Usually product reviews are displayed on the product detail pages of online shops. Here you have a high information content. For the customer it is about a concrete product, about which he wants to inform himself as comprehensively as possible. Category pages, however, already contain some individual products for which the average rating of the product should already be presented here. Thus the potential customer can make himself fast a first picture of it, how other customers estimate the respective product.
On the category side or in product lists product reviews have other tasks than on the product detail side. On the product detail page they influence the purchase decision. On the category page, they primarily influence which products customers look at more closely in detail.
