Also per the *[*MRC*](https://mediaratingcouncil.org/sites/default/files/Standards/IVT%20Addendum%20Update%20062520.pdf)*, “‘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.”**.* [View full post](https://www.pixalate.com/blog/march-2025-brazil-publisher-trust-index-for-websites-and-mobile-apps) ```json { "@context" : "http://schema.org", "@type" : "BlogPosting", "author" : { "@type" : "Person", "name" : "Pixalate" }, "dateModified" : "2025-04-14T15:21:08.832Z", "datePublished" : "2025-04-08T18:00:00Z", "headline" : "Pixalate’s March 2025 Brazil Publisher Rankings for Websites and Mobile Apps: uol.com.br, ‘Sofascore’, ‘Space Shooter’ Among Top-Ranked For Open Programmatic Ad Traffic Quality", "image" : { "@type" : "ImageObject", "height" : 540, "url" : "https://2364596.fs1.hubspotusercontent-na1.net/hubfs/2364596/Blog%20Media/2025%20Covers%20and%20Images/Brazil%20-%20Publisher%20Trust%20Index%20-%20All%20-%20March%202025.png", "width" : 960 }, "mainEntityOfPage" : "https://www.pixalate.com/blog/march-2025-brazil-publisher-trust-index-for-websites-and-mobile-apps", "publisher" : { "@type" : "Organization", "logo" : { "@type" : "ImageObject", "height" : 60, "url" : "/hs/hsstatic/content_shared_assets/static-1.4092/img/default-amp-logo.png", "width" : 60 }, "name" : "Pixalate Blog" } } ```
