An Overview of Traditional TV Mesurement Methods
TV advertising measurement for linear (broadcast and cable) started with traditional attribution methods—panel ratings and GRPs, vanity URLs and coupon codes, matched-market tests, call tracking, and survey recall. Those tools helped estimate response, but they blur correlation and causation, miss delayed effects, and offer little week-to-week optimization. In this guide, we explain the classic approaches (A/B market tests, MMM/GRP models, last-touch proxies), where they break down, and how modern time-series spike analysis and syncopated-response modeling provide clearer, incremental lift for linear TV campaigns.
1-800 Numbers
Traditional TV Attribution Method:
Brands once assigned unique toll-free numbers to various commercials. The idea was simple: if a viewer called after seeing a particular TV spot, that response could be attributed to that ad. While intuitive, this method posed significant challenges:
- Missed Branding Opportunities: Sticking to multiple vanity numbers limited the ability to build brand equity around a memorable central phone line.
- Costly Setup: Individual production dubs, numerous phone lines, and a dedicated call center team quickly drove up expenses.
- Limited Granularity: With only a handful of unique numbers at your disposal, tracking the incremental lift from hundreds or thousands of ads was nearly impossible.
Why It Falls Short Today:
In the modern era of tv attribution and spike analysis, brands demand more precise data. Relying on phone calls alone captures a fraction of actual engagement, ignoring online searches, direct web visits, and other digital conversions that often follow a TV spot.
Rating Systems
Traditional TV Attribution Method:
Traditional rating systems estimate viewership by installing specialized equipment in a sample of households. The resulting data is extrapolated to represent the entire country’s TV audience. However, this approach struggles to provide the actionable detail marketers now seek:
- Sampling Issues: A tiny subset of households determines national viewership metrics.Impressions Over
- Actions: These systems measure who might have watched a show, not who took a meaningful next step—like visiting a website or making a purchase
- Slow Updates: Monthly or quarterly refresh cycles fail to guide quick optimizations, leaving advertisers with outdated insights that can’t inform nimble strategy adjustments.
Why It Falls Short Today:
Modern tv analytics and incremental lift analysis give brands a direct line of sight into how viewers respond in near real-time. By focusing on tangible outcomes rather than broad estimates, advertisers can make data-driven decisions that improve campaign ROI on the fly.
Discount Codes, Vanity Landing Pages and Website Domains
Traditional TV Attribution Method:
In an attempt to go beyond rough estimates, some advertisers relied on unique discount codes or custom URLs mentioned in their TV spots. While better than 1-800 numbers, this tactic still has glaring limitations:
- Low Compliance: Many viewers forget the exact code or never bother using it, preferring to search the brand name directly online.
- Limited Scope: Custom domains or vanity URLs only capture a sliver of the response. Studies show these methods might record as little as 30% of total interest.
- Effort & Expense: Producing multiple versions of a commercial, each with its own code or URL, increases complexity and costs without guaranteeing rich, granular data.
Why It Falls Short Today:
Instead of relying on easily forgotten codes, modern attribution leverages lift analysis and spike analysis to track real user behavior—such as organic searches or direct site visits that occur after an ad airs. This approach gives a clearer, more holistic picture of campaign performance.
Self Reported Attribution
Traditional TV Attribution Method:
Sometimes brands tried to pinpoint origins by asking users directly: “How did you hear about us?” While seemingly straightforward, this approach is fraught with problems:
- Biased Results: The order of listed options can sway responses.
- User Distraction: Visitors come to your site to accomplish something—filling out a form about how they discovered you may not rank high on their priority list.
- Overlapping Channels: Users often encounter multiple touchpoints. Expecting them to neatly assign credit to one channel leads to guesswork and randomness rather than reliable data.
Why It Falls Short Today:
In contrast, cutting-edge tv attribution methods use sophisticated analytics models to calculate incremental lift without burdening the user. By analyzing traffic patterns before, during, and after ad airings, modern solutions eliminate guesswork and deliver objective, data-backed insights.
