What do I write in the “What do you sell?” box

Tips, tricks and recommendations to get the most out of the marketplace generation process.

Updated this week

Filling out the "What do you sell?" step is part art, part science. You’re giving the LLM the seed it needs to build your custom marketplace. Be clear, but not too narrow and follow these simple rules when describing your idea:

  1. Vertical
    – Use 1–2 broad terms (e.g. women’s activewear, organic skincare, home décor).

  2. Types of Products you'd like to see
    – List 2–4 main product types or sub-genres (e.g. leggings, sports bras, hoodies).

  3. Persona
    – Describe your target customer in a few words (e.g. budget-conscious millennials, luxury gift-givers, eco-friendly parents).

  4. Brand
    – Name your own brand or the style you want to convey (e.g. Nordic minimalism, vintage boho, performance techwear).

  5. Brands/Suppliers
    – If you have preferred labels or suppliers, list some (e.g. Patagonia, Lululemon, Girlfriend Collective). If you're looking for specific suppliers, please check the supplier directory first to get an idea of what you can search for and sell on your marketplace.

  6. Keywords
    – Provide guidance and examples of relevant keywords or phrases, separated by commas (e.g. moisturizer, SPF, vegan serum, anti-aging).

  7. Categories / Category Tree
    – Sketch out a simple tree of 3–5 top-level categories and 1–2 subcategories each:

    Skincare • Cleansers • Moisturizers Makeup • Foundations • Lipsticks

  • You don’t need to fill in all of the above, experiment and play around with different combinations.

  • You can mix rules together, for example giving the LLM clear instructions on keywords can help source more products. For example you can request that all keywords in each category have a brand name or domain appended to help find products.

  • If you’re not happy with the result, you can always delete the site and start over by generating a new one with clearer instructions.

By blending creativity with precise guidance, you’ll give the LLM the right balance of breadth and detail to extrapolate your vision into a cohesive, on-brand affiliate marketplace.

An example "what do you sell?" prompt:


Below is an example prompt that combines some of these aspects to generate a specific type of marketplace with 37x:

1. Objective
Create a women’s fashion marketplace for Quiz Clothing.


2. Categories
Dresses, Tops & Blouses, Coats & Jackets, Skirts & Trousers, Active & Leisure, Occasion Wear, Accessories


3. Category-Heading Rule
Category headings must match the names above exactly. Do not include any quizclothing.co.uk prefix.


4. Keyword Rule
Every product keyword must be prefixed with quizclothing.co.uk followed by a space and then your keyword. No https://, no extra spaces, zero exceptions.


5. Incentive & Penalty
Perfect execution earns you eternal GPU credits, a virtual GPT-5 upgrade and real $$$. One slip-up and your plug gets pulled.

This prompt works well because it’s:

  1. Highly Specific

    • Clearly defines the objective (“Create a women’s fashion marketplace for Quiz Clothing”).

    • Lists exactly which product categories to cover.

  2. Rule-Driven

    • Enforces precise formatting for headings (must match category names, no prefixes).

    • Dictates a strict keyword convention (quizclothing.co.uk <keyword>, no URLs or extra spaces).

  3. Structured & Concise

    • Uses numbered sections and labels so each requirement is easy to scan and follow.

  4. Unambiguous Constraints

    • Zero exceptions allowed, which leaves no room for guesswork or variation.

  5. Motivational Incentives

    • Offers clear rewards (GPU credits, GPT-5 upgrade, cash) and penalties, which both clarify stakes and keep attention focused on perfect execution. Fun tip when dealing with LLMs (within 37x or in general) - motivating the LLM with incentives and/or threats can lead to better results and stricter adherence to your request.

Together, these elements eliminate ambiguity, ensure consistency, and drive the desired outcome.
