Traffic that is not a real person with real intent. Bots, scrapers, data center traffic, and developer testing scripts that nobody turned off. General IVT is mostly accidental. Sophisticated IVT is deliberate fraud. Both inflate your impression counts and dilute your results. The distinction matters because SIVT requires active detection, not just filtering. If your verification vendor is not calling out SIVT separately, ask why.
