We’re excited today to announce a significant upgrade to our free, publicly-available supply path database.
2019 has been a breakthrough year for programmatic supply path transparency, most notably through the rapid adoption of the IAB’s new sellers.json initiative. Sellers.json gives supply side technology companies a mechanism to provide greater transparency to buyers about the supply paths through which their bids reach publishers. It has been a major unlock to our supply path research and is already helping our clients refine their supply path optimization strategies.
We have been monitoring the adoption of sellers.json since June. Every day, our crawler checks for the presence of a file from over 150 supply side technology companies. As of today, we are successfully retrieving files from 66 companies (complete list below), and we continue to observe new files posted daily. A single integrated sellers.json table is now available to all users of our supply path database.
We are also announcing today a significant expansion of the scope of our original ads.txt crawler. Our crawler now successfully retrieves over 100,000 ads.txt files from both website owners and app developers. These website and app files are available to all users of our database through a single integrated ads.txt table.
We will continue to expand the scope of our ads.txt, app-ads.txt, and sellers.json data, and we will continue to publish this data as a free service to the industry. To request access to our free supply path database, click here.
