Most Shopify product descriptions are written like the merchant is afraid to leave anything out. Materials, dimensions, care instructions, brand history, founder story, sustainability statement, sizing notes, three paragraphs of vibe. By paragraph two the shopper has scrolled past the buy button.
The job of a product description is narrower than that. It needs to make a decision easier. Either the shopper buys, or they decide this product is not for them and leave. Both outcomes are fine. The bad outcome is the third one: they get confused, get bored, and never decide.
The first 50 words do almost all the work
Most shoppers read the first sentence and skim the rest. A few read more if the first sentence earned it. Almost none read everything.
The first 50 words should answer three questions, in this order:
- What is this thing?
- What is it for?
- Why is it good?
Not in three separate sentences. Woven together, in one or two opening lines.
A bad opener:
Welcome to our store. We are excited to introduce the latest addition to our collection. This product was carefully designed with you in mind.
That’s 28 words and they say nothing. The shopper doesn’t know what the product is, doesn’t know what it does, and has no reason to keep reading.
A working opener:
Heavyweight 14-ounce cotton hoodie cut for layering, with a kangaroo pocket and a lined hood. Made in Portugal, designed for daily wear in cool weather.
Same word count, completely different page. The shopper knows what they’re looking at, what it’s for, and has at least one specific signal of quality. From here they decide whether to keep reading.
Structure that converts
After the opener, the rest of the description should follow a predictable shape so shoppers can find what they need without reading everything.
A pattern that works for most product categories:
One opener paragraph (the 50 words above).
Three to five bullet points of concrete features. Material, dimensions, what makes it different from the cheaper version. Skip the obvious. Don’t write “made of fabric” for a hoodie.
One paragraph of context if it adds something. Where it’s made, who made it, what occasion it’s designed for. This is where voice happens. Skip it if you have nothing real to say.
A specifications block at the bottom for shoppers who want exact numbers. Care, dimensions, weight, country of origin, model details if relevant.
That’s it. Most product descriptions should be under 200 words total. Some categories (technical gear, beauty, supplements) need more. Most don’t.
What to cut
A non-exhaustive list of things almost every Shopify description should remove:
- Generic openers. “Welcome to our store”, “Introducing”, “We are excited to share”.
- Marketing adjectives that don’t carry information. “Premium quality”, “luxurious”, “exceptional”, “unmatched”. They are unprovable and shoppers tune them out.
- Brand backstory inside the product description. Put it on an About page. The product description is not where to discover that your great-grandmother founded the company in 1923.
- Generic statements that apply to any product in the category. “Perfect for everyday wear” describes 90% of all clothing.
- Repeated product name. “The Classic Black Cotton Hoodie is a black cotton hoodie that…” Skip the restatement; the title is already on the page.
The test: if you can copy a sentence from your description, paste it into a competitor’s product description, and it would fit equally well, the sentence has no information and should go.
Brand voice without padding
Voice is the part of the description that sounds like you, not like a generic ecommerce store. It matters because it’s how a shopper decides whether they trust the brand. But voice gets confused with verbosity, and the result is a wall of voice and no substance.
A useful rule: voice is allowed to add about 10–20% of total word count. Not more. The voice is in the verbs, the specifics, the asides. It’s not in extra paragraphs about how the product was lovingly crafted.
Three voices, same product (a 14-ounce cotton hoodie):
Professional: “Heavyweight 14oz cotton hoodie. Kangaroo pocket, lined hood. Manufactured in Portugal.”
Casual: “Thick enough to be your only layer in autumn. Big kangaroo pocket for your hands. Made in Portugal because the factory there does it right.”
Playful: “A 14oz hoodie that takes itself seriously about staying warm. Pocket for your hands, hood for your ears, and a fit that doesn’t quit after three washes. Made in Portugal.”
Each one carries the same product information. Each one sounds different. None of them are 400 words.
The bulk problem
A typical Shopify store has 50 to 500 products. Writing 200 words of working description per product, by hand, takes 15 to 30 minutes each. For a 200-product catalog, that’s roughly 60 hours of writing work. Most merchants do not have 60 hours.
The two real options:
- Hire a copywriter. Quality if you hire well. Slow and expensive. Roughly $20–80 per product at agency rates.
- Generate with AI, then edit. Faster, cheaper, the quality is now reliably good when the model has access to the product’s images and existing data. The edit step is critical (we cover this in AI product descriptions: when they help and when they hurt, drafted for next month).
What does not work is leaving the description empty, or pasting the manufacturer’s spec sheet, or filling it with the marketing adjectives we listed above. Each of those is worse than a short, honest description.
The conversion math
To make this concrete: a typical Shopify product description rewrite, done well, lifts conversion rate on that product by 5–15%. The bigger lifts come from products that had genuinely bad descriptions to start with. A store doing $50k a month with a 200-product catalog and median-bad descriptions can usually find an extra $2,500–7,500 a month from a description rewrite alone. The first 20 products by revenue carry most of the upside.
