Ampd's campaign duplication feature allows you to double down on winning keywords and test different keyword groups.
Hover over the name of your campaign and click the "details" button. Then click "copy" which will copy the campaign and bring you to the page right before launching. From there you can edit the ad copy or keywords before launching.
We recommend using this "copy" feature to A/B test landing pages, target different keyword groups and run keyword isolation strategies, as seen below.
