Clarity Over Cleverness: The Plain-Language Pass
Clever copy makes the reader work to admire the writer. Clear copy lets them decide. This guide gives a plain-language pass for headlines, offers and explanations, without stripping out voice or character.
The short answer
Choose clarity wherever cleverness and clarity compete, which on a selling page is nearly everywhere. A headline that needs decoding, a pun that hides the product name, an elegant sentence that could mean two things: each spends the reader shortest resource, attention, on the writer instead of on the decision. Plain language is not plain personality. Voice survives in word choice, rhythm, specifics and honesty. What the plain-language pass removes is friction: jargon the customer does not use, abstract nouns where a verb would do, long sentences where the point gets lost, and any line whose main achievement is sounding impressive in the office.
What cleverness costs at the point of decision
On an entertainment page, a puzzling line is a small delay. On a product, booking or payment page, it sits between the visitor and an action they were considering. The reader context matters too: people read selling pages while distracted, tired, comparing, or anxious about spending. A line that requires a second read competes with the offer terms, the guarantee and the price for the same attention. None of this bans wit. A genuinely apt, clear line with character is memorable and can carry an offer further. The test is sequence: understood first, appreciated second. If the order reverses, the line belongs in a social post, not in the corridor to a purchase.
The plain-language pass, step by step
Work through the draft in passes, one fault at a time. Replace internal terms with the customer words collected in voice-of-customer copy. Turn abstract nouns into verbs where the sentence allows: make a decision becomes decide, where it reads naturally. Cut every word that changes nothing if removed. Split any sentence you cannot say aloud in one breath at the point where the thought turns. Move numbers and terms from subordinate clauses into the main line where the reader will see them. Then read the whole page aloud at speaking pace. Anywhere you stumble, a reader on a screen will stumble harder.
Jargon: translate, explain or cut
Some technical words are necessary because they are the accurate names of things a buyer must confirm: compatibility standards, materials, qualifications. Keep those, and explain each once, briefly, at first use, in customer terms. The jargon to cut is the kind that signals belonging rather than meaning: synergy-style business words, internal range names presented without a plain description, abbreviations the business uses daily and the customer meets for the first time on this page. A useful rule is that every specialised term on a persuasive page must pay rent: it either helps the reader confirm fit or it helps them trust the standard of work. Otherwise it is rent-free fog.
Keep the voice, lose the fog
Businesses resist the plain pass because they fear sounding like everyone else. The fear misplaces where distinctiveness lives. Voice is in what you notice and choose to say: the specific detail about how the product behaves, the honest limit, the local knowledge, the way a service describes its own process. Those survive plain language easily, and in fact read more strongly without fog around them. Keep a short list of the phrases and stances that are genuinely yours, as the story guide story and origin copy develops, and let the plain pass protect them by clearing the generic cleverness that was diluting them.
Hunt ambiguity, not just difficulty
The most expensive unclear sentences are not the obviously hard ones. They are the smooth sentences two readers understand differently: delivery times that could start from order or from dispatch, a free offer whose free part is unclear, a service area described so loosely that two towns disagree about coverage, a pronoun pointing at two possible products. Test for ambiguity by asking a reader to paraphrase the terms back to you, not merely to say they understood. Where paraphrases differ, the sentence, not the reader, is at fault. Terms, prices, timescales and eligibility deserve this stricter test every time they are edited.
Where cleverness can stay
Some surfaces reward character more than speed: the about page story, a campaign line for an audience that already knows the offer, a name or tagline supported everywhere by plain explanation. Even there, the supporting copy must do the clear work, so the clever line never carries the offer alone. Judge each case by the reader state: the warmer and less time-pressed the reader, the more room there is. The colder the traffic and the nearer the money, the stricter the clarity rule. That single sliding scale will settle most arguments about a favourite line without needing a house rule against humour.
