you want to run your campaign for your dry-cleaning service across three different publishers, each with different video creativ
e specifications. one accepts only mp4-transcoded video creatives, one accepts only 480x480 companion ads, and the third hasn't provided specifications. how should you traffic this campaign?
The publisher, the user, and the ad server are all involved in the third-party ad serving (3PAS) paradigm of ad delivery.
Instead of serving an ad directly to the user's browser, the publisher instead sends the browser to an ad server where the ad is saved via an ad tag. Companion banners are image advertisements that play concurrently with other video or audio advertisements. In audio advertising, companion banners are shown to viewers as your audio ad is playing on a screen-equipped device, such as a smartphone or a computer. Go to your creative properties and open the Companion Creatives section. Select Add companions from the drop-down menu. You can add new creatives or assign already-existing ones.
In design phase developers make prototypes. The prototype is the solution without actual implementation. That prototype is shown to the user for the purpose of getting feedback. So design phase of SDLC involves making improvements based on user feedback.
