Why can't I see my campaigns in the Campaign Selector?
In order to see your campaigns in the Campaign Selector, you must first create the campaign in the relevant search engine advertising account, and follow one of the steps below:
Import the campaign through the Link Dashboard, by clicking on the 'Bulk Add Campaigns' button.
Select the 'Import from' radio button within the Campaign Selector (in the Submission Dashboard), and select the account under which your target campaign sits. You can then select your desired campaign from the list, and click Save.
