Why bother with product descriptions in 2025?

Good copy still sells. Shoppers skim fast. Search engines rank pages on words they can parse. A fresh survey of ecommerce SEOs put "listing and descriptions" at the top of five AI use cases. If you skip this copy, you leave money on the table.

Why stores move from outsourcing to ChatGPT

One entrepreneur at a growing online brand explains it plain: paying freelancers felt slow and pricey, so the team tried ChatGPT and got copy "in‑house, faster, and cheaper". Similar stories repeat across small shops and big brands. A University of St Andrews study of almost 10,000 UK SMEs found AI can lift productivity by 27‑133%.

What ChatGPT does well for product pages

  • Speed. It drafts a 150‑word blurb in seconds.
  • Consistency. Tone stays the same across 1,000 SKUs.
  • Multilingual output. Handy for cross‑border sales .
  • SEO‑aware suggestions. It can weave in keywords you list.
  • Built‑in inside many tools. Shopify Magic now writes copy right inside the admin .

Step‑by‑step guide

1. Collect the raw facts

Throw specs, size, materials, care tips, and a short note on brand tone into a simple doc.

2. Craft a short prompt

Write a friendly, benefit‑first product description.
Use these facts: .
Tone: playful but clear. 120 words max.

3. Iterate in batches

Push 20 SKUs, skim results, change the prompt once, rerun. Small tweaks — like moving benefits to the first line — add up.

4. Check SEO

Run the text through your favorite on‑page checker. Feed missing keywords back into ChatGPT.

Advanced moves

Variant testing. Ask for three tones, then A/B test click‑through. Personalisation. Pass user segments (e.g. "new parent", "outdoor hobbyist") into the prompt to serve changing copy on the fly — Shopify and BigCommerce apps now allow it. Structured output. Request JSON so your dev team can slot copy into CMS fields without manual paste.

Limits and safe guards

  • Fact‑check every technical claim. AI can slip.
  • Keep regulated claims (health, finance) for human writers.
  • Store customer data off the prompt to avoid leaks.
  • Watch Google’s guidance on "low‑effort content" . Always add real value.

ROI quick math

A freelance copywriter may charge $40 per SKU. ChatGPT API usage for ~250 words is under $0.02. Even adding 10 minutes of staff polish, the saving per 500 SKUs lands north of four figures.

Key takeaways

  1. Start small — five SKUs, one prompt, tighten fast.
  2. Use brand voice docs so tone stays tight.
  3. Edit, always. Human eyes keep trust.
  4. Track conversion uplift. Let data prove the value.
