Define
The product does the arguing. The viewer sees the thing work, not a slogan about the thing working.
Mechanism
Proof by performance. The claim is the action on screen or on the page: a visible, testable result the reader can replay.
Verdict
We can show a result in seconds.
Don't
The benefit is invisible, delayed, or social. A demonstration of nothing is a longer ad.
Copy skeleton
[SETUP: ordinary condition] [ACTION: use the product] [RESULT: visible change] [Why that result transfers to the reader] [ASK]
Gulf note
Short vertical demos for Snap, TikTok, and WhatsApp Status. In-store and mall demos still convert. Film them. The film is the receipt.
