While AI is having significant impact with the consumer market -- witness the explosion of AI-driven bots and digital assistants -- businesses are realizing the important ways they can take advantage of AI. One of the biggest areas of growth is in AI Marketing (AIM). Start with the fact that computers are great at crunching numbers, quickly providing results from complex math formulas, and handling repetitive tasks without complaint. Add in software that uses well-designed machine-learning algorithms, and you have the potential of a powerful AIM process to deliver detailed analytics and offer valuable insights. AIM software will revolutionize the role of the marketer -- for the better.
