See a history of DS bid strategy changes

DoubleClick Search (DS) provides a couple of ways to view the history of changes in a DS bid strategy:

  • If you want to focus on just seeing the changes to bids, you can download the bidding history for one or more biddable items. The bidding history shows each change made to a bid, when the change was made, and whether the bid was automatically changed by a bid strategy or manually changed by a DS user.
  • If you want to see a detailed history of bid strategy activity, including changes to bids and bid adjustments and whether the bid strategy is recommending bids, rationale behind any changes that the bid strategy makes, view the full change history in the user interface, in the change history report.
