How Long Should a Product Description Be? The Real Limits

Two published facts back that up. Google puts it in writing, in a self-check for writers: "Are you writing to a particular word count because you've heard or read that Google has a preferred word count? (No, we don't.)" And Merchant Center, which republishes your description in Google Shopping, recommends around 500 to 1,000 characters, roughly 85 to 170 words. The limits that bite come from feeds and store templates, not rankings.

How long should a product description be for each type of product

Sort by the buyer's open question, not the price tag. Price is a poor proxy for uncertainty: a $900 chair somebody has bought before needs less copy than a $30 cable with a compatibility problem.

Shopify lands in a similar place, suggesting 50 to 100 words for simple, low-cost items and 200 to 300 or more for complex or expensive ones. It cites no study for those numbers, and the bands in the table are experience, not evidence, either.

Break the bands when the product says to. If 40 words answer every question your support inbox gets, the description is finished. If 600 words still do not say whether the lid is dishwasher safe, it is not. Whether you land on 180 words or 220 makes no difference to anyone, Google included.

Does product description length matter for SEO?

Not directly. The word count line above sits in Google's list of warning signs for content written for search engines first. Elsewhere on the same page, Google asks whether content provides "a substantial, complete, or comprehensive description of the topic". Length is not a target, but thin is still thin.

There is no 300-word minimum either. What hurts is copying. Google's spam policies list "reproducing content feeds from other sites without providing some type of unique benefit to the user" as scraping, and describe thin affiliate pages as ones where "the product descriptions and reviews are copied directly from the original merchant without any original content or added value". Run the manufacturer's copy and you are publishing the same text as every other stockist.

Mass production is the other risk. The same page names "using generative AI tools or other similar tools to generate many pages without adding value for users" as scaled content abuse. Padding every SKU to 500 words to hit a target can fall under it, whoever or whatever does the typing.

So rewrite supplier copy before you add a single word. Our guide to rewriting website content walks through it, from auditing what you have to the rewrite itself. Put the main search phrase in the product name and once in the opening line, where a buyer would use it anyway. Cut any sentence that exists only to repeat it.

Two more catalogue fixes are worth doing in the same pass. Filter URLs such as ?size=m mostly belong out of your sitemap, and our guide to which pages to leave out of your sitemap explains why. Product photos want descriptive file names, and naming product photos at scale covers doing hundreds at once.

Meta descriptions and Product structured data

If your store reuses the opening of the description as the meta description, Google says there is no limit on how long a meta description can be, but the snippet is "truncated in Google Search results as needed, typically to fit the device width". So put the point first. For large catalogues, the same page says programmatic generation of meta descriptions "can be appropriate and are encouraged", as long as they stay human-readable and differ from page to page.

For Product structured data, Google's merchant listing documentation requires name, image and offers, and says the description "is not mandatory" but "strongly recommended". Grigora's free Product Schema Checker checks that set in your browser, along with price format, currency codes and GTIN check digits. A missing description comes back as a warning, not an error, which matches Google's wording.

Product description character limits on Google Shopping, Meta and WooCommerce

The same text rarely stays on your product page. It goes into a shopping feed, a social catalogue, structured data and, on WooCommerce, a summary block, and each sets its own rule. Only the store template counts words; the rest count characters or set no limit at all.

Google Shopping

Google's product data specification caps the description at 5,000 characters, asks that it match the description on your landing page, and rules out promotional text such as "free shipping", all capital letters, links to your store and details about competitors. Line breaks, lists and italics are allowed. Copy written like an advert breaks those rules at any length.

If you generate descriptions with AI, Google wants them in a different attribute. Its guidance on AI-generated content says they must go in structured_description, with the digital source type set to trained_algorithmic_media, instead of the plain description attribute.

Before you submit, run the file through the free Product Feed Validator. It reads CSV, TSV or XML in your browser, so nothing is uploaded, and checks it against Merchant Center rules, including the 5,000-character description limit, the 150-character title limit and GTIN check digits. It checks Google's rules, not Meta's.

Meta catalogues

Meta's commerce catalogue takes up to 9,999 characters in plain text, with no HTML, no links, nothing in all capitals, and a description that differs from the title. No sensible description comes near that ceiling, so the rules that matter are plain text and no links: a description exported with its HTML still in it breaks the first.

Write to the tightest slot, not the biggest

WooCommerce shows why. When a product has no short description, the original Product Summary block falls back to the full description and cuts it at 55 words, mid-sentence if need be. It applies the same 55-word cut to a short description that runs longer. WooCommerce rebuilt the block with a setting from 0 to 200 words, where 0 means no cut, and shipped it in version 9.6 on 20 January 2025. It did not swap the new block into existing Single Product templates, so check which one yours uses.

The fix works on every platform. Put the details that decide a sale in the first two or three sentences, and write a 20 to 40 word short description yourself. Then every slot, from Merchant Center's first 160 characters to a 55-word cut, starts with something complete.

