PPC click fraud: what it is and how to stop it
PPC click fraud drains paid search and social budgets through bots, farms, competitor abuse, and residual invalid traffic that still reaches your site.
Definition
What is PPC click fraud?
PPC click fraud is invalid or abusive activity on pay-per-click ads that generates billed clicks without real buying intent — including automated bots, click farms, competitor clicking, and residual low-quality traffic.
Platforms filter a share of it. Independent PPC fraud protection and click fraud detection focus on what still reaches your landings between network credit cycles.
Types
Common forms of PPC click fraud
Bot and automated clicks
Scripts and headless browsers generate paid sessions with no real intent.
Click farms
Low-paid or coordinated human clicking designed to burn budgets at scale.
Competitor abuse
Rivals repeatedly click high-CPC brand or category terms to raise costs.
Residual invalid traffic
Waste that still reaches landing pages after platform filters and credits.
Warning signs
How to recognize PPC click fraud
High clicks, low engagement
CPC and volume look fine while bounce rates spike and conversions stall.
Repeat IPs on expensive terms
Same sources hit brand or high-bid keywords many times with no leads.
Odd geos or hours
Traffic from regions or times you do not serve, without sales lift.
Sudden CPL or ROAS shifts
Cost per lead doubles or ROAS drops while creatives and offers stay the same.

High clicks with low engagement, repeat IPs on expensive keywords, odd geos or hours, and sudden CPL or ROAS changes without offer or creative shifts.
How do I stop PPC click fraud?
