Approving an ad says it is ready to publish, so it is worth a proper look rather than a glance at the thumbnail.

• Compare it against what was submitted. The assembled ad sits side by side with the original creative, which is the fastest way to catch a template or crop that changed something you cared about.

• Read the comments before you decide. Anything left on the ad is context you may not have.

• Approve when it is right. The ad moves to Approved and becomes available to publish. Nothing goes live at this point.

• Changed your mind? An approval can be undone from its group afterwards.
