Saíram os novos guidelines do IAB para mensuração de publicidade com vídeos.

Há um grande crescimento no interesse para veicular anúncios em vídeos e o objetivo é padronizar os formatos, buscando a simplicidade, a eficiência e também formas de medir resultados.

The guidelines focus on the most widely used current in-stream ad products, including linear video ads, non-linear video ads and companion ads. They were created in order to meet the following marketplace needs:

* Simplifying digital video ad buying across multiple sites through minimum common ad specifications for video, overlay and companion ads.
* Achieving more efficient operations through a common set of creative submission guidelines.
* Increasing consumer understanding of ad interactions and environments through best practice recommendations for creative development and player environments.
