An ad may be rejected by a vendor if it:

The scenario where an ad may be rejected due to being "over K-weight" reflects guidelines and standards that vendors implement to maintain quality and consistency across the advertisements they run. K-weight refers to the unit of measurement used to assess the weight of an ad in terms of file size and complexity. Vendors often have strict limits on the maximum file size that can be accepted to ensure optimal delivery speeds, user experience, and bandwidth usage across various devices and networks.

When an ad exceeds this weight limit, it can lead to slower loading times, which can negatively impact user engagement and overall campaign effectiveness. By rejecting ads that exceed the K-weight, vendors aim to uphold their performance metrics and deliver a better experience for users. This practice also helps protect the advertiser's brand by ensuring that their ads do not perform poorly due to technical constraints.

Contextually, while submissions that conflict with existing inventory, lack sufficient funding, or are submitted late may also affect ad acceptance, the specific issue of exceeding K-weight directly pertains to the technical Quality Assurance checks that vendors apply to ensure that all ads function seamlessly within their digital platforms.
