An explainer hook shows or explains how the product works in the first frame, the first three seconds of a video or the headline of a static. Instead of claiming a result, the ad answers the question the viewer is already asking: what does this thing actually do? It might be a screen recording of the app, a cutaway of the product, a diagram with arrows or one plain sentence that names the mechanism. The hook earns attention by being clear, not by being loud.
Start on the action, not on a logo or a title card. A hand pressing the button, a screen mid-task or the product at work tells the viewer what this is before they decide to scroll.
A hook has three seconds. Pick the single step that makes the product different and show only that. The rest of the ad, and the page, can carry the other features.
Write the line the way a customer would say it to a friend: it does X, then Y. Jargon in the first sentence sends the viewer away before the explanation starts.
Most feeds autoplay muted. Pair the demonstration with a short on-screen caption so the explanation survives without audio, and keep the text large enough for a phone.
It is an opening that shows or explains how the product works instead of leading with a claim or a story. On a video it is the first frame or first three seconds. On a static ad it is the headline or the main image.
An explainer hook describes how the product itself works. A how-to hook promises to teach the viewer to do something, with or without the product. Many ads blend them, but the explainer keeps the product at the centre.
Anything where seeing the mechanism answers the first doubt: apps, gadgets, tools, skincare devices, subscriptions and services with a clear process. If the product explains itself at a glance, another hook may do more.
Run it next to a hook that leads with the result or a customer story, using the same body and offer. Comparing hooks against each other, with everything else fixed, tells you which opening your audience responds to.
