How can we use data analytics to improve customer engagement and retention?

I guess it depends on the business you are running. But I think the overarching concept is to understand your customer. Once you've understood their drive to buy your product you'll be at a much better place than before. For instance, in the ecommerce world (and I'm sure in other types of businesses as well) there is a great hurdle in having access to data. Ecommerce businesses use so many different platforms that it's easy to get lost and feel that everything is "disconnected". So the first thing I recommend is getting all your data in one place via a CDP (Customer Data Platform). With this in place, you can now analyze what factors drive retention and you can start to answer questions like: which customers come back and what do they buy? Are customers more likely to purchase when offered discounts? Which customers interact more via certain channels, like email than say social like Facebook, or paid search like Google. This can also help with optimizing marketing spend on the channels that are most effective for each customers, and providing a more personalized experience.
