Introduction to Nerd Alert
The episode kicks off with Leonard Jasper and Rob Demars diving into the "Nerd Alert" segment, where they explore complex marketing research and distill it into actionable insights. Leonard sets the stage by introducing a study that scrutinizes the effectiveness of third-party consumer profiling and audience targeting in digital advertising.
Understanding Data Types: First-Party vs. Third-Party Data
Timestamp: [02:24]
Rob Demars humorously explains the difference between first-party and third-party data using a cookie analogy:
"First party data is when you have the information in house... Third party data would be like buying cookies from a guy in the back of a Toyota Corolla... you might get something unreliable."
— Rob Demars [03:02]
Leonard emphasizes the importance of distinguishing between data sources, clarifying that first-party data pertains to information directly collected from your own customers, while third-party data is acquired from external sources, often leading to inaccuracies.
The Study: Assessing Third-Party Data Accuracy
Timestamp: [02:43]
Leonard introduces the study titled "How Effective is Third Party Consumer Profiling and Audience Delivery?" by Nico Newman, Katherine Tucker, and Timothy Whitfield (2018). The research aims to determine the actual performance of third-party data in targeting specific demographics and interests.
Study One: Programmatic Campaign Simulation
Timestamp: [03:17]
- Method: Simulated a typical programmatic campaign targeting men aged 25 to 54 using six major Demand Side Platforms (DSPs) and 19 data brokers.
- Findings: On average, 59% of ad impressions correctly reached the intended demographic. While better than the random baseline of 26.5%, the accuracy varied significantly across different DSPs, ranging from 40% to 72%.
Leonard notes the modest improvement over random targeting but underscores the variability and potential inefficiency.
Study Two: Raw Accuracy of Data Segments
Timestamp: [04:33]
- Method: Assessed the accuracy of demographic labels (age and gender) from third-party brokers against verified self-reported data from consumer panels.
- Findings: The average accuracy for identifying men aged 25 to 54 plummeted to just 24.4%, worse than random gender guessing. Gender accuracy averaged 42%, and age accuracy ranged between 10% to 32%, highlighting significant inaccuracies.
Rob reacts with surprise:
"Wow."
— Rob Demars [05:27]
Study Three: Interest-Based Targeting
Timestamp: [05:28]
- Method: Shifted focus from demographics to interests such as sports, fitness, and travel.
- Findings: Interest-based targeting showed improved accuracy, climbing to the 70-80% range. While still imperfect, this method outperformed demographic targeting.
Cost-Benefit Analysis of Third-Party Targeting
Timestamp: [06:04]
Leonard discusses the economic aspect, revealing that third-party audience targeting often doesn't justify its cost unless applied to higher-priced media. For lower CPM (Cost Per Thousand Impressions) platforms like display advertising, the performance gains do not outweigh the additional costs.
A standout quote from the study:
"Third party audiences are often economically unattractive."
— Study Highlight
Leonard interprets this as third-party data frequently not offering sufficient value for its price, leading to mismatched impressions and wasted advertising spend.
Practical Implications for Marketers
Timestamp: [07:30]
Leonard advises brand managers and media planners to critically evaluate their use of third-party data. Key considerations include:
- Accuracy Verification: Ensuring that the targeted audience truly aligns with the intended demographic.
- Cost Justification: Weighing the additional costs against the performance benefits.
- Testing and Skepticism: Experimenting with and without third-party data to assess its real-world effectiveness for their specific brand.
Rob adds a relatable perspective:
"Buying a third party data set is like paying for a VIP concert ticket and ending up in the parking lot."
— Rob Demars [08:54]
He underscores the frustration of investing in data that fails to deliver the desired audience, likening it to a disappointing concert experience.
Counterarguments and Final Thoughts
Timestamp: [10:31]
Leonard acknowledges that while the study presents a compelling case against third-party data, some scenarios may still warrant its use, particularly when targeting high-cost media where the additional expense is offset by the media spend. He advocates for a balanced approach, suggesting that marketers remain open to testing third-party data sets but maintain a healthy skepticism regarding their effectiveness.
Rob concludes with a succinct takeaway:
"Not all third party data is created equal."
— Rob Demars [11:46]
Leonard echoes this sentiment, encouraging listeners to evaluate the quality of their data sources critically.
Closing Remarks
The episode wraps up with acknowledgments to the production team and invitations for listeners to connect on LinkedIn and leave reviews. Leonard and Rob sign off by reiterating the importance of building effective marketing strategies based on reliable data insights.
Key Takeaways
- Third-Party Data Accuracy: Significant inaccuracies exist in third-party demographic targeting, often performing worse than random targeting.
- Interest-Based Targeting: Offers better accuracy but still falls short of perfection.
- Economic Viability: Third-party data targeting is generally not cost-effective for lower-priced media but may justify costs in high-value advertising scenarios.
- Strategic Evaluation: Marketers should critically assess the value of third-party data, considering both accuracy and cost, and remain open to testing its effectiveness within their specific contexts.
