You sure can. You can login to your account and change your ad(s) at any time. Just go to Advertisers > My Ads and click on the pencil icon that appears when you hover over the name of the website for the ad you want to edit. After your new creative is submitted, the publisher will have 24 hours to approve it.
In addition to changing a current creative, you can also test multiple creatives in the same spot by using our A/B testing feature.
To use A/B testing, just go to Advertisers > My Ads and click on the name of the website for the ad you want to edit. On that page you will scroll down and click on the Add Alternate button to add one or more creatives to rotate in that space. Each creative can have its own URL and Alt text.
