The way to get useful e-commerce results from an AI assistant such as ChatGPT or Claude is to write your prompt like a job brief: give the model a role, define the task clearly, add context about your product and customer, and specify the format and limits you want. A short prompt like "write a description for this product" produces copy that sounds like everyone else's; a prompt that includes your brand voice, target audience and the product's real features gives you a draft you can use straight away.
In this article we share the structure of an effective prompt and examples an e-commerce team can use every day: product descriptions, category copy, campaign emails, ad copy and customer service replies.
The 6 parts of a good ChatGPT or Claude prompt
Not every prompt needs all six, but the more you include, the better the result:
Role: the expertise the model should write with, such as "As an experienced e-commerce copywriter".
Task: what you want, in one clear sentence.
Context: information about the product, brand, target audience and sales channel.
Format: length, heading structure, number of bullet points, tone.
Constraints: words to avoid, exaggerated claims, legal limits.
Example: a sample text you like. The model imitates its tone and structure.
The difference between a vague and an effective prompt
Vague prompt: "Write a product description for this T-shirt."
Effective prompt: "As an experienced fashion e-commerce copywriter, write a product description for women aged 25-35 looking for simple, high-quality basics. Product: 100% organic cotton, oversized fit, 5 colour options, made in Turkey. Tone: friendly but understated. Format: 2 short paragraphs followed by a 4-point feature list. Don't use words like 'perfect', 'unique' or 'flawless'."
The second prompt tells the model who it's writing for, what to say and which limits to stay within. The result is correspondingly ready to use.
7 prompt examples for e-commerce
1. Product description
"Our brand [brand name] sells [product category] for [target audience]. Our brand voice is [friendly / premium / technical]. Based on the product information below, write a 120-150 word product description. First describe the benefit the product brings the customer, then list the technical features as bullet points. Don't add any feature that isn't in the information. Product information: [features, materials, dimensions]."
The last sentence matters: it stops the model from adding features the product doesn't have.
2. Category page copy
"Write a 250-word SEO text for the [category name] category page. Main keyword: [keyword]. The text should help visitors decide which product to choose in this category: describe product types, uses and what to look for when choosing. Use the keyword naturally 2-3 times. Add a short 3-question FAQ at the end."
3. Meta title and description
"Suggest 3 different meta titles (max 60 characters) and 3 different meta descriptions (max 155 characters) for the page below. Each should include [keyword]. The descriptions should contain a concrete benefit that encourages users to click. Page content: [text]."
4. Campaign email
"Write an email for [campaign name]. Discount: [rate / condition]. Valid: [dates]. Audience: customers who have bought in the last 6 months. Suggest 5 different subject lines (max 45 characters), then write an email body of no more than 100 words with a single clear CTA. Create urgency, but don't use misleading wording."
5. Ad copy variations
"Write 5 different primary texts for Meta ads promoting [product]. Each should take a different angle: benefit, social proof, problem-solution, price-value and curiosity. Each text should be no more than 125 characters. Then suggest a headline of up to 40 characters for each."
6. Customer service reply
"A customer is complaining that their order is late. Their message: [customer message]. Shipping status: [information]. Write a reply of no more than 80 words that apologises, explains the situation clearly and offers a concrete next step. Tone: friendly and solution-focused. Don't promise a specific delivery date."
7. Analysing customer reviews
"Analyse the customer reviews below. List, under separate headings, the 3 most praised features, the 3 most common complaints and the questions that should be answered on the product page. Reviews: [reviews]."
This output is a good starting point for updating your product description and FAQ based on customers' real questions.
5 tactics for better results
Give your brand guidelines once. Prepare a short text covering tone, words to avoid and your target audience, and add it to the start of every prompt. You can make this permanent using the project and custom instruction features in ChatGPT and Claude.
Don't expect a perfect result first time. Improve the first output with feedback such as "make it shorter" or "make the second paragraph more concrete".
Ask for several options. Especially for headlines, subject lines and ad copy, asking for 5-10 options and choosing the best is more efficient.
Ask the model to ask questions. Adding "If any information is missing, ask me before you start" to the end of your prompt stops gaps being filled with guesses.
Be specific about format. Saying "no more than 80 words" instead of "keep it short", or "4 bullet points" instead of "in bullet points", gives more consistent results.
ChatGPT or Claude?
The prompt structure and examples in this article work the same way not only in ChatGPT but also in Claude, developed by Anthropic, and in other AI assistants. The principle of role, task, context, format and constraints is independent of the tool.
When choosing between the two, consider the following:
Working with long documents: if you want to give long texts such as a product catalogue, long lists of customer reviews or your brand guidelines in one go, try the document upload features both tools support.
Writing tone: the most practical method is to try the same prompt in both tools and pick the one closer to your brand voice. The tools' writing styles differ.
Persistent instructions: ChatGPT's custom instructions and projects and Claude's projects let you use your brand guidelines without retyping them in every chat.
Team use and data policy: whether data is used to train the model on business accounts, and team management features, vary from tool to tool; check these terms before using them across your company.
In practice, many teams use both tools together: one to generate ideas quickly and the other to edit the text. What matters is not the tool but the quality of the prompt and the output going through human editing.
What to watch out for
Verify product information. The model can produce fluent text even on topics it isn't sure about. Always check details such as materials, dimensions, ingredients and warranty before publishing.
Be careful with legal wording. Health claims, comparative phrases such as "cheapest" and discount conditions must comply with consumer law.
Don't share customer data. Before uploading personal data such as names, phone numbers or addresses to AI tools, assess it under KVKK, Turkey's data protection law; anonymise the data where possible.
Don't write everything to the same template. Publishing hundreds of product descriptions with the same prompt and no editing creates pages that look very similar. That's a risk for both SEO and customer experience.

Shopify's own AI tools
If you have a Shopify store, you may not even need to switch to an external AI tool for some tasks. Sidekick, the AI assistant built into the Shopify admin, and Shopify Magic can write product descriptions, suggest email subject lines and interpret your store data directly in the admin. We cover Shopify's latest AI features in our article on Shopify Winter '26.
Frequently asked questions
Do product descriptions written with ChatGPT hurt SEO?
Not on their own. But unedited descriptions that look very similar and contain no product-specific information neither persuade customers nor perform well in search engines. Enrich every description with product-specific details.
What's the best prompt length for ChatGPT?
There's no fixed length. What matters is that the role, task, context, format and constraints are clear. For e-commerce tasks, prompts of 3-6 sentences usually work well.
Should I write prompts in Turkish?
If you want Turkish copy, writing the prompt in Turkish usually gives more natural results. It also helps to state the output language separately at the end of the prompt.
Do these prompts work in Claude or Gemini too?
Yes. Prompt structure is independent of the tool; you can use the same examples in ChatGPT, Claude or Gemini. Since tone and length can differ slightly between tools, it's worth trying the same prompt in a few of them.
