Most people starting out believe that a longer description signals more value. It does not. A 400-word block of text describing a ceramic mug will lose a reader faster than six precise sentences that answer the questions a buyer actually has: what it holds, how it feels, whether it goes in the dishwasher.
The features-first trap
New writers tend to list features because features feel objective and safe. But a feature like stainless steel housing means nothing without context. The reader needs to know what that feature does for them on a Tuesday morning when they are running late. That translation from feature to consequence is the actual work of a product description.
This is not a creative writing exercise. It is a decision-support document. The person reading it is trying to decide whether to hand over money. Every sentence should help them do that.
Sounding professional versus sounding useful
There is a real pull toward formal language when writing descriptions, especially for services. Phrases like comprehensive solution or tailored approach feel authoritative. They are also empty. A bookkeeping service description that says we handle your monthly reconciliation, flag late invoices, and prepare your BAS on time tells a small business owner exactly what they are getting. The formal version tells them nothing specific.
Precision is more persuasive than polish. A reader who understands exactly what they are buying is far more likely to buy it.
The third myth worth naming is that good descriptions require a strong creative instinct. They do not. They require attention to what a specific buyer already knows, what they are uncertain about, and what would tip them toward a decision. That is a research habit, not a talent.
