A comparison image should not become a spreadsheet with product photos attached.
It should answer one buyer decision.
Examples:
which size should I buy?
which bundle includes the accessory?
which model fits travel?
which variant has the finish I want?
which product has the feature I care about?
That is the work.
My checklist before making one
I would define these items before generating or designing the image:
product category
compared options
buyer decision
product facts that cannot change
allowed labels
banned additions
final channel
mobile crop
The product facts matter most.
For a bottle, protect cap shape, logo position, color, material, and height.
For a bag, protect pocket layout, straps, zipper position, and hardware.
For skincare, protect label, cap, liquid color, package size, and kit contents.
For electronics, protect ports, connectors, included cables, and device fit.
Useful comparison formats
I usually like five formats:
size comparison
bundle comparison
variant comparison
feature comparison
use-case comparison
Each one should stay narrow.
A size image should show size.
A bundle image should show what ships in the box.
A feature image should show the real part that supports the claim.
The more claims you put in one image, the harder it becomes to review.
The AI prompt should be boring
For comparison images, boring is often safer.
Example:
Create an ecommerce product comparison image from these product references. Show three variants side by side at the same camera angle. Keep product shape, label, color, cap, material, and proportions unchanged. Add short labels only. Do not add accessories, badges, fake features, extra packaging, platform logos, or long text.
The goal is product proof. The prompt should protect the real SKU instead of creating a more attractive product than the one that ships.
Final QA
Before publishing, I would check:
are all products scaled correctly?
did the AI add any accessory?
did the label change?
did the color shift?
are claims supported by real product data?
can the image be read on mobile?
does the image compare two or three options, not too many?
would a buyer expect something that is not included?
If any answer feels uncertain, the image should be revised.
