What is the reason for a loading bar appearing in place of an ad creative?
The display of a loading bar instead of an ad creative can occur for two specific reasons. It is important to note that in both scenarios, the ad impression is correctly registered and monetized.
Browser Performance Optimization
An individual user's web browser may proactively block an ad creative deemed to be "heavy" (i.e., excessively large in file size). This is a standard browser function intended to preserve page loading speed and optimize the user's experience. This behavior is sometimes observed with large creatives, particularly from partners like Google.
System-Side Quality Filter
The advertisement was preemptively blocked by our own internal system. This automated action is taken when a creative is identified as failing to meet our established quality assurance standards or content guidelines.
