Video Ads and Commercial Research & Evidence-Based Practice 2 — Questions and Answers
Question 1: A brand wants to test whether a 15-second ad outperforms a 30-second ad. Which research design best isolates ad length as the variable?
- A/B split test with identical creative except duration (Correct answer)
- Focus group comparing both versions simultaneously
- Day-part rotation with different audiences
- Sequential exposure testing on the same panel
Correct answer: A/B split test with identical creative except duration
An A/B split test controls all creative elements except length, isolating duration as the single independent variable.
Question 2: Which metric from a brand lift study directly measures whether viewers recall seeing your ad?
- Ad recall lift (Correct answer)
- Purchase intent lift
- Brand favorability lift
- Awareness lift
Correct answer: Ad recall lift
Ad recall lift specifically measures the percentage point increase in viewers who remember seeing the advertisement.
Question 3: A video ad campaign shows high view-through rate but low conversion. What research step should come next?
- Conduct a path-to-purchase analysis to identify drop-off points (Correct answer)
- Increase ad frequency to build more familiarity
- Switch to a shorter ad format immediately
- Pause the campaign and restart with a new creative
Correct answer: Conduct a path-to-purchase analysis to identify drop-off points
A path-to-purchase analysis reveals where in the funnel viewers are disengaging after watching the ad.
Question 4: What does 'incremental reach' measure in video advertising research?
- The unique audience exposed via video that was not reached by other channels (Correct answer)
- Total impressions delivered across all placements
- The percentage of the target audience who watched 100% of the ad
- Overlap between linear TV and digital video audiences
Correct answer: The unique audience exposed via video that was not reached by other channels
Incremental reach identifies new, unduplicated viewers that video ads add beyond what other media already reached.
Question 5: Which statistical concept is critical when interpreting brand lift study results to ensure findings are not due to chance?
- Statistical significance (Correct answer)
- Frequency capping
- Viewability threshold
- Gross rating point
Correct answer: Statistical significance
Statistical significance confirms that observed lift differences between exposed and control groups are unlikely to be random.
Question 6: A researcher finds that ad effectiveness declines sharply after 4 exposures. This finding relates to which concept?
- Wear-out (Correct answer)
- Recency planning
- Share of voice
- Contextual targeting
Correct answer: Wear-out
Ad wear-out describes the diminishing returns and eventual negative effects of excessive repetition on audience response.
Question 7: In video ad research, what is the purpose of a 'control group' in a brand lift study?
- To represent unexposed users as a baseline for measuring ad-driven change (Correct answer)
- To test multiple ad versions simultaneously
- To identify the demographic most receptive to the ad
- To measure organic search volume before the campaign launches
Correct answer: To represent unexposed users as a baseline for measuring ad-driven change
The control group provides a baseline of non-exposed respondents so researchers can attribute metric changes specifically to the ad.
