How do I write effective custom AI prompts?
The custom instructions field lets you give the AI your own rules for how it writes your listings. It applies to the title as well as the description, not just the tone.
Where to find it
- Shopify and Wix apps: Import options → Content tab → open Advanced at the bottom → Extra instructions (tone, wording, rules)
- Web dashboard: Settings → Products → Custom AI instructions
What you can put in it
Anything you would tell a copywriter: structure, wording rules, words to avoid, things to always include.
Write in British English. Never use the word "premium".Always name the material and the room it suits.Do not mention LED, dimmable or wattage unless the supplier page says so.Translate all content to French
Long, detailed rulesets work well here, including a full house style with its own worked examples. Where your instructions and our built-in rules disagree, yours win.
If you only want a title format
You do not need a prompt for this. Paste two or three of your own titles instead:
- Shopify and Wix apps: Content tab → Title card → set it to Rewrite → Add title examples to guide formatting
- Web dashboard: Settings → Products → Customize product title format
Give it at least two examples. With only one, the AI reads the whole line as fixed text and every product can come out with that same title.
If you want to change the description structure
Which sections appear, their order and their headings are not set by the prompt. They come from the layout editor: Content tab → Description card → set it to Rewrite → open the layout editor underneath. The writing tone lives in there too.
