Ranking the most common types of Invalid Traffic (IVT) across Apple App Store app traffic in November 2025. See how High Risk Apps, Display Impression Fraud, App Spoofing, and other types of IVT impacted global open programmatic advertising traffic, as well as traffic in North America, EMEA, APAC, and LATAM.
This report ranks the most common types of IVT based on global data from November 2025. Rankings are determined by IVT Share of Voice (SOV, %), which measures each IVT type relative to total IVT rather than total impressions.
Pixalate’s data science team analyzed 25 billion open programmatic ad impressions worldwide to produce these insights. The findings are derived exclusively from Pixalate’s datasets, which consist primarily of buy-side open-auction programmatic traffic.
Pixalate identifies the country of traffic using IP address data and geolocation signals.
Per the Media Rating Council (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.” Where the traffic characteristics are suggestive of deliberate intent to mislead, such IVT is often referred to as “ad fraud.”
Also, 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.”
