Online shoppers scan product pages, they don't read them line by line — which means a bloated 500-word description often loses a buyer before they reach the one detail that would've closed the sale.

A workable structure

• One-line hook (10-15 words): the single biggest benefit
• Short description (40-80 words): what it is and who it's for
• Scannable bullet specs: the details shoppers compare between tabs

Why tight copy converts better

Mobile shoppers in particular are quick to bounce off dense paragraphs. A tight description that respects their time signals confidence in the product rather than trying to talk them into it with volume.

Check your draft before publishing

Run your description through a word counter to confirm it fits your target length across every product page — consistency in length also keeps your catalog visually uniform, which matters more for conversion than most sellers expect.
