Yandex has introduced a feature within Metrica allowing webmasters to compare costs (via manual upload via a CSV or API connector) to performance, to establish an ROI across multiple traffic and conversion channels.
Given Metrica’s ability to also record search queries (in a more comprehensive way than Google Analytics), you can also attribute campaigns (say you run a specific campaign over a specific topic) to ROI on actual queries.
Yandex’s Commercial Director Dmitry Kachmar went on record to say:
In Metrica, we are gradually creating an accessible system of end-to-end analytics, which will allow us to receive comprehensive information about the effectiveness of our promotion. A report on ROI and advertising costs is a big step in that direction. It will help to quickly identify the promotion channels that pay off best and optimally distribute the advertising budget. In the future, we will add other capabilities for end-to-end analytics.