Do shoppers read long product descriptions?

Mostly they skim. Nielsen Norman Group's analysis of real browsing data estimated that users read about 20% of the text on the average page, and that "users read half the information only on those pages with 111 words or less". The data is a 2008 study that logged 25 people's browsing, so treat it as a direction, not a dial.

The experiment usually cited for "cut your copy" advice is older still: Morkes and Nielsen, 1997. A version cut to about half the control's word count measured 58% higher usability. A scannable layout scored 47% higher, objective writing 27%, and all three together 124%. Cutting was the biggest single lever, yet it delivered less than half of what the three did together. That part tends to get dropped.

On product pages, Nielsen Norman Group reported in August 2014 that users skim text when reading online, reading more at the beginning of the description than the end. In the same study, 20% of task failures, times somebody could not finish a purchase they were asked to make, came down to incomplete or unclear product information. People stop reading, and they also fail when the answer was never there.

So cutting is not automatically the fix. Baymard reported in March 2021 that 10% of the largest e-commerce sites fail to keep product descriptions consistently detailed, and argues for more detail under subsection headings grouped by feature. Its 2018 spec sheet research found 50% of sites have spec sheets that are difficult to scan, and only 3% summarised the most critical specs at the top. Those sites have a shape problem, not a length problem.

How to structure a product description

Get the shape right and 400 words is easier to use than 150 in one unbroken paragraph. Four parts cover almost every product.

1. One promise, one line. What it is, who it is for, why this one. Nielsen Norman Group is blunt about the opening: "Don't waste the first few lines of product descriptions on text that doesn't help the user understand the product." "Crafted with care since 1998" spends the lines most likely to be read.
2. Three to five highlights. The decisions a buyer is actually making, such as size, fit, material or what is in the box. One line each, facts rather than adjectives.
3. A grouped spec block. Baymard's example of a spec sheet long enough to need labelled sub-sections is anything more than 20 specs. On a sheet longer than two screens, Baymard also suggests a short summary of the key specs on top.
4. An FAQ for everything else. Delivery, returns, care, the odd compatibility question. Our guide to how many questions an FAQ page should have covers the count and the markup.

The FAQ is the real answer to most length questions. Descriptions run long because they carry questions that belong somewhere else. Move those into the FAQ and the description shrinks without losing a fact.

How to work out the right length for your product

Measure instead of guessing. Run this on one product, repeat it across a category, and you have a house standard.

1. List the questions from real sources. Support email, chat transcripts and return reasons, not guesses. A return is a question somebody paid to have answered too late.
2. Answer each one in a sentence. No linking phrases yet. The draft's length is now set by evidence, not by a target.
3. Delete anything true of every product in the category. "Made from high-quality materials" is equally true of your competitors' products, so it tells the buyer nothing.
4. Benchmark against real product pages. Run three competitors' pages for the same kind of product through the free Page Word Count Checker. It counts the body text, leaving out navigation and scripts, so the total covers more than the description. Read it as an upper bound.
5. Check the sentences, not just the total. Paste your draft into the free Readability Score Checker for a Flesch Reading Ease score, a grade level and the average sentence length.

Long descriptions often fail on sentence length before they fail on word count. A 480-word description built from 15-word sentences can read easily. The same 480 words in 25-word sentences is hard going, and a word counter will not tell you which one you wrote.

Statistics to check before you quote them

Three claims get repeated around this question. None of them holds up as quoted.

• "40% of returns are caused by bad product descriptions." The source is a Shotfarm survey of 1,542 consumers, released on 28 October 2015, and it says something narrower: 40% of shoppers had returned an online purchase in the past year because of poor product content. A share of shoppers is not a share of returns. The same release found 86% unlikely to buy again from a retailer that gave inaccurate product information.
• "Cutting text by 54% improves comprehension." This traces to a 1998 Nielsen Norman Group rewrite of two Sun white papers, where the new version was 54% of the original length, a cut of 46%. Its headline figure is a usability score combining task time, errors, memory and satisfaction, not comprehension, and the rewrite also added headings and bullets, dropped the marketing language and split three pages into eight. The 159% gain belongs to all of it.
• "Write at least 300 words for SEO, and never more than 600." Both halves circulate on copywriting blogs with nothing underneath them. Google has no preferred word count, no platform publishes a 600-word rule, and the feed limits above are set in characters.

Writing product descriptions in Grigora Commerce

Grigora Commerce has no field called description. A product starts with a Product name and a Product promise, which explains what the customer receives, who the product is for and why they should buy it. Highlights and FAQs follow: short points to scan, then answers about usage, delivery and access. That is three of the four parts above built into the form; specs go in the highlights or the FAQs.

The same product form holds the SEO title, meta description, canonical URL and search visibility, so page copy and search copy get written in one sitting. See what Grigora Commerce covers, or compare plans: the trial runs 14 days and needs no card.
