Third-party measurement vendors provide independent verification and analytics for India CTV campaigns beyond what DSPs and publishers self-report. Using a third-party vendor is standard practice for campaigns above ₹25–50 lakh — it provides a neutral audit of delivery, fraud levels, and audience verification. Understanding which vendors operate in India CTV, what each measures, and where they have integration gaps is the starting point for building a measurement plan.
DoubleVerify (DV)
DoubleVerify is the most widely used third-party CTV measurement vendor in India among large advertisers and agency holding companies. DV's CTV measurement covers: invalid traffic (IVT) screening to detect bot traffic and device spoofing; viewability-equivalent metrics (VCR verification, ad placement verification); brand safety classification; and app verification to confirm the ad was delivered to a declared app, not a fraudulent one.
Integration: DV integrates via VAST pre-bid and post-bid wrappers attached to the DSP's ad tag. Works with DV360 and The Trade Desk in India. Does not have direct integration with JioHotstar's full inventory — only JioHotstar inventory accessed via programmatic SSPs is measurable by DV.
Integral Ad Science (IAS)
IAS provides similar CTV measurement to DV — brand safety, IVT, viewability classification — and is used by some India agencies as an alternative. IAS's India CTV publisher integration is slightly narrower than DV's as of 2026. IAS's Total Visibility product provides a combined view of digital delivery across CTV, mobile, and display, which is useful for cross-channel campaigns.
Nielsen ONE and Nielsen Digital Ad Ratings (DAR)
Nielsen's India CTV measurement capability is less mature than in the US. Nielsen DAR, which provides demographic audience verification for digital campaigns, has limited CTV publisher integration in India. Nielsen ONE, the cross-media measurement system, is in deployment in India but not yet widely used as a trading currency for CTV. Advertisers accustomed to Nielsen as a measurement currency in other markets must adapt to a different landscape in India.
AppsFlyer and Adjust (mobile measurement partners)
AppsFlyer and Adjust are mobile measurement platforms (MMPs) relevant to CTV when the campaign objective includes app installs or in-app conversions. These platforms handle cross-device attribution — connecting CTV ad exposure on a TV device to an app install on a mobile device — through household IP matching and device graph resolution. Both have India-specific operations and work with DV360 and TTD CTV campaigns. Limitation: JioHotstar direct inventory is not available for MMP-based view-through attribution.
BARC India (panel-based)
BARC provides the only panel-based audience measurement for OTT/CTV in India — the one source that counts actual viewers rather than device IDs. BARC OTT data is monthly, platform-level, and not campaign-specific. Used for planning and post-campaign context, not real-time optimisation.
