Answer in brief
A product description that works opens with what the item is and who it is for, ties each benefit to a feature, then gives the facts a buyer checks: size, material, compatibility, care. Google Merchant Center wants the key details in the first 160–500 characters and keeps prices, links and comparisons out of the text. Every factual claim needs evidence before it is published.
A model text from Google: the Chromecast description
Most people who type product description examples into a search bar want a text to borrow. One of the best comes from Google itself. Its Merchant Center help page for the description attribute describes Google’s own Chromecast in three plain sentences. The first calls it “a media streaming device that plugs into the HDMI port on your TV”, the second says what you do with it, and the third lists the systems it works with.
The same page shows an AI-written version that keeps the facts and wraps them in talk of an endless entertainment hub. The facts sell in both, and the adjectives only add length. Every example below extends that skeleton. A first line says what the product is and who it is for, benefits are tied to features, the facts a buyer checks follow, and the text closes with proof and answers to the usual doubts.
What Google Merchant Center allows in the description field
Google’s product data specification allows 1 to 5,000 characters and advises putting the most important details in the first 160 to 500, since customers must click to read the rest. The text must agree with the title and the landing page. It describes only the product, not accessories, similar goods, the history of the business or its policies. A product sent without any description gets a warning and may perform worse.
The list of exclusions is useful for any shop. Google wants no comparisons of the “even better than X” kind, no links, no capitals for emphasis, and no price, sale dates, shipping, delivery dates or company name, which belong in other attributes. It does want size, material, age range, special features, technical specifications, shape, pattern and design, plus variant details such as colour or flavour. These are the rules as the help page reads in October 2026, so check it again before a large upload.
Clothing descriptions: fibre, fit and care before style
A garment description opens with the type, the fabric and the occasion: a lined wool coat for city winters says more than a paragraph about style. Benefits hang on features, so the lining is the feature and staying warm on a cold platform is the benefit. Then come fibre composition, cut and measurements, the size the model wears, care and country of origin. A coat that must be dry-cleaned is a different purchase from one that goes in the machine.
The fibre line is regulated. Your Europe, the EU’s portal for businesses, explains that a textile label lists fibres in decreasing percentage order and allows 100%, pure or all only for a product made of one fibre. The FTC’s guide to the Textile and Wool Acts treats internet advertising as written advertising: a description that names a fibre must give the label’s fibre content and say whether the item was made in the USA, imported, or both. A word like Pima or Egyptian must not suggest that the garment is made only of that premium cotton unless it is.
Kitchen appliance descriptions that answer with numbers
For a kettle, a blender or a dishwasher, the first line names the appliance, its capacity and the household it suits. The doubts are practical: dimensions, power, noise, the plug or voltage for the country, box contents and cleaning. Each benefit should point at one of those numbers. Quiet enough for an open-plan flat means little until the decibel figure from the manufacturer’s sheet stands next to it.
Some appliances also carry a legal label. Your Europe lists cooking, refrigeration, and cleaning and drying among the categories that need an EU energy label, and says an online shop must show it near the price, in full or as a class arrow linked to the label and the product information sheet. The Commission’s Energy Efficient Products portal adds that this applies on every page showing the product, the basket included. The description need not repeat the class, but it must never contradict it.
Cosmetic descriptions where one word changes the legal category
A cosmetic description opens with the product type, the skin or hair it suits, the texture and the volume, then gives the ingredient list, how to apply it and how long it keeps once opened. The claims line needs the most care. The US Food and Drug Administration explains that intended use can be established by claims on the label, in advertising and online. Claims to restore hair growth or reduce cellulite are drug claims, and an antidandruff shampoo is both a cosmetic and a drug.
Green words became riskier in the EU this autumn. The European Commission’s Questions and Answers on Directive (EU) 2024/825 give 27 September 2026 as the date of application and cite generic claims such as eco-friendly, green and biodegradable, banned unless the trader shows recognised excellent environmental performance, such as the EU Ecolabel. A claim stops being generic when its specification appears clearly on the same medium, the online shop included. The Commission contrasts generic climate-friendly packaging with a statement that 100% of the energy used to produce the packaging comes from renewable sources.
Digital product and spare part descriptions built on compatibility
A digital product, such as a template, an e-book, a font or a program, is bought unseen. Its first line names the format and the job it does, then the version, the devices and software it opens in and what the licence allows. Your Europe says sellers of digital content must inform customers about interoperability with hardware and software and about functionality, including geographical restrictions and whether personal copies are allowed. Google’s Chromecast text does the same in a single sentence.
