A carpet sales retailer is rolling out a new line of carpeting and would like to advertise their video ads within home furnishings inventory.Before they set up their campaign in Campaign Manager 360, what’s the first step they should take?

Before setting up a campaign in Campaign Manager 360, it's crucial to confirm publisher requirements, especially for specific campaign dimensions. This ensures that the video ads will be compatible with the inventory available from home furnishings publishers, preventing technical issues and wasted effort later. Without this step, the created assets might not fit the publisher's specifications, leading to delays and rework. Creating companion banners or adjusting file sizes are subsequent steps that depend on these initial publisher requirements. Sending video ad tags prematurely without confirmed specifications is inefficient and likely to result in errors.
