#4 Personalization in relation to the referrer
As already explained, personalization can be based on characteristics and data that are available to you thanks to the latest technologies. In addition to the location of the shop visitor, for example, the characteristics also include the source—the so-called referrer.
The referrer provides information about the origin of a website or shop visitor. It therefore refers to the source through which a customer arrived at the shop. In most cases, this is a URL. With the help of the referrer, evaluations can be made about the origin of visitors, which plays an important role in online marketing in the field of web analysis, among other things.
The referrer can also be used for personalization. This allows the page accessed and its content to be customized depending on the source or origin of the customer, such as Google Shopping, social media, etc. For example, if a customer arrives directly at the corresponding product detail page via a Google ad for a specific product, you can customize the content. This page is therefore different from the product detail page that a customer sees when they are already on the site and access it from your shop.
It makes sense to take special measures here, as the display of Google ads is also associated with a high budget. You should therefore ensure that visitors do not immediately leave your shop after visiting it. Possible ways of personalizing your shop include displaying specific recommendations and integrating a search widget with tiles and filter options. This allows you to keep customers in your shop, as they can easily navigate further within the shop from this page.
