In both the B2B and B2C fields, knowing how to define which KPIs to monitor for each phase of our lead's buyer journey will give us the ability to make informed decisions based on objective numbers, minimizing the risk of incurring cognitive biases.

In order to explain a phenomenon in its entirety, it will be necessary to analyze the data in a systemic way, keeping in mind the specific purpose and the context of reference in which each KPI is observed, since, if taken individually, they risk providing a distorted vision of reality.
For example, CTR or CPC may be relevant KPIs for evaluating the effectiveness of an ad but, if disconnected from the quality of the leads generated, they will only give us a partial vision of reality, suggesting a potentially wrong direction.
This article will provide a list of some of the key KPIs to monitor at each stage of a lead's lifecycle, from the moment they land on our website to the end of the sales funnel.
