Clever copy gets shared internally and praised in meetings. Copy that converts often looks plainer than everyone expected. These are not the same skill, and confusing them is one of the more expensive mistakes a marketing team makes.
What “Sounds Good” Optimizes For
Clever copy is written to impress the room approving it — wordplay, tone, a memorable line. It’s optimized for the internal audience, which is not the same audience the copy actually has to persuade.
What Sells Optimizes For
Copy that converts is written for someone with a specific hesitation, at a specific point in a decision, who needs a specific objection answered. It’s often less flashy because flashiness isn’t what removes the reader’s doubt.
The Test That Actually Matters
- Does this line answer a real objection the reader has, or just sound sophisticated?
- Would this still work if the clever wordplay were removed?
- Is the call to action clear, or buried under style?
Why This Requires Testing, Not Taste
The team’s internal opinion on which version “sounds better” is a weak predictor of which version converts — the only reliable answer comes from testing against the actual audience, not a meeting room.
