How to report click fraud to Google in 2026: A step-by-step guide to protect your Ad budget

As digital advertising evolves in 2026, click fraud remains a persistent threat to marketers, especially for those running Google Ads campaigns. Fraudulent clicks—intentional, non-genuine interactions with ads—can drain your budget, distort performance metrics, and negatively impact ROI. Knowing how to detect, document, and report click fraud to Google is crucial for protecting your campaigns.

This guide provides a step-by-step walkthrough for reporting click fraud, using modern tools and strategies to safeguard your ad spend.

What Is Click Fraud?

Click fraud occurs when malicious actors, competitors, or automated bots click on your paid ads with no intention of converting. Common forms include:

• Competitor Clicks: Rivals deplete your ad budget intentionally.

• Bot Traffic: Automated scripts mimic human clicks to generate fake impressions.

• Affiliate Fraud: Partners click their own ads to earn commissions without delivering real traffic.

• Click Farms: Groups of people repeatedly click on ads to manipulate campaign metrics.

The impact of click fraud can be substantial, leading to lost revenue, inflated CPC, and misleading analytics.

Signs of Click Fraud in Your Campaigns

Before reporting to Google, confirm suspicious activity by looking for:

1. High Click-Through Rate (CTR) with Low Conversions
   An unusually high number of clicks without corresponding conversions often indicates fraud.

2. Repeated Clicks from the Same IP or Region
   Multiple interactions from identical IPs, ranges, or unexpected geographies signal non-genuine traffic.

3. Short Session Duration
   Users who click and immediately leave your site may be bots or fraudulent actors.

4. Spikes in Click Volume
   Sudden surges in clicks without an increase in marketing activity can indicate automated fraud.

5. Device or Browser Patterns
   Multiple clicks from the same device, browser, or fingerprint can reveal click farming.

Step 1: Gather Evidence

Before contacting Google, collect detailed records of suspicious activity:

• Campaign ID and Ad ID

• Date and time of suspicious clicks

• IP addresses and geographic location

• Click frequency and patterns

• Conversion data (or lack thereof)

Tip: Export click and conversion data directly from Google Ads and your analytics platform for accuracy.

Step 2: Use Google Ads’ Invalid Clicks Detection

Google Ads has built-in systems for detecting invalid clicks, but manual review may be necessary:

1. Navigate to Google Ads → Campaigns → Ads & Extensions.

2. Check metrics labeled “Invalid Clicks” or “Invalid Click Rate”.

3. Download the invalid clicks report for documentation.

This data provides a foundation for reporting suspected click fraud to Google.

Step 3: Report Click Fraud Using Google Ads Help

Google provides official channels for reporting click fraud:

1. Go to the Google Ads Help Center: https://support.google.com/google-ads/

2. Navigate to “Report Invalid Click Activity”.

3. Provide required details:

   • Campaign and Ad ID

   • Timeframe of suspicious activity

   • Number of suspected fraudulent clicks

   • Supporting evidence (IP logs, analytics reports)

4. Submit the report and track the case number for follow-up.

Tip: Be thorough and precise; Google requires credible evidence to investigate and issue refunds.

Step 4: Leverage Google Ads API or Click Fraud Detection Tools

For high-volume campaigns or enterprise-level accounts:

• Use the Google Ads API to extract click-level data programmatically.

• Integrate with click fraud monitoring platforms like clckfraud.com for real-time detection.

• Automated tools can flag suspicious clicks immediately, reducing financial impact.

Step 5: Request Credits for Invalid Clicks

After Google verifies fraudulent activity:

1. Google may adjust your account balance for invalid clicks.

2. Ensure your billing history reflects adjustments.

3. Continue monitoring campaigns to prevent recurrence.

Step 6: Implement Preventive Measures

1. IP and Location Exclusions
   Block IPs, ranges, or countries generating suspicious traffic.

2. Click Frequency Limits
   Set thresholds to prevent repeated clicks from the same user within a defined time.

3. Device & Browser Filters
   Exclude traffic patterns commonly associated with bots.

4. Affiliate Program Audits
   If affiliates drive traffic, regularly audit their sources to prevent internal fraud.

5. Real-Time Monitoring
   Use AI-driven fraud detection tools to proactively prevent click fraud before it impacts your budget.
