Automated clicking
Software generates impressions, clicks or downstream events that imitate advertising engagement.
Plain-language guide
What is click fraud?
Click fraud is intentional activity that creates advertising clicks without genuine customer interest, usually to waste an advertiser’s budget or generate publisher revenue.
Click fraud and invalid traffic are related, but not identical
Invalid traffic is the broader category. It can include malicious fraud, automated tools, duplicate interactions and accidental clicks. A visitor can also be real but poorly targeted, which is low-quality traffic rather than proven fraud.
Common examples
Intentional repeat clicks
A person repeatedly clicks an ad to increase costs or publisher earnings.
Manipulated interaction
Ad stacking, invisible placements or deceptive layouts create interactions users did not intend.
Warning signs that deserve investigation
- A sudden increase in clicks without sessions or conversions.
- Repeated click identifiers or sources within a short period.
- Traffic outside the selected market or business hours.
- One placement producing high volume and almost no engagement.
- Fake leads with patterned names, emails or phone numbers.
None of these signals proves fraud alone. Analytics measurement, consent tools, page performance and campaign settings can produce similar symptoms.
How advertisers can investigate
First inspect the invalid-traffic reporting inside the advertising platform. Then compare campaign cost with site sessions, server logs, click IDs and qualified conversion outcomes. Prioritize patterns connected to meaningful spend.
