Latest / The Copywriting Podcast with Fexingo: Sales Letters, Headlines, and Persuasive Writing / How a Single Sensory Word Made Copy 53 Percent More Persuasive
Transcript
- Lucas: Let me start with a headline. 'Feel More Energy.' That's what a supplement brand ran for two years. It performed fine. Then they changed one word — switched 'more' to 'steady.' The new headline: 'Feel a Steady, Clean Energy.' And response jumped fifty-three percent. Luna: Fifty-three percent from one word? That's huge. What made 'steady' so much more effective? Lucas: Well, before we dive into the why, I want to quickly mention something. If you've ever used a copy tip from this show in your own work, maybe you've seen a lift yourself. We keep this podcast ad-free, and listener support at buy me a coffee dot com slash fexingo is what makes that possible. It's a small way to keep these episodes coming. Now, back to that word swap — the reason 'steady' outperformed 'more' is that it's a sensory word. Luna: Right. 'More' is abstract. You can't feel 'more.' But 'steady' evokes a physical sensation — like a smooth, even flow. Lucas: Exactly. There's actually neuroscience behind this. When you read a word like 'steady' or 'crisp' or 'smooth,' your brain's motor cortex lights up — the same area that activates when you physically experience that sensation. It's called motor imagery. Luna: So you're not just understanding the word intellectually, you're feeling it in your body. Lucas: Exactly. And that feeling makes the claim more believable. The supplement company's product wasn't just 'more energy' — it was a specific type of energy. 'Steady' hinted at no crash, no jitters. The sensory word did the work of a whole sentence. Luna: We see this a lot in other categories too. I remember a mattress ad that tested 'Comfortable Sleep' against 'You'll Sink Into a Cloud of Support.' The second lifted click-through by thirty-nine percent. Lucas: That's a great example. 'Cloud' is a sensory anchor. It's soft, it's enveloping. And 'support' reassures you that it's not too soft. So you get two sensory words working together. Luna: What about a framework? How do we find the right sensory word for our own copy? Lucas: Start by listing the physical qualities of your product. A notebook: smooth pages, sturdy cover, the sound of a pen writing. A software: fast, clean, responsive. Then pick the quality that matters most to your customer and ask: If they could touch or feel it, what word would they use? Luna: So for a project management tool, instead of saying 'Get organized,' you might say 'Feel the calm of a clutter-free workflow.' Lucas: Perfect. 'Calm' is sensory. 'Clutter-free' is visual. That combination triggers a mental image and a feeling at the same time. Luna: But can you overdo it? Too many sensory words might sound like purple prose. Lucas: Absolutely. One or two per headline or opening sentence is plenty. The goal is to anchor the reader in a specific sensation, not to overwhelm them. Think of it like salt in a recipe — a pinch enhances, a whole spoon ruins it. Luna: Let's test another example. A weight loss program used 'Lose Weight Fast.' They changed it to 'Lose Weight While You Sleep.' The second one didn't have an obvious sensory word, but 'sleep' still evokes a state. What's happening there? Lucas: Good catch. 'Sleep' isn't a typical sensory word — it's what I'd call an experience word. It activates memories of rest, ease, passivity. That's still more vivid than 'fast.' So the principle holds: concrete, experience-based language beats abstract claims. Luna: Right. 'Fast' is relative. 'While you sleep' is specific and imagine-able. Lucas: Exactly. And this applies beyond headlines. You can drop sensory words into the first sentence of a sales letter, or even into a call to action. A button that says 'Start Your Smooth, Simple Setup' will outperform 'Get Started' every time, because it gives the brain something to latch onto. Luna: I want to try this on our own podcast description. We say 'a show about copywriting.' What if we changed it to 'a show that makes copywriting feel simple and fun'? Lucas: That is a direct application. 'Simple' and 'fun' are both sensory — they predict an emotional experience. I'd bet it lifts our download rate, even if we only tested the metadata. Luna: So the big takeaway: when writing copy, don't just state a benefit — help the reader feel it by choosing words that evoke a physical sensation. Lucas: Exactly. The fifty-three percent lift from the supplement test isn't magic. It's just neuroscience working in your favor. One word can change everything. Luna: And you can start testing this today. Pick your top-performing page, find the headline, and swap one abstract word for a sensory one. Then measure. Lucas: Couldn't agree more. Thanks for listening, and we'll see you next time with another copywriting insight that you can actually use.
