Per the MRC, “'Fraud' is not intended to represent fraud as defined in various laws, statutes and ordinances or as conventionally used in U.S. Court or other legal proceedings, but rather a custom definition strictly for advertising measurement purposes. 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.
