Addressability in CTV means the ability to serve different ads to different households watching the same content. Unlike linear TV — where every viewer of a broadcast channel sees the same ad — CTV delivers ads to individual devices, enabling targeting by audience, geography, and household characteristics. Addressability is one of CTV's core advantages over broadcast, but its practical scope in India is narrower than in more mature markets.
What makes CTV addressable
Addressability depends on three components: a device identifier (so the system knows who to target), a data signal (so the system knows how to target), and an ad server that can match the two. On CTV, the device identifier is typically a GAID (Android TV), TIFA (Samsung), or AFAI (Amazon Fire OS). The data signal may be an audience segment from a DSP, a publisher's subscriber profile, or an advertiser's first-party customer list.
When a viewer watches JioHotstar on an Android TV and an ad break begins, the ad server knows the GAID of that device. If the advertiser has targeted GAID-linked audience segments — say, users identified as high-income, 25–44, Mumbai — the system serves that ad specifically to that device. The viewer next door watching the same show may see a completely different ad.
Types of addressable CTV targeting in India
Demographic targeting: Age, gender, income, SEC class. Derived from DSP modelled audiences or publisher subscriber data. Available on DV360, The Trade Desk, and JioHotstar direct.
Geographic targeting: City, state, pincode. One of the most reliable addressability signals in India — IP-to-geography mapping is reasonably accurate at city level. Available across all programmatic CTV channels.
Behavioural targeting: Viewers who have browsed specific content categories or shown purchase intent signals. Available via DSP audiences; quality varies by data source.
First-party audience targeting: Serving ads to an advertiser's own customers or suppressing existing customers from acquisition campaigns. Requires CRM-to-device ID matching. Match rates 15–35% in India.
Contextual targeting: Targeting by content category rather than viewer identity. Technically not addressable (same ad to all viewers of that content), but available without device ID data.
India-specific constraints on addressability
Device ID coverage: Approximately 30–40% of India CTV impressions lack a resolvable device ID — opted-out devices, older smart TVs, or publishers not passing the ID in the bid stream. These impressions are served contextually, not by device-level audience.
Audience data quality: Indian programmatic audience segments are thinner than US equivalents. Income modelling and lifestyle classification are less accurate across India's varied consumer landscape.
JioHotstar's walled garden: JioHotstar's addressability operates on its own subscriber data. Advertisers cannot bring DSP audiences directly into JioHotstar's full inventory.
Co-viewing: Even with perfect device-level addressability, the CTV ad reaches every person in the room. Addressability at the device level does not equal addressability at the individual viewer level.
Addressability vs reach: the India trade-off
Tighter audience targeting narrows reach. An advertiser targeting SEC A, 25–44, Tier 1 cities on JioHotstar may narrow to 15–20 million eligible devices. This is significant reach by global standards, but smaller than an untargeted buy. The trade-off between precision and reach is steeper in India than in the US because India's addressable device graph is smaller and less complete.
