Data segmentation
Yandex Metrica collects and processes a large volume of information about site users. For certain business cases, sometimes you need to get a subset of data from this large dataset.
In addition to selecting user sessions for a specific action (such as viewing a specific page or click-throughs from a particular source), Yandex Metrica lets you select user parameters such as gender, age, and so on.
It may also be important to get statistics on users who performed a certain action in the past, and analyze the connection between past and present behavior.
The data that Yandex Metrica uses for making a report like this can be shown as follows: 
To build a report with just the data you are looking for, create a segment with the relevant conditions.
Segments can be created not only in the web interface but also using the Yandex Metrica API. Each of these ways allows creating up to 500 segments. This means that you can have a total of up to 1000 segments per tag.
When working with segments, keep in mind:
- Segments created in the web interface can be used in Yandex Direct and Yandex Audiences.
- Segments created via the API can only be used for retargeting in Yandex Direct. They are not shown in the Yandex Metrica web interface.
- In some cases, a segment created in one of the Yandex Metrica reports does not work in another report or is not available in Yandex Direct and Yandex Audience. For example, you can't use a segment created in a Yandex Direct, costs report in any other report, nor can you use it when selecting an audience in Yandex Direct.
Note
You can use the API to modify segments that were created in the web interface, but they will no longer be shown in the web interface after this.
