Hallmark and iSpot measure CTV advertising through to purchase – what the data does not prove

Hallmark is combining classic TV, streaming and FAST reach with website visits and purchases through iSpot. The US deal shows tomorrow's measurement standard – and the gap between attribution and incrementality.

Hallmark Media is having its advertising campaigns across classic television, streaming and free ad-supported TV services measured by iSpot. The US partnership, announced on 1 October 2026, is meant to bring together the audiences reached and link ad exposures with website visits, store visits and purchases. For advertisers, this is a step away from isolated TV reach figures – not automatic proof of additional sales.

Three measurement tasks instead of one new miracle metric

According to the joint announcement from Hallmark and iSpot, the technology is meant to address three problems:

1. Additional reach: Which viewers are reached via streaming that a linear TV campaign did not reach? 2. Deduplicated contacts: How many people or households were reached across the different channels without counting repeat contacts as a new audience? 3. Attributed outcomes: Which visits, installations or purchases can be observed following measurable ad exposures?

Hallmark is using iSpot's Unified Measurement and Outcomes at Scale for this. The announcement does not disclose how large the actual added value in reach or revenue turns out to be. The agreement is therefore initially a new measurement option, not a documented campaign success.

What European CTV standards additionally require

Precisely because streaming and linear television are evaluated together, methodology and data basis must be disclosed. The IAB Europe CTV Measurement Framework of 1 October calls for comparable definitions and transparent limits, for example in modelled reach, co-viewing and the actual device status.

For German media teams, these questions are therefore more important than an impressive reach figure: Are households or individuals being counted? How are duplicate contacts recognised? How large are the modelling shares? Can the result be reconciled against the advertiser's own data?

That the US partnership coincides with a broader reshaping of TV measurement is shown by our overview of iSpot, Comscore and VideoAmp in the US JIC system. A JIC certification does not, however, replace a campaign's own quality check.

Attribution is not the same as additional revenue

A purchase after an ad contact may have been influenced by the advertisement – or would have happened anyway. Linking exposure and purchase answers the question of which outcomes can be attributed to a contact. Whether the advertising triggered additional purchases requires a suitable comparison or control group.

That is why advertisers should distinguish two measurement layers: cross-channel contact and conversion data for operational optimisation, and, where possible, controlled incrementality measurement for budget decisions. Similar questions arise with Netflix's new conversion interfaces and with Lowe's retail media measurement with Ipsos.

Why Hallmark is a suitable test case

The partnership started shortly before the Christmas season. Hallmark's Countdown to Christmas has been running since 16 October and combines linear premieres with streaming analysis the following day via Hallmark+. Recurring programme content and loyal viewer contact make it economically attractive for the broadcaster to sell reach across channels rather than in isolation. A particular purchase effect among this audience is not proven.

The need for action among advertisers is real: in an iSpot survey from May 2026, more than 45 percent of surveyed marketers named business results as the most important criterion in media buying; 47 percent described results measurement as a significant challenge. This is a vendor survey, not representative German figures.

Classification for Germany: The Hallmark–iSpot solution is a US partnership. What matters most is the measurement logic: anyone steering CTV, social video and classic television in one budget must evaluate reach, attributable conversions and actual lift separately.
