Targeted special strategies
In addition to the personalization options mentioned above, there are many other options available. Some of these include targeted recommendation strategies, which are used by babymarkt.de in more specific cases.
Sold-out product detail pages
Of course, it is generally best to avoid customers coming across sold-out products when searching. However, with very specific searches, it can happen that only a few products match the search query and sold-out products are displayed. Wish lists or external links may also cause customers to land directly on the product detail page of a product that is currently sold out. In order not to lose the shop customer in these cases, it is advisable to display a prominently placed alternatives widget on the PDP. This widget should present the shop visitor with the best possible alternative items for the desired product. By displaying alternatives that are very similar to the original product, the user is less likely to leave the site. Reminder options when the product becomes available can also prevent frustration and help to retain customers.

Series and outfits
Another specific example of recommendations are "products from the series." These are matching products that are in the same style and from the same brand. Such series widgets are not useful for all categories. However, they are particularly suitable for products in categories such as furniture, nutrition, or personal care. This allows customers to see that they can furnish an entire room with products from the same series, for example, furniture. This confirms their choice and makes the decision easier. It also allows the shop's product range to be presented.
Outfit widgets in the fashion sector are not necessarily tied to brands or series/collections, but can still be linked to them. Here, clothing items that match the product shown and complete the outfit should be presented. Color and size availability should be taken into account. Customers can add the products shown in the recommendation widget directly to their shopping cart or save them to their wish list.
