## Conversion computing metrics

### How Datadog computes conversion metrics
Consider a funnel with events `A → B → C` and event steps `A, A, A, B, C, C`.
Consider a funnel with events `A → B → C` and event steps **`A`**, `A`, `A`, **`B`**, **`C`**, `C`.

In this case, Datadog counts one conversion. This is because the conversion calculation matches only the first occurrence of event **A** and the first occurrence of event **C** in the sequence.
In this case, Datadog counts one conversion. Each occurrence of **A** is an entry that starts an independent attempt. Because all three attempts complete on the same **C** event, Datadog counts only the attempt with the earliest entry.

To further illustrate, if the user performs the event sequence `A, A, A, B, C, C, A, B, C`, Datadog counts two conversions. The first conversion completes with the sequence `A, A, A, B, C, C`, and the second conversion completes with the following sequence of `A, B, C`.
To further illustrate, if the user performs the event sequence **`A`**, `A`, `A`, **`B`**, **`C`**, `C`, **`A`**, **`B`**, **`C`**, Datadog counts two conversions. The first conversion completes with the sequence **`A`**, `A`, `A`, **`B`**, **`C`**, `C`, and the second conversion completes with the following sequence of **`A`**, **`B`**, **`C`**.

<div class="alert alert-info"> Any action or view that happens between two steps in a funnel does not impact the step-by-step or overall conversion rate. As long as step A and C happen in the right order in a given session at least once, it counts as a single converted session.</div>
<div class="alert alert-info"> Any action or view that does not match a funnel step does not impact the step-by-step or overall conversion rate. If all funnel steps occur in the right order within the conversion window, Datadog counts the session as a single converted session.</div>

Datadog calculates the average time between steps by averaging the total duration between the first and last step of each conversion over the total number of steps.
