Interestingly, Anchor found that malicious, “attempted” click fraud had fallen off in this period—dropping from 22.9% of all clicks in Q2 to only 18.6% of all clicks in Q3. Accidental, “innocuous” click fraud rose slightly (0.4 percentage points) to 4.6%. (Anchor measure all attempts at click fraud, not just charged clicks.

What do you think? Is Click Forensics’ more pessimistic report right, or does Anchor Networks more accurately reflect the state of the industry?
