What Is a Personalization Engine?

When it comes to online shopping, a personalization engine is a tool that companies use to track and analyze customer activity. Its main point is to provide a more personalized service, like targeted promotions, product suggestions, and other automated marketing efforts. 

Digital marketing teams use content personalization engines because they increase the number of leads that turn into customers, improve marketing campaigns, and increase customer satisfaction. And all this greatly improves corporate results. Digital customer experience delivery platforms (DCED) and customer data platforms (CDP) sometimes have personalization engines built in or integrated. The tools use a personalization engine and A/B testing software to make the content creation and distribution cycle to be fully customizable.

Also, a customization engine must meet the following requirements for a product:

  • Combine the information gathered from the different customer service channels;
  • Create and offer different user experiences for each channel;
  • Provide customers the option to customize their purchases on their own;
  • In the process of developing your client profile, you should make use of A/B testing, segmentation, and machine learning;
