Vast Blast eligibility requirements

Vast Blast uses eligible content from your channel to generate visual distribution units for approved publisher placements. You do not manually design the ad unit.

Channel requirements

To activate Vast Blast, your channel needs:

• at least four public, populated chapters;
• at least four posts in each chapter used to supply a chapter-level Blast experience;
• eligible visual media.

Empty chapters, ineligible text-only content, or a channel that falls below the requirements do not power Blast.

What happens when eligibility changes?

If your channel falls below the requirements, the affected Blast access is disabled until the requirements are restored. VAST shows unlock or requalification guidance in the creator flow.

What content can Blast use?

Blast can draw from your channel, chapters, selected featured posts, and eligible media. In the Blast preview, photos from your Main Square appear in the middle. Your chapters appear as selectable panels on the left and right sides. When you select a chapter, the posts from that chapter appear in the middle area.
