What is Click Fraud & Why Should You Care?
Click fraud occurs when someone or something clicks on your ads without genuine interest in your business. These fraudulent clicks cost advertisers billions every year, and most don’t even realize they’re victims.
Common Types of Click Fraud:
1. Bot Traffic
- Automated programs generating fake clicks
- Data center traffic masquerading as real users
- Scraping tools clicking ads while harvesting data
2. Competitor Clicks
- Competitors deliberately clicking to waste your budget
- Systematic campaigns to drive up your costs
- Making your ads hit budget limits early
3. Click Farms
- Human workers paid to click ads
- Often from specific geographic regions
- Harder to detect than bot traffic
4. Accidental Fraud
- Publishers accidentally clicking their own ads
- Users repeatedly clicking without intent
- Mobile app misclicks
Why This Matters: Every dollar wasted on fraudulent clicks is a dollar not reaching real customers. In competitive industries, click fraud can destroy campaign profitability.
Google's Built-in Invalid Click Detection
Google does have an internal click fraud prevention system, but it’s not perfect. Here’s what you need to know:
How Google’s System Works:
- Real-time filtering – Identifies and removes obvious bot traffic
- Offline analysis – Reviews clicks for patterns after the fact
- Automatic credits – Refunds for detected invalid clicks
- IP blocking – Prevents known fraudulent sources
The Problem:
Studies show Google’s system catches only 60-70% of fraudulent clicks. That leaves 30-40% of fraud undetected, eating into your budget.
How to Check Your Invalid Click Rate (Step-by-Step)
Let me show you exactly how to find this data in your account:
Step 1: Access Your Campaign Data
- Log into Google Ads
- Navigate to your Campaigns tab
- Look for the “Columns” button
Step 2: Add Invalid Click Metrics
- Click “Columns” → “Modify columns”
- Search for “invalid” in the search box
- Add these metrics:
- Invalid clicks
- Invalid click rate
- Invalid interaction rate
Step 3: Analyze Your Data
Here’s what each metric means:
Red Flag Alert: If your invalid click rate exceeds 10%, you have a serious problem. I’ve seen search campaigns with rates under 5%, so anything above 10% requires immediate action.
Real Example from My Account:
- Total clicks: 260
- Invalid clicks: 57
- Invalid click rate: 18% ❌
This is too high! While Google caught these fraudulent clicks, it shows significant fraud attempts targeting the account.
Step 4: Check for Refunds
- Go to Tools & Settings → Billing → Billing summary
- Look for “Adjustments” line items
- These show Google’s automatic refunds for invalid clicks
