Definition of ad specs in advertising

Ad specs, short for advertising specifications, refer to the detailed guidelines and requirements for creating and submitting advertisements. These specifications include dimensions, file formats, file sizes, resolutions, aspect ratios, and any other technical details necessary to ensure that ads are displayed correctly and perform optimally across various platforms and devices.
