There are a lot of both CRM-platforms with the function of product recommendations and separate recommendation services. We will describe only the most interesting ones, in our view. Exponea
Mechanism of Exponea is, probably, one of the most comprehensive and interesting. On the web page there is a script installed which allows to analyze the behaviour of a user. The platform allows to track all the actions of a client, including, for example, offline purchases.
The recommendations themselves are based on the catalogues and can use any elements from them: products, promotions, articles and others. They are based on the four elements:
- The catalogue, which is the basis;
- The principle of choosing elements from the catalogue;
- Blacklist of the elements which should not be chosen (for example, goods which have already been purchased);
- Recommendations ranking principle (also based on the behavior of a use, for example, goods from a favourite category will be shown higher).
