Technical specifications for CTV advertising creatives.
Last modified: 26 March, 2025
Preamble
The following quality criteria are obligatory and serve as a guideline for the best possible monetisation of CTV inventory. The contents of the following guidelines are based on market developments over the past 24 months. The performance values are assessed by smartclip’s proprietary systems as well as well-known ad verification providers.
The concept of “premium” is based on proven performance values that significantly profit from placement within CTV environments. Infringement or violation of these guidelines could lead to exclusion from monetisation and/or a loss of revenue. Additionally, buyers evaluate the criteria individually, and smartclip conducts detailed analyses of intentional or unintentional violations of the criteria on a case-by-case basis. Therefore, complying with these guidelines can ensure the best possible revenue generation for a publisher’s inventory. Furthermore, the below-mentioned criteria offer the opportunity to stand out amongst other competitors within the CTV segment.

Correct transmission of the consent string signal according to TCF 2.2 (EU only)
