## 1. What is a funnel in analytics?

**Answer**

A funnel is a sequential representation of the key steps users go through to achieve a given objective, such as a purchase or signup. Each step shows the number of users progressing to the next stage, making it possible to identify friction points and drop-offs. The term 'funnel' comes from the fact that the number of users naturally decreases at each successive step.

## 2. What is the typical order of steps in a classic e-commerce funnel?

**Answer**

A classic e-commerce funnel follows the purchase journey logic: the user visits the site, views a product, adds it to the cart, proceeds to the checkout page, then completes the purchase. This linear model helps identify where prospects drop off. The step between cart and payment typically has the highest abandonment rate, often related to shipping costs or an overly complex checkout process.

## 3. How to calculate the overall conversion rate of a funnel?

**Answer**

The overall funnel conversion rate is calculated by dividing the number of users who completed the last step by the number of users who entered the first step, multiplied by 100. For example, if 10,000 visitors land on the site and 200 purchase, the overall conversion rate is 2%. This rate provides a synthetic view of funnel performance but does not reveal where losses occur, hence the need to also analyze step-by-step rates.
