View bidding history for biddable items in a bid strategy

DS maintains a history of changes to bid settings for each biddable item that you can download to a file. The downloaded history file contains information about when bids were changed along with additional data to help:

  • Investigate the cause of performance changes.
  • Understand who made the bid change, when, and by how much. The bid history will tell you whether the bid was automatically changed by a bid strategy or manually changed by a DS user.
  • Give you the power to improve bid strategy performance. For example, if the downloaded history file shows that bid changes were constrained by bid strategy's maximum bid setting, you may want to increase the maximum bid setting bid so the bid optimization system can more freely optimize bids.

Follow these steps to download bid history for one or more biddable items:

  1. In the DoubleClick Search UI, select the Keywords tab or Product groups tab on any of the following pages:

    For example, to see the bid history of the keywords in a bid strategy, navigate to a bid strategy and select the Keywords tab.

  2. In the reporting table, select the check box next to the items whose bid history you want to see.
    You can select up to 30 items.

  3. The bid history file will include changes during the date range specified near the top right of the page.
    Click the date range to change it. If you select a date range greater than 90 days, the file will only include the history for the last 90 days.

  4. Click Download in the toolbar above the reporting table.
    The download panel appears.

  5. On the lefthand side of the download panel, click Bid history report.
    The settings for the bid history appear.

  6. Select the file format and click Download.
    If no bid changes occurred to a biddable item during the time span, the file will contain one row for the item, with the name followed by (no changes).
