Should you really remove manufacturer descriptions from your product listings?

Why does Google emphasize unique descriptions in e-commerce?

E-commerce sites have long operated on a simple logic: mass importing manufacturer descriptions to quickly fill thousands of listings. The problem is that dozens (or even hundreds) of resellers use exactly the same text.

Google faces virtually identical pages across different domains. In this context, the algorithm must decide: which version deserves to rank? Often, it is the major players (Amazon, Cdiscount) that win due to their domain authority, not content quality.

What does it really mean to "not include generic descriptions"?

Google refers to active removal, not simply adding original text as a complement. If you have written a unique description for a product, the recommendation is to remove the manufacturer text block from the page.

The idea behind this directive: avoid having your page perceived as a mix of unique and duplicate content. Google prefers a 100% original page (even if shorter) to a mixed page that dilutes the signal.

Does this guideline apply to all types of e-commerce sites?

This statement primarily targets sites selling the same products as thousands of competitors. If you are the only distributor for a brand or if you sell handmade creations, the duplication issue does not arise in the same way.

However, for a site listing widely distributed tech, fashion, or cosmetic products, the issue of unique content becomes a matter of SEO survival. Without textual differentiation, you are in direct competition with industry giants on their territory: raw authority.

• Manufacturer descriptions = massive duplicate content across dozens or hundreds of competing sites
• Google is looking for a signal of added value to differentiate resellers of the same product
• Remove the generic text (not just add to it) if you have created original content
• The stakes are more critical for multi-brand sites than for exclusive distributors
• A 100% unique page (even if short) is better than a unique/duplicate mix according to Google

Is this recommendation really applicable on a large scale?

Let’s be honest: writing unique descriptions for 10,000 references is a huge task. Google offers school advice but does not measure the operational cost for a site with a deep catalog. Most e-commerce merchants lack the budget or editorial resources to achieve this.

In practice, we observe that well-ranking e-commerce sites do not systematically remove manufacturer specifications. They keep them in technical tabs and add unique content in the introduction or in advice/use sections. Google says "not to include", but the field shows that a smart mix works if the unique/duplicate ratio leans in the right direction.

What nuances should be added to this directive?

The first point: Google mentions “distinct added value”. This doesn’t mean you need 500 words of marketing fluff. A unique description of 80 words that genuinely guides the purchase (use case, comparison, sizing advice) is worth more than 300 generic words hurriedly rephrased.

The second nuance: structured technical characteristics (spec tables) are not considered "textual content" in the classic sense. No one is going to write by hand "Weight: 1.2 kg" differently for each reseller. Google can differentiate between a specs block and a narrative description paragraph. [To verify]: no official data specifies whether specs tables fall under this penalizing duplication logic.

In what cases does this rule not apply?

If you are the exclusive official reseller of a brand in your market or an exclusive distributor, the problem of external duplication disappears. You can keep the manufacturer text without risk, as no one else is publishing it.

Another case: highly technical products (professional equipment, chemistry, medical) where the manufacturer text is standardized documentation. Rewriting "Complies with ISO XYZ" in a "unique" version adds nothing for the user. In these situations, it’s better to add usage guides, industry FAQs, or customer feedback rather than reformulate normative data.

What should you do on an existing e-commerce catalog?

Start with an external duplication audit: take 50 strategic product listings (those generating traffic or having strong commercial potential) and check how many sites publish the exact same text. If you are competing with 200 resellers on the same content, you know those pages are at risk.

Next, prioritize: write unique content for your best-sellers and high-margin products first. There’s no need to tackle everything at once. For secondary references, you can temporarily keep the manufacturer text in the meantime, but isolate it in a "Technical Characteristics" block rather than in the main description.

What mistakes should you avoid when writing unique descriptions?

A classic mistake: rephrasing the manufacturer text with synonyms. Google is not fooled by light spinning. A real unique description brings a different angle: purchasing advice, experience feedback, comparison with a competing model, sizing advice, usage ideas.

Another trap: keeping the manufacturer text at the bottom of the page "for SEO" thinking Google won’t see it. If the text is indexable, it counts. Either remove it, or integrate it in an accordion/tab with clear technical markup (schema Product), but don’t play hide and seek with the algorithm.

How can you check if your product content strategy is working?

Use a ranking tracking tool on your long-tail product queries ("[brand] [model] review", "difference between [product A] and [product B]"). If your unique descriptions are well done, you should capture these informational queries that precede a purchase.

Also monitor the click-through rate in SERP: a meta-description drawn from unique and engaging text performs better than a cold and technical manufacturer description. If your CTR rises on the revised pages, that’s a good sign. Finally, cross-check with conversion data: well-thought-out unique content often improves the conversion rate, not just SEO.

• Audit external duplication on your 50 priority product listings
• Write unique content on best-sellers and high-margin products first
• Remove (or isolate in a technical tab) the manufacturer text on pages with original content
• Avoid spinning: bring a truly differentiating angle (usage, comparison, advice)
• Track long-tail positions and CTR of revised pages
• Test on a sample before rolling out to the entire catalog
