What is implicit data?
Say, for instance, your co-worker says, “Fido hurt his paw playing fetch yesterday. I need to take him to the vet this afternoon.” The explicit data given is that Fido was hurt and is going to the vet. The implicit data is that Fido is a dog.
How is implicit data collected?
Hidden fields are also an effective way to collect implicit data. These are form fields that you choose to add that aren't visible to the user. Once the fields are added, the information is simply collected in the background.
The last critical example of implicit data is the coupon code. If you know exactly which campaigns or which coupon codes a customer has signed up for, that will help you target them with different types of offers or communication. For example, if a segment of users has already taken advantage free shipping, perhaps you want to offer them a 10% off coupon instead.
