Words and Phrases That Kill Conversions on Your Sales Pages

Certain words and phrasing patterns consistently undermine persuasive copy, often without the writer realizing it. Being aware of these common pitfalls helps you edit more effectively.

Vague Superlatives Without Support

Words like "amazing," "incredible," or "revolutionary," used without concrete evidence backing them up, read as empty marketing noise rather than genuine, credible claims — specificity persuades where vague superlatives don't.

Hedging Language That Undermines Confidence

Phrases like "we think," "hopefully," or "we try to" signal uncertainty that undermines the confidence a reader needs to feel to commit to a purchase decision.

Overly Technical Jargon Without Translation

Industry jargon that isn't translated into genuine reader benefit creates confusion and disengagement, particularly for readers not already deeply familiar with your specific field.

"Just" and Other Minimizing Language

Phrases like "it's just" or "simply" used to minimize genuine complexity can read as dismissive of legitimate reader concerns, rather than genuinely reassuring.

Passive, Evasive Constructions

Passive voice ("mistakes were made," "your order will be processed") tends to feel evasive and less direct than active, confident language taking clear ownership.

Generic Claims Any Competitor Could Make

Phrases like "quality service" or "customer satisfaction guaranteed," without specific substantiation, fail to differentiate you from every other competitor making identical, unsupported claims.

Excessive Urgency That Reads as Manipulative

Artificial scarcity or urgency language, when it doesn't reflect a genuine constraint, tends to be recognized as manipulative and can actively damage trust once identified as inauthentic.

Overly Complex Sentence Structures

Long, complicated sentences make readers work harder to extract meaning — clear, direct sentences persuade more effectively than impressive-sounding but hard-to-parse alternatives.
