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:
Vertical
– Use 1–2 broad terms (e.g. women’s activewear, organic skincare, home décor).Types of Products you'd like to see
– List 2–4 main product types or sub-genres (e.g. leggings, sports bras, hoodies).Persona
– Describe your target customer in a few words (e.g. budget-conscious millennials, luxury gift-givers, eco-friendly parents).Brand
– Name your own brand or the style you want to convey (e.g. Nordic minimalism, vintage boho, performance techwear).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.Keywords
– Provide guidance and examples of relevant keywords or phrases, separated by commas (e.g. moisturizer, SPF, vegan serum, anti-aging).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.

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

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.

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