Hook
Quick answer
What is hook?
The opening line or moment of a piece of content or copy, designed to earn attention before anything else can be sold.
In plain English
A hook is the first three seconds of a video, or the first sentence of an email or page — its only job is to stop the scroll or the skim and make someone want the next line. Without a strong hook, nothing after it gets read or watched.
Example
"I sent 4 emails last month and made $9,400 — here's exactly what I said."
Why it matters
OfferConverter AI's viral content model treats the hook as a non-negotiable rule for every social post it writes, and subject line rules apply the same idea to email.
