There are 2 methods for adding additional keywords to a campaign which has already been submitted.
1) Manually add the keywords in your AdWords/BingAds/YSM account, then go to your campaign in adCore™'s Dashboard under the Campaigns tab. Click on the 'Synchronization Settings' icon (), and set the 'Sync keywords' section to 'Add Only' by clicking on the drop-down menu. Then click 'Save'.
2) You can also choose to create additional keywords entirely through adCore™. To do this, simply add the keywords in the appropriate section of the campaign builder.
