Statista, global ad fraud losses are projected to exceed 172 billion US dollars annually by 2028, with much of the growth driven by increasingly sophisticated schemes in programmatic advertising. This underlines why platform filters alone are insufficient for serious budget protection.

5 Advanced Ways to Protect Your Google Ads From Click Fraud

1. Segment traffic by device, location and behaviour

Fraud often clusters in specific devices, geographies or time zones. Segmenting your data early helps isolate anomalies. For signs to watch for, see 5 Metrics to Monitor in Performance Max That Might Signal Click Fraud.

2. Monitor unusual click patterns

Track spikes in clicks without corresponding conversions or odd session durations — red flags that indicate bots or coordinated click attacks.

3. Use click-level analytics

Aggregate metrics mask bad actors. Click-level visibility lets you trace every interaction to its true source with timestamps and patterns. If you’re unsure where to start, our Click Fraud Response Plan outlines a clear, actionable process.

4. Automate exclusions and rules

Reactive exclusions are too slow. Automate rules to block repeat offenders and suspicious sources as soon as they appear.

5. Use real-time blocking tools

Pre-emptive fraud prevention limits wasted spend before it happens. Tools like TrafficGuard’s Google Ads Protection block invalid clicks as they occur, giving you confidence in every dollar spent.
