The Publisher Trust Index (PTI) reflects Pixalate’s opinions with respect to factors that Pixalate believes may be useful to the digital media industry. Our reports and indexes examine programmatic advertising activity on websites, mobile apps and Connected TV (CTV) apps. Any insights shared are grounded in Pixalate’s proprietary technology and analytics, which Pixalate is continuously evaluating and updating. Any references to outside sources in the Indexes and herein should not be construed as endorsements. Pixalate’s opinions are just that, opinions, which means that they are neither facts nor guarantees. This report is not intended to impugn the standing or reputation of any person, entity or app. 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.”.
