The report is an analysis of open programmatic advertising sellers highlighting the highest and lowest aggregates of web MFA Traffic. The report includes top sellers by estimated MFA ad spend, sellers’ MFA market share of voice (SOV), and the top ad platforms (SSPs) selling ads on MFA websites. MFA websites and apps can feature intrusive advertising techniques like pop-up ads, auto-play videos, or ads restricting access to content, often resulting in a poor advertising-to-attention ratio. Pixalate's data science team analyzed over 300 million open programmatic ad impressions globally from May 2024 to compile this research. ## **Key Stats: Pixalate’s May 2024 Web MFA Risk Analysis: Open Programmatic Sellers Report** - **Google Ad Exchange (72%)** was the No. 1 open programmatic seller most used by sites flagged as MFA, according to Pixalate’s data - **Bright Mountain Media **sold ads on the fewest amount of sites flagged as MFA (under 1%) - **Google AdExchange **had the largest increase in MFA ad spend SOV **(7%; up from 4% in April 2024)** of estimated open programmatic ad spend on websites flagged as MFA - **Bright Mountain Media **and **Opera Ads** held the smallest MFA ad spend SOV (less than 1%) of estimated open programmatic ad spend on sites flagged as MFA ## **Open Programmatic Sellers Most Used By Sites Flagged as MFA*** 1. Google AdExchange sold ads on 72% of sites flagged as MFA, as measured by Pixalate (up from 67% in April 2024) 2. Magnite - 33% (down from 50% in April 2024) 3. Xandr Monetize - 31% (down from 45% in April 2024) 4. Sharethrough - 28% (down from 43% in April 2024) 5. Equativ - 25% (down from 36% in April)  ***Share of MFA websites with impressions sold by the given seller as of May 2024; as measured by Pixalate** ## **Open Programmatic Sellers by Highest Estimated MFA Ad Spend* on Sites Flagged as MFA*** 1. Magnite sold 18% of all ad spend on sites flagged as MFA in May, as measured by Pixalate (up from 17% in April 2024) 2. PubMatic - 12% (down from 13% in April) 3. Equativ - 9% (down from 10% in April) 4. Index Exchange - 8%  (unchanged from April 2024) 5.

Pixalate employs a multi-signal analysis approach to identify websites with traffic patterns exceeding established baselines, which are calculated by analyzing website impression quantiles across the entire dataset.  Websites exceeding these baselines in one or more factors are flagged as potential MFA sites.

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.
