The most obvious way in which DSPs are important to mobile marketing also applies to automation in general: this process allows marketers to avoid spending time and energy on something that can be completed by an automated machine. Rather than manually contacting hundreds of publishers with offers to advertise, DSPs help advertisers quickly set up campaigns and manage them with ease. This allows user acquisition experts to spend more time working on other valuable areas – such as user base segmentation – to improve performance long-term.
