Final answer:
The video solution with the lowest CPM among in-stream video formats is typically one that targets mobile users with short, unskippable ads. The exact CPM can vary based on several factors, including platform and ad demand.
Step-by-step explanation:
The video solution with the lowest CPM (Cost Per Mille) among in-stream video formats, which serves predominantly on mobile, is generally the one that targets mobile users with shorter attention spans and offers unskippable ads. These tend to have a lower CPM because they are less intrusive and are more likely to be completed by the viewer. However, it's important to note that CPM can vary widely depending on the platform, the targeting specifics, the geographical location, and the overall demand for the ad space at the time.
Advertisers looking to optimize their budget often seek out such video solutions to ensure their campaigns are cost-effective, especially when targeting mobile users who might not engage with longer content formats. Many social media platforms and ad networks offer variations of these types of ads, and performing A/B testing or consulting with the ad platform's support can result in more precise information based on current trends and rates
