Audience

Segments based on your own data

First prepare a file containing the data you wish to use. This file can contain email addresses, mobile phone numbers, or mobile device IDs. The file must have at least 1000 data strings and must meet the file requirements. If you have security concerns, the data in your file can be hashed (md5). In this case, every data string needs to be hashed separately.

Example of a TXT file containing email addresses without hashing:
example1@yandex.ru
example2@mail.ru
example3@yandex.ru

Yandex.Audience can use email addresses and mobile phone numbers to find data about users in Russia and the CIS, while mobile device IDs can provide information about users all over the world.

Click Create segment. Under Based on my data, choose the type of data, such as Phone numbers. Enter a name for the segment and select the file you've prepared. If the data in your file is hashed, check the box marked Hashed data. Check the box to confirm that you agree to the Terms of Service and click Create segment.

The segment you create will be assigned the “Processing” status. Processing can take up to thirty minutes.

In this time, Yandex.Audience will find matches between the data in your file and all of Yandex's accumulated data. For example, Yandex.Audience can identify your client as a user of one of Yandex's services or a visitor to a Yandex Advertising Network site based on their email address.

Cookies found in these users' mobile apps and browsers will be added to the segment. Coverage refers to the overall number of cookies in a segment. Since an individual can use several different devices and browsers (for example, at home and at work), the number of newly-found contacts and the new segment coverage figure might not match.

If more than 1000 such contacts are found, the segment status will change to “Finished”. Now you can use this segment to set up your ad campaign.
