Pricing, viewability, and clicks

CPM

CPM is the Campaign bid in minor currency units per 1,000 verified Viewable Impressions. An impression qualifies when at least 5,000 basis points of the creative remain visible for at least 1,000 ms. MiniCenter accumulates integer charges deterministically; sub-unit fractions are not rounded into duplicate spend.

Submit the signed decision token to record a Viewable Impression. Replaying the same interaction is deduplicated.

CPC

CPC charges the Campaign bid on the first valid Click for a signed Ad Decision. Later requests with the same token still redirect to the reviewed destination but do not charge again.

Follow the signed URL documented by record a Click. The redirect response includes Cache-Control: no-store and a no-referrer policy. Never cache or rewrite the token.
