Ad Quality Monthly Report-April 2018

Blog Post created by karl.moats on May 10, 2018

At PubMatic, we understand the risks associated with poor ad quality and are committed to keeping you safe. We have a team who believes very strongly that a clean ecosystem benefits everyone, and we take a vigorous approach to eliminating ad fraud. We pioneer the latest tools, services partnerships and standards available in the marketplace to root out ad fraud.


We wanted to give you a deeper view into a few ways how we have been doing our part in April 2018: 


TAG Certification 

PubMatic is pleased to announce we have been accredited with the Trustworthy Accountability Group (TAG) “Certified Against Fraud” seal in April 2018. The seal recognizes our ongoing dedication to “combatting fraudulent non–human traffic in the digital advertising supply chain.”


TAG is a global certification program leader in rooting out criminal activities and restoring faith in the digital advertising industry. Forged through top trade organizations, TAG is committed to eliminating fraudulent traffic, combating malicious creative, preventing Internet piracy and promoting greater transparency in digital advertising.

“We are delighted to recognize PubMatic with TAG’s Certified Against Fraud Seal, demonstrating its leadership in adopting TAG’s rigorous standards in fighting non-human traffic,” said Mike Zaneis, CEO of TAG. “We look forward to continuing to work with PubMatic to raise the bar for the digital ad industry in fighting fraud and other criminal activities that damage the supply chain.”  

In addition to our recent TAG certification, we are actively fueling advertising innovation by exceeding industry standards. Our mission is to provide a transparent and brand-safe marketplace for not only our partners but the ad tech ecosystem, as a whole.



PubMatic’s Real-Time Ad Scanning (RTAS) suite of tools applies both proprietary and third-party technology to provide protection for desktop, mobile, and video ads while addressing quality and security issues. Our ad scanning technology can screen every ad in the bid stream and make automated judgments on thousands of creatives every day spanning thousands of advertisers, immediately spotting and blocking contentious creatives at the source.


RTAS dives much deeper to root out malicious creatives and IBVs that publishers would have otherwise missed:


  • RTAS caught and automatically blocked 51,769 malicious creatives and 320,004 IBVs in April 2018. 
  • By comparison, RTAS caught and automatically blocked 65,087 malicious creatives and 175,279 IBVs the previous month.



Ad fraudsters are wily in their ways, coming up with new malicious creatives each and every day. Thankfully, RTAS stays one step ahead in monitoring the latest trends in ad fraud. Data below exposes malicious creatives patterns over the past three months:

PubMatic scanned roughly 18 million creatives from February through April 2018, however, the number of new malicious creatives has more than halved from February (92,352) to April (40,455). 

While ad fraudsters have devised fewer new malicious creatives in recent weeks, PubMatic does not take any chances. PubMatic identifies these creatives before they are ever served, and blocks them across our publisher base, should they come through again.


In sum, PubMatic has a zero tolerance policy towards fraud on our platform. We protect our customers’ trust by maintaining a clean platform with the highest ad quality and brand safety standards.
