Ad fraud is a global problem of alarming scale – and it affects every campaign, including yours:
- 22% of global ad spend was lost to fraud in 2023
- That equals 172 billion dollars per year
- This number is expected to rise further by 2028
Fraudsters are becoming increasingly sophisticated. “Vapor,” one of the largest discovered ad fraud networks, consisted of over 300 malicious apps with 60 million downloads before being removed.
Fraud distorts campaign performance at multiple levels: Impressions on fraudulent inventory mean your ads are being served on fake websites. Automated clicks simulate interest that never existed. And a high proportion of bots among your website visitors distorts all your analyses – from bounce rate and conversion rate to A/B tests.
Not all bots are malicious. Many e-commerce sites see 60–80% bot traffic, most of which comes from legitimate sources such as search engines or monitoring services. The challenge is distinguishing between good bots, bad bots, and real users.
Here’s a controversial thought: the optimal fraud rate is greater than 0%. Why? Because fighting fraud consumes resources. Additional security measures slow down ad delivery, increase costs, and may limit reach. Beyond a certain point, the effort outweighs the benefit. The key is finding the right balance.
Server log analysis plays an important role here. Logfiles show exactly which user agents access your site, when, and how. Integrated marketing means connecting different data sources intelligently.
Your Action Plan:
- Raise awareness of ad fraud and its direct impact
- Plan campaigns carefully – inventory quality and price are closely linked
- Conduct short-term analyses, for example using server logs
- Work with specialised partners such as Integral Ad Science, DoubleVerify, or HUMAN
