First, fraudsters are getting smarter. There has been an increase of 28% in the more “sophisticated" kinds of fraud in Q1 2016. In particular, there has been a significant uptick in the hijacking of devices directly via Trojan Horses that use Doorway sites to generate fraudulent activity. This is a challenge in that that type of activity is difficult to detect. The good news, though, is that a greater focus and strong progress by platforms in addressing these challenges has been observed. This commitment, along with the efforts underway in the buy-side community, is essential in undermining the efforts of those who seek to destroy confidence in programmatic advertising. Pixalate congratulates all of the platforms in the GSTI for their proactivity and dedication to restoring trust in programmatic advertising. **About Pixalate’s Global Seller Trust Index (GSTI)** Pixalate’s monthly Global Seller Trust Index is the worldwide standard in programmatic advertising quality ratings.

Also per the MRC, “‘Invalid Traffic’ is defined generally as traffic that does not meet certain ad serving quality or completeness criteria, or otherwise does not represent legitimate ad traffic that should be included in measurement counts. Among the reasons why ad traffic may be deemed invalid is it is a result of non-human traffic (spiders, bots, etc.), or activity designed to produce fraudulent traffic.” ** ** *By clicking Download and entering your email address, you are agreeing to our [Terms of Use](https://www.pixalate.com/terms) and have read and acknowledge our [Privacy Policy](https://www.pixalate.com/hubfs/2024-08-20_Pixalate_Privacy_Policy.pdf). *Copyright © 2025 Pixalate** * * * * * * * * * * * * * * * * * * * * * * * * * * * * × ## Subscribe to the Pixalate Blog The first step in ad fraud prevention.
