What a good description has to do
Whoever reads the description is already interested: they have seen the photo and the price and want to know if the product works for them. The description has to answer that. What it is for, who it is for, what sets it apart from similar products, what dimensions or materials it has, how to use or care for it and what happens if they are not happy with it.
Before writing, gather your customers' real questions: the ones that arrive by email, chat or social media, the ones that appear in reviews and the reasons for returns. That list is the best content guide you will ever have, and it almost never matches what the supplier's sheet says.
A structure that reads well on mobile
On mobile nobody reads a long block of text. What works better is an opening sentence summarizing the main benefit, a short list of key points and then the detail organized in collapsible tabs (features, dimensions, materials, shipping and returns). That way people in a hurry see the essentials and those who need more information find it without searching.
- Opening sentence with the main benefit and who it is for
- Three to five key points, concrete and verifiable
- Collapsible tabs with features, dimensions and care
- Shipping and returns information near the buy button
Benefits backed by facts, not adjectives
“High-quality material” convinces nobody. “180 gsm organic cotton, not see-through in light colors” does. Every claim in the description should be verifiable or easy to picture. If you say something is comfortable, explain why: the fabric, the cut, the weight.
Write with a specific customer in mind and the way they talk. If your audience uses a certain word for the product, use that word even if you call it something else internally. This helps conversion and also rankings, because it is the word they type into Google.
Separate technical data into metafields
Dimensions, materials, composition, care instructions, compatibility or size charts should not be mixed into the description field. With product metafields you store them as structured data and the theme shows them in the right block, with the same format across the whole catalog.
The benefits are practical: you can bulk edit, use them as filters in Search & Discovery, reuse them in comparisons and translate them with Translate & Adapt without touching the main text. For information shared by many products, such as a size guide or the care instructions for a material, metaobjects avoid repeating the same text on every product page.
If you assign Shopify's standard product category, metafield-based product attributes are created (color, material, size, etc.) that also work for filtering and for sales channels.
Product page SEO
Each product has its page title, meta description and URL in the admin's SEO section. The page title usually works well with the product name and its differentiating attribute (material, use, model). The meta description does not directly affect ranking, but it does affect clicks: say what it is and why to choose it.
The biggest SEO problem in descriptions is duplicate content: the same supplier text used by dozens of stores, or the same description copied across variants turned into separate products. Google tends to show only one version and it is usually not yours. Rewriting the descriptions of your best-selling products is one of the SEO improvements with the best return.
Using Shopify's AI with judgment
The Shopify admin includes an AI assistant, Sidekick, that can generate product descriptions from the product editor itself. It is useful for a first draft or for large catalogs with little content, but Shopify itself warns that results may contain errors.
Use it as a starting point and always review the technical data, tone and claims. An unreviewed generated description tends to look like any other store's, which is exactly the opposite of what you need to stand out and rank.
How to prioritize if you have many products
You do not need to rewrite the whole catalog at once. Start with your best sellers and with the products that get many visits but convert poorly: that is where every improvement shows. Then create a description template per product type and apply it to the rest gradually.
Measure before and after with Shopify reports or GA4: add-to-cart rate, product page conversion and questions received about that product. If email questions drop, the description is doing its job.
If you sell in several languages, do not translate descriptions word for word. With Translate & Adapt you can start from a machine translation and then review it, but you should adapt units, sizes and expressions to each market. What people search one way in Spain may be searched with a different word in another country, and the description should use the one local customers use.
And decide who keeps descriptions up to date. When a material, a dimension or the returns policy changes, the text has to change too. Having that data in metafields and metaobjects makes the job much easier, because it is updated in one place and reflected across the whole catalog.
Frequently asked questions
How long should a product description be?
As long as it takes to answer the customer's questions. A simple product may need little text; a technical or expensive one, much more. What matters is that it is organized and reads well on mobile.
Can I use the supplier's description?
You can as a base, but if other stores use it too, Google will tend to show only one version. Rewrite it at least for the products that matter most to you.
Where do I put dimensions and materials?
In product metafields. That way they always display the same way, can be used as filters and can be bulk edited without touching the main description.
Can I generate descriptions with AI in Shopify?
Yes, the Sidekick assistant in the admin generates descriptions from the product editor. Always review the result, because it may contain errors and tends to be generic.
