PPC fraud has developed further than simple bot clicks. Fraudsters are now masquerading as humans. Bots have infiltrated everywhere and scroll, hover, and even type commands like humans. The invalid traffic might occupy between 25-30% of clicks, which costs 100 billion dollars annually, particularly in the high-CPC areas, such as legal and insurance. The top one is mobile and programmatic, with real-time bidding allowing bots to snipe auctions without being detected.

Historical trends indicate 19% of displays and 28% of apps are invalid, but 2026 introduces hyper-realistic humanoid bots developed using vast data. Are your rivals clicking on your adverts? Still huge. However, new entrants such as state-sponsored farms aim at enterprise budgets. Bad data is a cancer to your algorithms and results in bad bids and wasted scale.

As quantum computing advances, encryption cracking is imminent- fraudsters decrypt traffic to hit targeted attacks.
