How Yandex.Metrica detects the traffic source

Sources of traffic to a site are determined from the referrer (the HTTP Referer header) and tags. If you need to replace the referrer with your own, use the utm_referrer parameter.

Yandex.Metrica uses a tag to detect the traffic source if there is a tag in the data for the first pageview of the user's session. If there isn't a tag in the first pageview, the traffic source is detected from the referrer.

For example, a user clicked through to the site from a browser bookmark (the first pageview). Then the user left the site, but came back within 30 minutes by clicking a link with a tag in an email (the second pageview during the session). This session would be considered direct traffic to the site.
