The retailer's product page is your real landing page
More purchase decisions happen there than on anything a brand controls, and it is usually assembled from whatever was submitted years ago.
Marketplace and retailer listings carry the title, the images, the bullet points, the specifications and the reviews. That is the page where somebody decides.
Brands frequently submitted that content once, at onboarding, and have not looked at it since. Titles are truncated, images are outdated, and specifications are incomplete or wrong.
Auditing those listings across every channel is usually the highest-return conversion work available to a consumer goods brand, and it costs time rather than money.
Images do the most work. The number available, whether they show scale, whether they show the product in use, and whether they answer the question a shopper actually has.
Where platforms offer enhanced content, it is generally worth the effort, since it is one of the few places a brand can control the presentation inside somebody else's store.
