From Video Partners to Search, fraud exposure is anything but uniform. Discover where invalid clicks tend to spike and how you can transition your efforts toward traffic with higher intent.
I’ve always considered Google Ads as the it-place for ad spending when stacked against social platforms. Yet, the sheer scale doesn’t make it bulletproof. Click fraud is a stubborn adversary, threatening the efficiency of our budgets based on ad placement.
Google Ads provide a vast reach, but not all campaigns face equal risks. Some are more vulnerable to malicious activities. To safeguard our margins, grasping what constitutes click fraud, its origins, and shielding our campaigns is essential.
What are invalid clicks?
Invalid clicks are false interactions lacking genuine consumer intent. They’re not driven by real human interest; thus, they skew performance data and drain budgets without potential for conversion. They mainly arise from these sources:
- Botnets: Hijacked devices under a “botmaster” generate immense automated traffic mirroring human behavior to inflate metrics or initiate DDoS attacks.
- Click farms: Low-paid workers or scripts manually clicking ads create a façade of engagement, misleading brands on campaign effectiveness.
- Ad injection and malware: Malicious software injects unauthorized ads or forcibly redirects users, hijacking legitimate revenue and eroding trust.
- Pixel stuffing and ad stacking: Ads served but unseen. Pixel stuffing compresses ads into invisible pixels; stacking layers ads in one slot, resulting in paid impressions without exposure.

The rising trend of fraud
Fraud Blocker recently determined the average invalid click rate across Google Ads at 11.4%, and it keeps growing.
To illustrate, in 2010, the rate was 5.9%, jumping to 12.3% by 2024. This doubling points to AI-powered bots and malware that skillfully bypass basic security.

Invalid click rates fluctuate depending on campaign setup, driven by:

- Industry competition: High CPC fields like legal and insurance are prime targets for adversaries exhausting budgets through clicks.
- Targeting parameters: Broader keywords or regions high in bot activity can flood “junk” traffic.
- Refinement tools: Negative keywords and audience exclusions form a barrier against unwanted clicks.
Campaign hierarchy: Which are the biggest violators?
Risk levels vary significantly across Google Ads inventory. Here’s how different campaign types rank in exposure:
The biggest risk: Google Video Partners
- Invalid traffic in Video Partners is notably high, extending beyond YouTube to third-party sites.
- Many sites provide little control, resulting in views from bots or insignificant placements.
Display campaigns: Highly vulnerable
- Display ads often face low-quality or AI-created sites.
- Sometimes, over half the clicks on a site prove invalid.
- Major publishers are more secure, but there’s variability in network risk.
Shopping and Demand Gen: The automation tax
- Automation leads to clicks from price-tools and bots.
- These clicks, although not always malicious, distort optimization data.
- Spreads risk across Google’s ecosystem.
- Identifying traffic sources is challenging, leading to unnoticed invalid clicks.
Search: The safest bet

- Search campaigns are most secure.
- Simulating genuine search behavior is difficult for bots.
- Yet, even in safe realms, a 2% fraud rate can hurt financially, especially in high CPC arenas.
How to mitigate the risks
In helping clients across various industries, identifying fraud onset patterns tailored to sectors remains vital. Our approach is proactive. Shifting from broad settings to a focused, high-intent strategy is key.
Here’s a table highlighting patterns we monitor to curtail invalid click rates:
| Factor | Higher risk (Aggressive) | Lower risk (Strict) |
| Location | Global or “Presence or Interest” | “Presence Only” (User is physically there) |
| Keywords | Broad match / Generic terms | Exact match / Long-tail phrases |
| Networks | Including “Search Partners” and “Display” | Google Search Network only |
| Exclusions | No negative keywords or placement lists | Robust negative lists and app exclusions |
| Scheduling | 24/7 (Bots often spike at night) | Custom schedules aligned with business hours |
To cut down fraud exposure effectively, here’s what we can do:
- Audit placement data: Regularly review ad placements to exclude sites or apps with high click rate but low conversion.
- Limit AI Max reliance: While automation offers power, a “set and forget” approach invites wasted spend. Maintain manual oversight.
- Review refunds: Google may refund for detected fraud, but subtle cases can slip through. Compare internally logged data with Google’s to find inconsistencies.
