Every concept in this sheet, plus the smaller terms it uses. Select a concept to open its card.

A
Ad creative
The image or video an advertiser runs in a paid placement, usually made in several sizes and versions so the best one can be found by testing.
B
Brand consistency
Using the same colours, fonts, logo placement, tone and image style in every asset, checked against the brand kit.
Brand kit
A brand's logo files, colour codes, fonts, image style, tone of voice and examples of what to do and avoid.
C
Colour and contrast
Palettes built from harmonies (complementary, analogous, triadic), brand colours given as HEX codes, contrast that keeps text readable, and grading that makes clips match.
Composition
Where things sit in the frame: one clear focal point, supporting elements, and white space (empty space) around them.
Creative testing
Running several versions of an ad, each changing one thing such as the hook or image, and keeping the winner by numbers like click-through rate and conversions.
D
Demand signal
Evidence that clients pay for a service: dated reports such as Upwork In-Demand Skills 2026 (AI video generation and editing +329 percent, AI images +95 percent, 2025 against 2024 earnings), plus live job posts and ads.
H
Hook
Whatever stops someone scrolling: the first one to three seconds of a video, or the single element that reads instantly in an image.
P
Product photography
Images of a product for shops, marketplaces and ads: clean packshots on white plus lifestyle scenes showing it in use.
S
Story structure
A simple shape for the message: problem, product, proof, call to action for ads; what it is, how it works, why it matters for explainers.
T
Thumbnail
The small image that represents a video and decides whether people click.
Typography
How text looks: typeface, size, weight, leading (line spacing) and kerning (letter spacing).
V
Visual hierarchy
The order in which the eye finds things, controlled by size, contrast, colour and position: first the hook, then the product, then the call to action.
