Introduction
Personalization Engines are software platforms that use data, AI, and machine learning to deliver tailored experiences to individual users across websites, apps, and digital channels. Instead of showing the same content to everyone, these tools dynamically adjust content, recommendations, and offers based on user behavior, preferences, and context.
In simple terms, personalization engines help businesses show the right content to the right user at the right time.
