# Segments Library - Metrics

Each segment displays the traffic percentage as well as the transaction rate. **This provides information on the segment usage in relation to the campaign as a whole**.

{% hint style="info" %}
Data is processed whenever you visit the Segment Library.

The calculation is based on the last 30 days for the eligible segment criteria.

Please note that if you combine an eligible criterion with an ineligible criterion, calculation won’t be processed.
{% endhint %}

This metrics calculation is based on the last 30 days.

### Traffic percentage <a href="#h_01hndbw7t2kra48jgpa8g18qgc" id="h_01hndbw7t2kra48jgpa8g18qgc"></a>

The percentage of total traffic is the **traffic percentage which your segment represents compared to the total visitor traffic on your website within the last month**. In other words, the number of visitors from the segment divided by the total number of visitors within the last month.

### Transaction rate <a href="#h_01hndbw7t26mpn0cg4ar20x4xj" id="h_01hndbw7t26mpn0cg4ar20x4xj"></a>

If the transaction tag has been implemented on the website, this coincides with the segment’s transaction rate. In other words, the **percentage of visitors who made a purchase out of all the visitors belonging to this segment**. For more on this, refer to [All about tags](broken://pages/kqhGHAgV5lYeW4ItvmBu).\
If several transaction tags have been placed, this coincides with the overall transaction rate.

### Eligibility <a href="#h_01hndbw7t26mpn0cg4ar20x4xj" id="h_01hndbw7t26mpn0cg4ar20x4xj"></a>
