What listing images should prioritize
The main image identifies the product. Supporting images then explain the strongest benefits, product details, dimensions, compatibility, use cases, comparison and lifestyle outcome in a sequence that remains understandable at thumbnail and mobile size.
What A+ Content adds
Amazon describes A+ Content as enhanced product-page content using images, text, comparison charts and other modules. Basic and Premium formats have different capabilities and eligibility requirements, so the final module plan should match the seller account.
When to buy both
A combined system is useful for a new launch, an unfamiliar product, a product with several technical or material details, or a brand that needs consistent presentation above and below the fold.
What to avoid
Do not simply enlarge the listing images and call them A+. Repetition wastes the extra space. The A+ sequence should extend the decision path while remaining consistent with the listing.
