Overview

Before any auctions from exchanges are forwarded to an individual customer's Buyer Cloud, FreeWheel performs some basic hygiene on the requests. This page explains some reasons why a bid request might be dropped prior to customer filtering.

Cases Where Bid Requests Are Dropped

User Opt-Out

Users may choose opt-out from being served ads by FreeWheel by following opt-out instructions provided on the FreeWheel Privacy Policy page.

If the user ID on a particular bid request is flagged as “opted out,” the bid request will be dropped.

Cases Where Bid Requests Are Not Dropped

Do Not Track

The “Do Not Track” (DNT) setting is not honored. Requests marked as "DNT" are not dropped or altered in any way.

Limit Ad Tracking

“Limit Ad Tracking” (LMT) is a device-level opt-out setting that allows users to limit the amount of information sent from their device for advertising purposes, including omitting their device ID.

Bid requests flagged as LMT are eligible to bid on, and user personal data is obscured. For more information, see Limit Ad Tracking (LMT) Processing Logic.
