To make sure the pottery company’s creatives serve to a major arts and crafts community site in Campaign Manager 360, you’ll need to download and send placement tags to the specific site.

• You’ll need to select the ad sizes for their campaign on the arts and crafts site.
• You’ll need to upload all of their arts-and-crafts-specific creatives into their account.
• You’ll need to select a range of placements on the arts and crafts site.
• You’ll need to download and send placement tags to the specific site.

The correct answer is: You’ll need to download and send placement tags to the specific site

Explanation: To ensure the pottery company’s creatives are displayed on the arts and crafts community site via Campaign Manager 360, placement tags are necessary. These tags are specific code snippets generated within CM360 for each designated ad space on that website. You, as the campaign manager, must download these tags from Campaign Manager 360 and provide them to the arts and crafts community site’s web team. They will then implement these tags on their webpages. This integration allows Campaign Manager 360 to recognize the ad slots and serve the pottery company’s creatives accordingly when users visit the site.
