The first click model is a type of conversion attribution models that gives the conversion credit to the first touch point. Basically, this means that digital marketing channel to which a customer is exposed will also receive a credit for the conversion. Of course, this applies only to the channels that the customers actually interact with. The first click model is basically the same as the last click model when it comes to the so-called impulse buying. This is because the first click is at the same time the last click, as well. Because of its features, this model is often used by new brands, looking to spread the word about their product.
