If your campaigns are costing you more than they’re performing, it’s time to rebuild your strategy, because the issue might be lying in your traffic itself.

Ad fraud has become one of the biggest reasons impacting your campaigns and marketing budgets across walled gardens, open networks, affiliate platforms, apps, and programmatic ecosystems.

The first half of 2025 recorded an average global ad fraud rate of 39.7%, and fraud peaked at 49% in June, the highest in five years. With AI-driven bots, fake users, and manipulated attribution becoming more advanced, the financial impact is far deeper than most marketers realize.

A few years ago, a globally recognised brand cut two-thirds of its annual online advertising budget around $100 million. What happened next revealed a shocking truth about the digital advertising industry.  

There was little to no drop in performance. Conversions held steady, demand didn’t collapse, and the business continued as usual. The reason wasn’t efficiency; it was ad fraud and the brand that showed the mirror to the world was Uber. 

Fast forward to 2026, and the problem has only become more complex. 

If you are investing in paid media in 2026, it’s important to know that your PPC campaigns may already be exposed to highly sophisticated fraud tactics, many of them powered by advancements in AI. What once started as a side effect of digital advertising has now evolved into a deeply embedded part of the ecosystem marketers operate in today.
