What is a GRP in CTV and can you plan India CTV campaigns using GRPs?

A Gross Rating Point (GRP) represents 1% of the target audience exposed to an ad once. A campaign delivering 100 GRPs among 25–54 adults means the ad reached, on average, the equivalent of 100% of that demographic (which could mean 50% reached twice, or 100% reached once, etc.). GRPs are the standard planning and buying currency for linear TV in India — BARC India provides TVRs (Television Rating Points, the single-broadcast equivalent of GRPs) that agencies aggregate into GRP totals to assess campaign weight. GRPs allow apples-to-apples comparison across channels because they normalise for audience size — a 1 GRP on a programme with 10 million viewers delivers the same planning unit as a 1 GRP on a programme with 50 million viewers (proportionally).

CTV GRP planning is possible but requires bridging CTV impression data to a common audience denominator. The process: (1) Establish a target audience universe (e.g., SEC A/B adults 25–54 in urban India, approximately 80 million people). (2) Use CTV platform reach data or DSP reach planning tools (DV360 Reach Planner, The Trade Desk Koa) to estimate unique reach as a percentage of that universe. (3) Multiply reach percentage by average frequency to get GRP equivalent. In practice, CTV GRP planning in India is limited by incomplete audience data — publishers do not all report audience in BARC-equivalent demographic terms. Nielsen’s Digital Ad Ratings is the closest bridge product, measuring CTV campaign reach in demographic terms that can be expressed as GRP-equivalents.

Plan in impressions with a reach-and-frequency framework, not in GRPs, for India CTV. GRPs are useful when comparing CTV to linear TV within a unified TV budget, but they introduce false precision — the audience estimates required to convert CTV impressions to GRPs carry wide confidence intervals. For a pure CTV campaign, the practical planning currency is: total impressions (how many ad plays), unique household reach (estimated unique devices/households), and average frequency (how many times the average reached household saw the ad). These three numbers, combined with a CPM, give a cleaner campaign design than a GRP target. Save GRP framing for cross-channel presentations to brand teams still anchored in linear TV language.
