What is invalid traffic (IVT) in India CTV and how is it detected?

Invalid traffic (IVT) in CTV is any ad impression that is not delivered to a real human viewer watching a real television screen. IVT in CTV takes several forms: (1) App spoofing — a fraudulent seller misrepresents a low-quality mobile or desktop impression as a premium CTV app impression by faking the app bundle in the bid request. (2) Device spoofing — mobile devices or servers emulate CTV device signatures (device.devicetype = 3) to attract higher CTV CPMs. (3) Bot traffic — automated systems generate fake CTV ad requests without a real viewer. (4) Ad stacking — multiple ads served simultaneously in the same screen position, with only the top ad visible — less common in CTV than in display but possible in poorly governed app environments. Sophisticated IVT (SIVT) is the harder-to-detect category that attempts to mimic legitimate viewer behaviour.

India CTV IVT rates are lower than open web display but not negligible. Third-party verification vendor reports (IAS, DoubleVerify) for India CTV programmatic inventory show IVT rates of 3–8% across open auction inventory — compared to 1–3% for premium direct-bought CTV and 15–25% for open web display. App spoofing is the primary IVT vector in India CTV — driven by the premium CPMs that CTV commands relative to mobile. The risk is higher in open auction (where any seller can submit CTV-flagged bids) than in PMP or direct deals with verified publishers. India-specific risk: the large number of small, poorly governed regional streaming apps creates more IVT surface area than mature Western CTV markets.

Four practical steps: (1) Use app-ads.txt verification — only buy from SSPs listed as authorised sellers in the publisher’s app-ads.txt file. This blocks most app spoofing. Activate app-ads.txt filtering in your DSP settings. (2) Use an inclusion list — restrict programmatic buying to a curated list of known, verified India CTV apps (JioHotstar, Sony LIV, Zee5, MX Player, Samsung TV Plus) rather than buying all CTV inventory in a DSP. Open domain or app lists are the primary IVT entry point. (3) Activate third-party IVT filtering — IAS or DoubleVerify pre-bid segments block known IVT sources before the bid is placed. (4) Monitor delivery signals — VCR above 95% on supposedly skippable formats, impressions delivered uniformly 24 hours a day, or unusually high delivery from specific unknown apps are IVT indicators requiring investigation.
