The name of the Search Ads 360 bid strategy that is managing bids for a keyword, ad group, or campaign.
In Search Ads 360, bid strategies can be applied to a campaign and then inherited by all ad groups and keywords in the campaign. Any individual ad group or keyword can override the campaign's setting by specifying its own bid strategy. If you include both "paid search keyword" and "paid search campaign" as dimensions in a report, the "paid search bid strategy dimension" displays the bid strategy that's in effect for the keyword. Likewise, if you only include the "paid search campaign" dimension, the "paid search bid strategy" dimension will be empty unless a bid strategy has been applied to the campaign.
