How to use AI to write product descriptions for an Australian ecommerce store

Should you use AI to write product descriptions?

For most stores with more than a few dozen products, yes, with conditions. Product descriptions are one of the clearest cases where AI writing tools earn their keep: the task is repetitive, the structure repeats from product to product, and the backlog is usually large. Many stores still run on pasted supplier copy or a single sentence under a photo.

The conditions matter more than the tool. AI models are good at fluent, confident text and poor at knowing whether it is true. Ask one to describe a linen throw from its title alone and it will invent a thread count, a country of origin and a care instruction. Each invented detail is a potential return, complaint or misleading claim under Australian law. Treat AI as a fast drafting assistant working from verified inputs, not a copywriter that knows your products.

What can AI do well, and what should a human still own?

Separate language work from fact work. AI is strong at the first and unreliable at the second.

Task	Hand it to AI?	Why
Drafting a description from a verified fact sheet	Yes	Removes blank-page time and keeps structure consistent
Rewriting for length, tone or a different channel	Yes	Mechanical work that is quick to review
SEO titles and meta descriptions	Yes, with review	Formulaic, but check accuracy, length and the search term
Specifications, dimensions and materials	No	Must come from supplier data or your own measurements
Origin, safety, health or environmental claims	No	Carries legal risk and needs evidence you actually hold
Deciding what makes the product different	Human-led	Depends on knowing your customers, competitors and returns
Final approval to publish	Human only	Responsibility for the page sits with the business

Anything a customer could check, measure or rely on when deciding to buy should come from your own records, not the model. The same logic runs through our guide to which business tasks to automate first: automate the repetitive drafting, keep the judgement.

How do you set up an AI workflow for product descriptions?

The workflow that holds up is fact-first: facts are verified before any text is generated, so the model only ever rearranges true information into good sentences.

1. Build a fact sheet for each product

One spreadsheet row per product, with columns for everything a buyer needs: dimensions in centimetres, weight, materials, colours, what is in the box, care, compatibility, warranty, substantiated country of origin and delivery notes. Pull it from supplier specification sheets and your own measurements. The gaps you find are the same gaps that generate pre-sale emails.

2. Write one brief for voice and structure

One brief that every description follows, covering the customer, voice rules, a fixed structure and banned claims (detailed below). A fixed structure also speeds up review, because the reviewer always knows where to look.

3. Generate in small batches by category

Run one category at a time, ten to twenty products per batch. Products in a category share vocabulary and buyer questions, so outputs are more consistent, and problems with the brief show up while they are cheap to fix.

4. Fact-check every claim against the fact sheet

A reviewer reads each draft beside its fact sheet and checks every number, material, origin and performance statement. Anything not on the sheet is removed or verified. This step cannot be skipped.

5. Edit for genuine difference

AI drafts tend towards the average. The edit is where you add what only you know: why customers choose this product over the cheaper alternative, the question your team answers most often, the detail people mention in reviews. One or two specific, true sentences do more than a paragraph of polished adjectives.

6. Publish, measure and refine the brief

Publish, track how those pages perform, and feed what you learn back into the brief. Later batches need far less editing than the first.

What should an AI prompt for product descriptions include?

Output quality is mostly decided by the brief. A useful product description prompt has six parts:

• Role and audience. Who the description is for and what they care about, such as renters furnishing a small apartment.
• Voice rules. A few concrete instructions, such as plain English, short sentences, no exclamation marks and Australian spelling.
• Fixed structure. Two opening lines on what the product is and who it suits, three benefits each tied to a specific fact, a scannable specifications block, then care, delivery and returns notes.
• The fact sheet. The verified row for that product, pasted in full.
• Banned claims. No superlatives presented as fact, no environmental, health or origin claims unless they appear on the fact sheet, and no statements about refunds or warranties beyond the wording you supply.
• A rule for missing information. Instruct the model to write [CHECK] wherever a detail is needed but absent, rather than filling the gap.

That last rule is the most valuable line in the prompt: it turns the model's tendency to invent into a flag a reviewer can search for.

Will AI-written product descriptions hurt your SEO?

Not because they were written with AI. Google's published guidance on generative AI content focuses on whether content is helpful and original, not on how it was produced. What it warns against is generating large numbers of pages that add little value, which can fall under its spam policy on scaled content abuse. The practical catalogue risks are more ordinary:

• Duplicate supplier copy. If your text matches what every other stockist uses, search engines have little reason to prefer your page. Writing from a fact sheet solves this by default.
• Template sameness. A rigid prompt can make similar products indistinguishable. Vary the opening and benefits around what genuinely differs.
• Volume without review. Publishing hundreds of unchecked pages at once is close to the pattern the spam policy describes.

Used well, AI helps SEO. Feed it the words customers actually use, from reviews, support emails and search term reports, and the copy matches real searches. Our guide to keyword research for a small business covers finding those terms. Accuracy matters beyond your site too, because the same product data often feeds Google Shopping, where mismatches between page and feed are a common cause of disapproved products in Merchant Centre.

What does Australian Consumer Law mean for AI-written product copy?

The business publishing the description is responsible for it. Under the Australian Consumer Law, representations about a product must not be misleading or deceptive, and an AI tool drafting the words does not change who made the claim. AI drafts stray into the same risk areas, so focus review here:

• Invented specifications. Dimensions, materials, capacities or compatibility that are not on the fact sheet.
• Superlatives presented as fact. "The strongest" or "Australia's favourite" need substantiation. Remove them unless you have it.
• Origin claims. Phrases such as "Australian made" have specific meanings and should appear only when they are accurate for that product.
• Environmental claims. Words like "eco-friendly", "sustainable" or "biodegradable" are easy for a model to add and hard to substantiate; the ACCC has published guidance for businesses on environmental claims.
• Health and therapeutic claims. Health benefit claims can trigger separate therapeutic goods advertising rules overseen by the TGA.
• Refund and warranty wording. AI sometimes writes lines such as "no refunds on sale items", which can misrepresent customers' rights under the consumer guarantees. Those guarantees cannot be excluded.

Writing these rules into a short AI usage policy means everyone who touches the catalogue applies the same standard. This is general information, not legal advice; if your category has specific regulatory requirements, get advice on the claims you intend to make.

How do you measure whether AI product descriptions are working?

Treat the rollout as a test. Pick ten to twenty products in one category with steady traffic, record a baseline, replace the descriptions, and compare over an equal period. Four measures tell you most of what you need:

• Add-to-cart rate on the pilot pages, the most direct signal that the page persuades.
• Conversion rate from product page view to purchase, tracked by device.
• Returns marked "not as described", which show whether accuracy improved or slipped. Clear descriptions are one of the steadier ways of reducing return rates.
• Pre-sale questions about those products, from email, chat or phone. Fewer questions means the page is answering them.

Watch for promotions and seasonality distorting the comparison, and give organic search longer, since ranking changes in Search Console usually take weeks to show. If add-to-cart rate rises without returns rising, roll out category by category. For the product page fixes that sit alongside better copy, see our guide to improving product page conversion rate.

Where should you start?

Start with the fact sheet, not the AI tool. Take your highest-traffic category, build verified fact sheets for its top products, write a one-page brief, and run one batch through the full workflow, fact-check included. You will learn more from that batch than from comparing tools, and finish with a brief you can reuse. The goal is not speed for its own sake; it is a catalogue where every page is accurate, specific and useful to the person deciding whether to buy.
