Does adding unique copy to every product page actually pay off?

On the products people search for, it can; across every product in a large catalog, the hours are unlikely to come back. Unique copy is an investment per page, and its return depends on what the page can earn: search demand for the product, the margin on it, and how many other stores already compete with the same manufacturer text. A thousand-product catalog with a hundred products that sell and nine hundred that sit has a hundred pages worth writing for first.
Sorting the catalog
| Product group | What to write | Why |
|---|---|---|
| Products with search demand and competitors carrying the same text | Original description, your own photos, answers to buying questions | These pages compete for searches, and identical copy gives Google no reason to pick yours |
| Products you sell that no one else stocks | Clear specifications and a description that explains the item | No competing copy exists, so the bar is clarity, not difference |
| Long-tail items with little demand | Clean, complete specifications and the standard description | Original copy costs more than these pages can earn |
| Variants of one product (sizes, colors) | One strong page for the product, with variants selectable on it, unless a variant needs a page of its own because of its own price, stock, images or search demand, such as a model people look up by name; then it can keep its own page, related to the others through Google's product variant structured data | Writing separate copy for each variant that differs only in an option picked on the page splits one product into a set of thin pages |
What “unique” should mean
Rewording the manufacturer’s paragraph does not make a page more useful; it makes it different in wording and the same in substance. Copy that pays off adds information the buyer needs and other stores do not provide: how the item fits or measures, what it works with, what is in the box, how it compares with the model below it. Google’s guidance on writing high quality reviews asks reviewers for evidence of their own experience with what they review. A product page is not a review, and that guidance does not govern it, but the same kind of first-hand detail is what separates one store’s page from the copies.
Measuring whether it worked
Pick a group of products, write for them, and leave a similar group unchanged, matched on category, demand, price range and season, and chosen before you look at their recent numbers. Compare impressions, clicks and sales for both groups over the same weeks. If the written group pulls ahead, extend the work to the next group by demand. If it does not, first ask whether the test could have shown a difference: enough weeks for Google to recrawl the pages, groups large enough and still comparable, no sale or seasonal swing hitting one group only. If the test holds up, look at the other explanations one by one: price, stock, whether the pages are indexed, the page experience, or a category page that never sends anyone to them. The reason identical manufacturer copy holds pages back has its own answer in why thin product pages with manufacturer copy fail to index. Write first for the products that can repay it, and test before writing for the rest.