A spare part is sold by its number, so the opening line gives the part name, the manufacturer’s part number and the models it fits. eBay’s item description policy refuses Does not apply or N/A in required identifiers such as brand, UPC or MPN when the manufacturer has provided them. For vehicle parts, eBay recommends compatibility data, up to 3,000 combinations of years, makes, models, trims and engines depending on the category. If a part does not fit a vehicle on its chart, the seller must accept the return even without a returns policy.
Claims, evidence and search words in a product description
A description is advertising, and regulators read it that way. The FTC’s guide for small business says claims must be truthful and backed by evidence before the ad runs, implied claims included: a mouthwash said to kill the germs that cause colds implies that it prevents colds. The UK Competition and Markets Authority, in guidance on rules in force since 6 April 2025, says factual claims should be supported by evidence or may be found false. On a marketplace, both the operator and the seller may be held responsible for a listing that lacks required information.
Search wording follows the same honesty. Google’s SEO Starter Guide asks writers to anticipate the words people use, since some search for charcuterie and others for cheese board, and to create content rather than copy it. Google’s spam policies call filling a page with keywords to manipulate rankings keyword stuffing. So the buyer’s word for the product goes in the first line, the technical term appears once among the facts, and the manufacturer’s paragraph that every reseller pastes gets rewritten.
Marketplace or own store: product data to prepare before ordering
Where the text lives changes its shape. On a marketplace it sits inside the platform’s fields and rules: eBay’s policy says everything in a listing must relate directly to the item or the seller’s terms, the condition must match across title, description and item specifics, and the text must be in the site’s main language. In your own store the page is yours, but a catalogue that feeds Google Shopping must match its Merchant Center data. One set of checked facts can feed both.
Before ordering descriptions or product cards, fill one sheet per item: name and variants, dimensions, composition from the label, care, compatibility and part numbers, box contents, and the documents behind each claim, from test reports to ecolabel certificates. Add the questions customers ask and the reasons for past returns, because those are the doubts the text must answer. Name the channels and languages too. With that sheet, a writer spends the time on wording, not on chasing facts.
The product description examples above are enough for a shop with a dozen items and an owner who knows them: start with the best seller and write the rest yourself. Ordering makes sense with hundreds of items, several marketplaces or languages, or claims about cosmetics, textiles or the environment that need a second reader. VITON13 Studio works remotely, with clients in any country, on Wildberries and Ozon product cards, where slide design and card texts with search attributes are separate services. Bring the sheet and one description you like, and ask for the scope, timeline and price in writing.
Practical checklist
- Write the first line of each description: what the product is, who it is for and its key size or format.
- Keep the details buyers check within the opening 160–500 characters, before any story about the brand.
- Copy fibre composition, energy class and part numbers from the label or the manufacturer’s sheet, not from memory.
- Remove generic green words and any claim you cannot prove with a test report, a certificate or a measurement.
- Build one product data sheet per item and reuse it for the marketplace card, the store page and the Google feed.
Questions and answers
How long should a product description be for Google Shopping?
Google Merchant Center accepts anything from 1 to 5,000 characters. The opening matters more than the total: Google advises placing the key details within the first 160 to 500 characters, since shoppers see the rest only after a click. Longer text is fine when every sentence adds a fact.
Can I reuse the manufacturer’s product description in my own store?
Whether you may reuse it depends on the manufacturer’s terms, so check them, and check your own case with a specialist if in doubt. For search, Google’s SEO Starter Guide prefers content you write yourself. Keep the verified facts and rewrite the wording around your buyers’ questions.
Should a product description mention the price or delivery times?
Not in a Google Merchant Center feed: price, sale dates, shipping and delivery dates go into their own attributes, and Google lists them among things to keep out of the description. On your own product page they can sit near the buy button, where they are easier to keep current.
Is it acceptable to write product descriptions with AI tools?
Google Merchant Center takes AI-written descriptions, but they must arrive in the structured_description attribute with the digital source type trained_algorithmic_media. Whoever writes the text, its claims still need evidence, so a person should check every fact against the product data before publishing.
What makes a spare part description trustworthy to a buyer?
The brand, the manufacturer’s part number and the exact models, years and engines it fits. On eBay, required identifiers cannot be filled with N/A when the manufacturer has supplied them, and a part that fails to fit a vehicle listed on its compatibility chart has to be taken back. A clear photo of the number on the part helps as well.
