You can edit bids directly from the ad group or keyword table.
If you're not already on the Campaigns page, please click All campaigns in the left nav.
Under one of the bids columns (such as Search max CPC, Broad max CPC, or Exact bid) in the table, click the bid and update it in the text box that appears. You can change it to a specific amount, or you can increase or decrease the current bid by a certain percentage or amount.
Click Save.
