Big online stores are no longer just showing ads. They are becoming content creators too.

New reports from the US show that companies like Amazon and Walmart are building more of their own content such as videos, guides, and product stories right inside their shopping platforms. The goal is simple: keep shoppers on the page longer and turn that attention into sales.

This is a big shift. For years, “content marketing” mostly happened on brand websites, blogs, and social media. Now, a growing part of that content is moving to retail media networks where the ad and content systems run by large retailers themselves.

Why does this matter for brands? Because attention is limited, and shoppers are increasingly making decisions inside the store, not before they get there. If a retailer’s own content is answering a shopper’s questions and closing the sale, brands need to think differently about where their story gets told and how it performs.

At the core, this is not really a fight between “ads” and “content.” It’s a sign that performance and storytelling are merging into one thing. Brands that treat their content as just another marketing checkbox will lose ground to brands that treat it as a real growth engine that is built with data, tested for results, and placed where buyers actually are.

For businesses building their digital presence, the lesson is clear: content can’t just look good, it has to work hard. Every page, video, or product story should be built with a purpose to rank, to convert, and to grow revenue, not just to exist. As retail media keeps expanding, brands that combine strong creative with strong data will be the ones that turn attention into real, measurable growth.
