An advertiser is launching a new product. They need to ensure a creative will run every time.What do they need to do?

To ensure a creative always runs, an advertiser must set up a default ad. A default ad acts as a fallback, guaranteeing that an impression is served even if no other targeted ad is eligible or available. This prevents blank impressions and ensures continuous ad delivery. Setting up geographic targeting or producing region-specific creatives are strategies for audience segmentation and ad relevance, not for guaranteeing an ad always runs. Enabling an account for mobile devices only restricts delivery to a specific environment, but doesn't ensure an ad will always be available within that environment.
