How adjustments are applied
If a campaign has a manual bid management strategy set up, adjustments are applied to the bids set by the advertiser.
If a campaign has an automatic strategy set up, Yandex.Direct applies the adjustments when managing bids. If strategy parameters specify the maximum bid, adjustments are also applied to this maximum. In other words, the system won't set a bid that is higher than the adjusted maximum bid. If the average CPC or CPA is specified, adjustments are not applied to it.
If an ad group has at least one adjustment set (and this type of adjustment is not disabled), the same type of adjustments set for the campaign are not applied when displaying ads from this group.
If a user is selected by multiple retargeting lists that have adjustments set for them, the largest coefficient is applied.
If adjustments are set for a higher-level region and a lower-level (nested) region, ad displays in the lower-level region use the coefficient for the lower-level region.
Multiple types of adjustments can be applied to a bid simultaneously. In this case, the coefficients are multiplied.
An adjusted bid can't be less than the minimum or more than the maximum value for the advertiser's currency. See Minimum and maximum CPC.
