Pixalate Releases November 2017 Seller Trust Indexes, Now Featuring Ads.txt Scores

Pixalate, Inc., the global leader in fraud protection and data intelligence, today released the November 2017 rankings in the Global Seller Trust (GSTI), Mobile Seller Trust (MSTI), and Video Seller Trust (VSTI) Indexes.

New this month: Ads.txt scoring

This month, Pixalate introduces ads.txt scoring to our GSTI to effectively measure the quality of a seller's network of domains that they represent. The industry-wide ads.txt effort was born in the IAB's Tech Lab and has created overnight transparency for buyers into the programmatic advertising ecosystem of sellers and domains.

As of December 18, 2017, Pixalate research shows that nearly half (45%) of the top 5000 domains which support programmatic have implemented ads.txt. That number has grown every week; it was below 10% in September.

Some of the world's leading buyers and sellers are pushing the programmatic ad-buying industry toward a world in which the use of ads.txt is ubiquitous in a bid to improve transparency, quality, and trust throughout the digital supply chain.

In choosing to rank sellers using their ads.txt presence as a metric, Pixalate recognizes that this new standard — already in use across more than 70,000 domains and 1.5 million sub-domains worldwide — is a critical component of seller trust.

November 2017 Seller Trust Index Highlights 

Below are some of the key takeaways regarding movers and shakers at the top of the rankings.

  • GSTI highlights: ONE by AOL captured the top spot in the U.S. in November. Sovrn was No. 2 again, while OpenX earned the No. 3 ranking. Google AdExchange increased to the No. 7 spot in the U.S. and was the No. 3 seller for international inventory. 
  • MSTI highlights: In November, AdColony was again the No. 1 seller on the MSTI, while ONE by AOL remained at No. 2. AppNexus, Rubicon Project, and Index Exchange round out the top five in this month's MSTI.
  • VSTI highlights: In the U.S., SpotX claimed the top spot, swapping places with Telaria (the No. 2). Teads was No. 6, while ONE by AOL was No. 9 — earning a top-10 spot in all three U.S. indexes this month (GSTI, MSTI, VSTI).
