The thing to nail down with any CPV is what counts as a view. Platforms define it differently — a 2-second or 6-second watch, a completed (100%) view, or quartile milestones (25 / 50 / 75 / 100%). A completed-view CPV and a 2-second CPV are very different contracts for the same creative, so always confirm the standard before comparing CPV across networks.
