Draft a homepage banner brief with clear messaging

The homepage hero carries several messages at once, and the offer terms get cut off on smaller screens. In this case, the immediate task is to draft a homepage banner brief with clear messaging. The workflow should produce banner briefs and size variants listing every variant with its placement and file constraints.

A prompt you can drop directly into Spark

First replace every [bracketed] placeholder with real store scope and constraints, then add any actual records or data you have, and paste it into your preferred AI assistant or Spark agent. Spark will follow this page's workflow to produce structured output and verification steps.

ai-prompt.txt
Act as a Shopify operations specialist.
Help me draft a homepage banner brief with clear messaging.
My store context is [describe the business, products and target audience].

My scope is [specify the affected products, pages, customers or reporting period]. Use these inputs: [homepage section dimensions, the current hero asset, headline and supporting copy with character limits, the offer terms that must stay visible, and the crops applied at each breakpoint]. Rank the message into one claim, one supporting line and the offer terms, test that order against every required crop, and hold back any version where the terms or the call to action fall outside the visible area.
Return banner briefs and size variants listing every variant with its placement and file constraints for the specified task.
Show the relevant evidence or before-and-after examples and explain how I can verify the result.
If essential data is missing, ask for it and mark unsupported conclusions as unknown.
Do not invent metrics, product claims or customer facts.
For any publication, message, account or store change, use only connected tools within my explicitly authorized scope and report success only after verification; otherwise provide the draft or proposed steps.

How to solve

A recommended resolution workflow

Split the work into input, judgment, and deliverable phases. Verify each step's output before moving to the next.

01

Step 1

Collect the section dimensions the homepage theme uses, the current hero asset and its file name, the headline and supporting copy with their character limits, the offer terms that must remain visible, and the crops the theme applies at each breakpoint.

02

Step 2

Rank the message into one claim, one supporting line and the offer terms, test that order against every required crop, and hold back any version where the terms or the call to action fall outside the visible area.

03

Step 3

Deliver the banner brief with a variant table naming each file's placement, dimensions and file constraints, mark the crop where the message hierarchy fails, and confirm no variant drops the offer terms before it ships.

FAQ

Common questions when running this scenario

Cover decision rules, frequent misunderstandings, and required inputs so the team aligns on prerequisites before execution.

Where do the offer terms belong in the hierarchy?

Directly beneath the supporting line and inside the safe area of the smallest crop, because terms that appear only on the desktop variant are exactly the ones shoppers on smaller screens never see.

How is the headline length decided?

By the character limit the section documents and by the narrowest crop, so a headline is shortened when it wraps or collides with the supporting line rather than shrunk until it can no longer be read.

What proves the brief is publishable?

Every listed variant has a placement, a dimension set and a file that meets the constraints, and the smallest variant still shows the full message hierarchy without asking the visitor to click further.
