1. Why clarity beats cleverness
People don't read marketing copy the way they read a novel — they skim it while half-distracted, deciding in seconds whether it's worth their attention. Confusing copy doesn't get a second chance; it gets a closed tab. Nielsen Norman Group's work on legibility, readability, and comprehension shows that the easier text is to process, the more likely people are to read it, believe it, and act on it. Clarity isn't a stylistic preference — it directly affects conversion.
The good news: clarity is mostly mechanical. You don't need to be a gifted writer. You need to apply a few consistent edits.
2. Swap big words for simple ones
Long, formal words make copy feel stiff and slow it down. They rarely add meaning — they just add friction. The U.S. government's plain-language standards put it plainly: prefer the familiar, usually shorter word. Their guidance on using simple words and phrases includes a long list of swaps worth stealing.
- "Utilize" → use
- "In order to" → to
- "Facilitate" → help
- "Approximately" → about
- "Commence" → start
None of these swaps lose meaning. All of them read faster.
3. Shorten your sentences
Long sentences force readers to hold several ideas in their head at once. Aim for an average of around 15–20 words, and vary the rhythm so it doesn't read like a list. The fastest way to shorten a sentence is to find the conjunction — "and," "but," "which," "so" — and consider whether it should be a full stop instead. Two clear sentences almost always beat one tangled one.
4. Use the active voice
The active voice ("we ship your order the same day") is shorter and clearer than the passive ("your order is shipped the same day by us"). It tells the reader who does what, which is exactly what they're trying to figure out. Passive voice creeps in when you're being cautious or vague — which is rarely what marketing copy should be. A quick check: if you can add "by zombies" after the verb and it still makes grammatical sense, you're in the passive voice. "The form was submitted (by zombies)" — rewrite it.
5. Cut filler and hedging
Filler words pad your copy without adding meaning, and hedging words quietly undermine your confidence. Cut or tighten them:
- Filler: very, really, actually, just, basically, in order to, the fact that.
- Hedging: we think, we believe, sort of, might possibly, in our opinion.
"We really think our tool can basically help you save quite a lot of time" becomes "Our tool saves you time." Same claim, far more confident.
6. Drop the jargon and "marketese"
Jargon excludes the very people you're trying to win over, and inflated promotional language — what NN/G calls "marketese" — actively erodes trust. Readers detest boastful, subjective claims with nothing behind them. Phrases like "best-in-class, end-to-end, synergistic solution" say nothing a customer can use. Replace them with concrete specifics: what it does, for whom, and what changes as a result.
7. Make it scannable
Even perfectly clear sentences are hard to read in a dense wall of text. Structure does half the work of clarity:
- One idea per paragraph — and keep paragraphs short.
- Use descriptive subheadings so someone scanning can follow the argument.
- Break lists out of sentences (like this one).
- Bold the occasional key phrase — sparingly, or nothing stands out.
Clarity is hard to judge in your own writing because you already know what you meant. That's where a second pair of eyes — or a tool — helps: it flags the long sentences, filler, and reading level you've stopped noticing.
