TAG Publisher Sourcing Disclosure


CBS Interactive Inc. (“CBSi”) is a participant in the Trustworthy Accountability Group (“TAG”) Certified Against Fraud Program and is “Certified Against Fraud” due, in part, to CBSi’s commitment to the promotion of transparency in the advertising marketplace. As part of that ongoing commitment to transparency, CBSi will be disclosing certain information related to the use of what TAG defines as “Paid Traffic Sources” (provided below) by CBSi in connection with the CBSi properties — including, at minimum, the overall percentage of “Visits” (as defined by TAG and provided below) in the most recent calendar quarter that were from Paid Traffic Sources. This Description of Methodology (including all related information and data as may be updated from time to time) is intended for buyers or prospective buyers of advertising on the CBSi properties and is provided “as-is” and without obligation or warranties of any kind. Nothing in this Description of Methodology shall grant any party any rights or privileges in connection with any purchase or agreement to purchase advertising on the CBSi properties nor confer any obligations or commitments on the part of CBSi to any party related to the information and/or data disclosed in this Description of Methodology. While the disclosures in this Description of Methodology are made in good faith, CBSi shall not be responsible or liable to any party for any inaccuracies resulting from or related to the unavailability or incompleteness of relevant data, or an error, fault, and/or unknowing/unintentional omissions on the part of CBSi or a third party providing CBSi with such information.

TAG defines a “Visit” to be the “activities from a uniquely identified client that ends when there are 30 consecutive minutes of inactivity between the client and the server”. TAG considers a Visit to be acquired through “Paid Traffic Sources” if “the first page view is from a Paid Traffic Source”. A “Paid​ ​Traffic​ ​Source​” is defined by TAG as any “third party that receives monetary consideration from a publisher to drive traffic to another publisher” seeking to acquire more visitors.
