AI ad glossary: 25 terms explained in one line each

By the Logicive team · Updated 17 August 2026 · 7 min read

Advertising has a habit of using ordinary words to mean specific things, and AI tooling has added a second layer of vocabulary on top. Here is the working set, defined the way a person would explain it across a table. No entry needs the one above it.

The short version

A packshot is the plain product photo everything else is built from.
A hook is the first two seconds or the first line, and it decides everything after it.
UGC describes a style, not necessarily a source.
A creative test compares concepts, not colours.

Packshot: A packshot is a plain, well-lit photograph of the product on its own, usually against a simple background, used as the reference every generated scene is built around.
Hook: The hook is the first line or the first two seconds of an ad, the part that decides whether the rest is ever seen.
UGC: UGC means user-generated content, but in advertising it usually describes a style: handheld framing, casual voice, a person showing you something rather than a brand presenting it.
Creative: The creative is the ad asset itself, the image or the video, as distinct from the targeting, the budget and the landing page it points to.
Variation: A variation is another version of the same ad idea, changed in one deliberate way so that comparing it with the original teaches you something.
Creative test: A creative test runs several genuinely different concepts against the same audience at the same budget, so the winner is chosen by results rather than by taste.
Aspect ratio: The aspect ratio is the shape of the frame, written as width to height: 9:16 for full-screen vertical placements, 1:1 for square feed posts, 16:9 for landscape.
Brand file: A brand file is a stored record of a brand's logo, palette, tone of voice and house rules, opened automatically before each ad so the brand does not have to be re-explained every time.
House rule: A house rule is a standing instruction that applies to every ad without being restated, such as "always show the label" or "never promise results".
Media plan: A media plan is the short written decision that accompanies an ad: who should see it, what the hook is, and what you are willing to spend to find out whether it works.
Prompt: A prompt is the written instruction given to a generative model; for ads, the useful ones describe a place, a light and one focal idea rather than asking for quality.
Brief: A brief is the human-readable version of the same thing: one sentence naming where the product is and how the moment should feel.
Render: A render is a single generated output. Renders vary between runs of the same prompt, which is why generating a set is normal rather than a sign something went wrong.
Upscaling: Upscaling enlarges an existing image to a higher resolution after generation, adding pixel count without adding detail that was never captured.
4K: In this context 4K means an image or video roughly 3,840 pixels wide, large enough for product pages, marketplaces and most print-adjacent use.
Credit: A credit is a unit of generation cost. What one credit buys differs by tool and by model: a small image may cost one, a second of high-resolution video considerably more.
Static: A static is a still-image ad, as opposed to a video ad. Statics are cheaper to produce and to test, and remain the majority of what most stores run.
Cinematic: Cinematic describes the polished, deliberately lit and composed style associated with brand films and studio production, as opposed to the handheld UGC look.
Retargeting: Retargeting shows ads to people who have already visited your site or engaged with you, an audience where polished brand creative typically outperforms casual styles.
Cold audience: A cold audience has never heard of your brand, which is why first-touch creative usually has to look like content rather than like an advertisement.
Funnel: The funnel is the path from never having heard of a product to buying it, and different ad styles do different jobs at different points along it.
Disclosure: Disclosure is telling viewers that content was generated or materially altered by AI, required by ad platforms such as Meta and TikTok when the result could be mistaken for a real person or event.
Endorsement: An endorsement is any ad message a viewer would reasonably take as the opinion of someone other than the advertiser, which is why the FTC guides treat an invented testimonial as deceptive rather than creative.
Generative engine optimisation: Generative engine optimisation, or GEO, is the practice of structuring a page so that AI answer engines can retrieve, quote and cite it, rather than only ranking it in a list of links.
Answer engine: An answer engine is a search product that replies with a written answer and citations instead of ten blue links, which is what ChatGPT, Perplexity and Google's AI features all do.

How to use this list

These are the terms that come up when a store starts making its own ads. If you only read four, read packshot, hook, brief and creative test: those four carry most of the practical weight, and the rest are vocabulary you can look up when somebody uses them at you.

Most arguments about ads are really arguments about definitions. Agreeing on these twenty-five removes about half of them.

Questions people ask next

What is a packshot in advertising?

A packshot is a plain, well-lit photograph of a product on its own, usually against a simple background. It is the reference image everything else is built from, which is why a sharp packshot with a readable label is worth more than a stylish one.

What does UGC stand for?

UGC stands for user-generated content. In advertising it has drifted into meaning a style rather than a source: handheld framing and a casual, person-to-person voice, which can be produced with or without an actual customer being involved.

What is the difference between a prompt and a brief?

They are the same instruction written for two audiences. A brief is how you would describe the ad to a person, and a prompt is that description handed to a model. The good version of either names a place, a light and one focal idea instead of asking for quality.
