Third-Party Ad Specifications

Third-Party Served Ad Formats

In addition to our site-served, custom all-screen Creatives, we can also accomodate creative bookings that are served by a third-party. Tremor Video DSP recommends observing these specifications when submitting assets for third-party video ad serving.

If your ad tag can support multiple media files, feel free to include a larger video file; the media file that is most appropriate for the resolution of the device will deliver to the impression.

Delvering to Mobile Screens

Tremor Video DSP recommends including at least one < 3MB media file in your ad tag when delivering to a mobile in-app screen. This limitation helps to standardize user experience across different connection speeds such as 3G, 4G, LTE, wifi, and so on.

When the video file size is larger than 3MB, there can be a 1-2 second delay in loading the video ad, which can cause some mobile publishers to abandon the ad, causing use rate issues for the delivery of this placement.

When a third-party serves the ad, user-initiated sound settings cannot be configured by the advertiser; that setting is always configured by the publisher that requests the ad.
