Why this matters
When ten stores sell the same product with the same manufacturer description, Google sees identical content across all of them. It picks one version to rank — usually the manufacturer's own site — and treats the rest as duplicates. Your product pages become invisible. This is a thin content issue at scale.
Focus on three things: rewrite the first two sentences entirely in your own voice; add information the manufacturer does not provide — your own experience, answers to common customer questions, comparisons to similar products; and use the product's most important keyword naturally in the first 100 words and in the product title. Product schema combined with unique descriptions is a powerful combination.
For large catalogues, prioritise your bestselling 20 percent of products first. Use AI tools to assist with drafting, but always review and personalise the output — AI-generated descriptions that are not reviewed are often detectable to Google's quality systems. Add internal links from product pages to the parent category and to related products.
