Your TV Spend Is Smarter Than You Think—If You Know Where the Calls Are Coming From

Television advertising remains one of the most potent channels for brand awareness and customer engagement. Yet, marketers frequently underestimate its value due to difficulty in directly linking TV spend to measurable outcomes. According to the 2023 Deloitte CMO Survey, approximately 42% of marketers have cut back on TV budgets precisely because of the challenge in demonstrating clear attribution. Paradoxically, Nielsen’s Report from 2024 reaffirms that TV consistently ranks among the top channels for generating brand lift and substantial call volumes.

The core issue lies in attribution—without clear insights into which ads trigger consumer calls and actions, marketers find themselves navigating without a compass. This gap, often perceived as an ROI blind spot, results in underinvestment in television advertising, leaving significant opportunities for customer engagement and revenue growth unrealized. In this article, you’ll learn effective strategies to accurately track and attribute TV-driven calls, enabling smarter investment decisions and maximizing your marketing ROI.

Why Attribution Is Tougher for TV Than Digital

Attribution in digital marketing has become relatively straightforward thanks to tracking technologies such as cookies, pixel tracking, and advanced analytics. However, TV advertising attribution remains significantly more complex due to several inherent challenges. Unlike digital channels, linear and over-the-top (OTT) television ads don’t always generate immediate actions; their impact often surfaces after delays ranging from hours to days, complicating direct attribution.

Moreover, traditional attribution models typically rely on direct and immediate interactions. TV advertising, however, works differently by building cumulative brand awareness and influencing purchasing decisions gradually. According to Salesforce’s 2023 report, only 17% of marketers currently have a reliable method for tracking offline conversions, highlighting this crucial gap. ThinkTV Australia’s 2024 study further emphasizes this point by noting TV’s brand influence frequently peaks days after ad exposure, complicating straightforward attribution models.

How to Know Where the Calls Are Coming From

Effectively tracking calls driven by TV advertising involves leveraging a combination of specific methodologies designed to bridge the attribution gap. Here are three primary strategies to consider:

  1. Dedicated Call Tracking Numbers: Assign unique phone numbers to specific ads, time slots, or geographical regions. Done correctly, this method should be the gold standard of data that directly ties to an ad.
  2. Time-Based Attribution Models: Correlate call spikes with TV ad airings to identify patterns. Internal surveys indicate that only 16% of viewers call immediately after viewing an ad, whereas 60% respond after a delay, highlighting the importance of longer attribution windows.
  3. Survey-Based Attribution: Utilize direct customer surveys to ask explicitly how callers heard about your product or service. This qualitative data supplements quantitative tracking, providing a fuller attribution picture.

Putting It All Together: A Multi-Method Approach

No single method of attribution provides a complete picture on its own—especially when it comes to TV advertising. To maximize confidence in your ROI calculations and media optimization strategies, marketers must adopt a triangulated approach that blends quantitative and qualitative signals.

A common framework combines call tracking data, time-based attribution windows, and post-call survey inputs with broader modeling techniques like marketing mix modeling (MMM). For example, by aligning call surges with TV airings and validating those links with survey responses, you can improve the accuracy of your spend attribution across dayparts, regions, and creative types.

When these foundational methods are paired with advanced modeling techniques such as MMM and regression analysis, marketers gain a scientific lens for interpreting media performance. MMM uses historical data to isolate the incremental impact of TV among other channels, while regression models allow for statistically significant comparisons across variables like channel, timing, geography, and audience segments. Together, these tools help separate correlation from causation and give marketers a credible basis for making high-stakes budget decisions.

Case Study: Turning TV Call Data into Smarter Spend

Not long ago, a media buyer found himself in the thick of uncertainty. He was managing ad placements for a brand that manufactured American-made garage equipment—airing commercials across networks like FOX, ABC, and ESPN. These ads ran at noon, mid-afternoon, evening—a dizzying mix of variables. Despite steady increases in sales, he couldn’t confidently say whether TV was truly driving the results or if the digital channels—whose dashboards always claimed success—were doing all the heavy lifting.

The pressure was mounting. The brand owner wanted answers. Budgets were on the line. And without attribution, the media buyer felt like he was flying blind.

Determined to get clarity, he leaned into the strategies outlined in this article. He set up dedicated call tracking numbers for each time slot. He built a time-based attribution model that connected call surges to specific TV airings. And he implemented post-call surveys to hear directly from customers about what influenced them to pick up the phone.  With that foundation, he layered in digital tracking and began modeling the overlap. By combining TV attribution with digital signals and regression analysis, he could finally see the full picture—and prove that TV ads weren’t just contributing, they were crucial.

That proof gave the brand owner the confidence to act. Instead of scaling back, he doubled down on the most effective dayparts and creative. Within months, profits surged. The company expanded into a larger manufacturing facility and hired new employees to meet growing demand.

Conclusion: Don’t Underspend on a Channel That’s Working

Television advertising may not offer the immediate feedback loops of digital channels, but that doesn’t mean it’s not working—it just requires the right lens to measure. As we’ve explored in this article, tracking call data, using time-based attribution, and layering in customer surveys are foundational steps toward bridging the offline attribution gap.  When these techniques are reinforced with marketing mix modeling and regression analysis, you unlock a scientific, high-confidence way to understand exactly how your TV spend drives business outcomes. You no longer need to rely on gut instinct or hope that digital dashboards tell the full story.

The lesson is clear: when armed with the right data and methodology, you can uncover the real value of your TV investments, justify greater spend with confidence, and transform uncertainty into growth. Don’t let lack of attribution data hold you back from scaling a channel that may be quietly doing the heavy lifting.

FAQ: TV Attribution and Call Tracking

  1. How can I track calls back to specific TV ads? Use dedicated call tracking numbers tied to specific air times or regions. Pair this with time-based attribution and customer surveys to increase accuracy.
  2. What if callers don’t respond immediately after seeing an ad? That’s common—only 16% call right away. Most call later, which is why time-based models and surveys are crucial.
  3. How do surveys support TV attribution? Surveys ask customers how they heard about you, which helps validate and supplement data from call logs and air time tracking.
  4. How does marketing mix modeling (MMM) help? MMM uses historical data to measure the contribution of each channel, including TV, across time. It’s great for budget planning and optimization.
  5. What if my results conflict between methods? Use triangulation—combine tracking, surveys, and modeling to form a high-confidence, consensus-driven attribution story.
  6. Is this approach only for large advertisers? No. Even small-to-mid-sized advertisers can use these methods. There are scalable tools available for call tracking and basic regression.

7. How soon can I expect ROI from TV attribution improvements? Many brands begin seeing clearer results and smarter budget allocations within one to two quarters of implementing a structured attribution system.
