The geotargeting tree will automatically be updated in Yandex.Direct and will not affect the reach of campaigns with Zabaykalsky Krai, the Republic of Buryatia, or the Far East enabled in their geotargeting settings. If you had selected the entire Siberian Federal District before the update, then all of the Siberian Federal District except Zabaykalsky Krai and the Republic of Buryatia will remain selected. The opposite is also true: if you had previously ticked the entire Far Eastern District, Zabaykalsky Krai and the Republic of Buryatia will remain unticked.
If you have bid adjustments set by display region, we recommend you check to see whether you need to make changes to your bid adjustments — make sure that you will maintain sufficient reach and not lose your target audience after these changes. You can read more about display region settings in the corresponding Help section.
This update to the geotargeting tree will lead to changes in the region directory in the Direct API returned by the Dictionaries.get and GetRegions methods. If your app does not support automatic updates to the geotargeting tree, you must make these changes manually as soon as the new data have become public (we will inform you once this happens).
