| Term                     | Meaning                                                                                                                                                    |
| ------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **A/B testing**          | Running multiple variations of an ad to learn which performs best.                                                                                         |
| **Aspect ratio**         | The width-to-height ratio of the ad. 9:16 vertical, 1:1 square, 4:5 portrait, 16:9 horizontal.                                                             |
| **Avatar**               | The person (real or AI-generated) who appears in the ad.                                                                                                   |
| **Call to action (CTA)** | The line that tells the viewer what to do next — "Shop now," "Use code," etc.                                                                              |
| **Creative**             | Industry term for the actual ad — the video, image, copy, and design assets.                                                                               |
| **Creative fatigue**     | When an audience has seen an ad too many times and stops responding. Solved by refreshing creative.                                                        |
| **DTC**                  | Direct-to-consumer — brands that sell directly through their own storefronts.                                                                              |
| **Format**               | The structural style of the ad. Ad Studio offers seven (UGC, Unboxing, Review & Tutorial, Virtual Try On, Pro Virtual Try On, ASMR, Hyper-Motion Product). |
| **Hook**                 | The first 1–3 seconds of an ad, designed to stop the scroll and earn the rest of the attention.                                                            |
| **Performance ad**       | An ad designed to drive a measurable action (click, install, purchase), not just brand awareness.                                                          |
| **Setting**              | Where the ad takes place — the visual context that surrounds the product and avatar.                                                                       |
| **Stop-scroll**          | The action of pausing on an ad mid-feed. The first job of any hook.                                                                                        |
| **UGC**                  | User-generated content. A format that mimics casual, real-person content rather than polished production.                                                  |
| **URL to Ad**            | Ad Studio's tool for generating ads directly from a product page URL.                                                                                      |
| **@ shortcut**           | Typing @ in the prompt to pull in specific products or avatars from your library.                                                                          |
