Study goals
This study investigates the impact of different digital marketing strategies, applied across digital media channels, on sales conversion, brand recall, and favorability in the Hair Care segment, using A/B testing and Brand Lift studies.
Relevance / originality
We offer unprecedented evidence in Brazil on the integrated comparison between full-funnel and direct-conversion strategies, simultaneously analyzing performance and brand perception metrics through the lens of the Theory of Planned Behavior (TPB) within the context of contemporary digital marketing.
Methodology / approach
An experimental quantitative approach was adopted, combining A/B testing and Brand Lift study. The sample included distinct audience segments, evaluating sales funnel metrics, costs, ROI, brand recall, and favorability in digital campaigns of a hair treatment company.
Main results
The full-funnel strategy outperformed direct conversion in sales, cost reduction, and ROI. However, campaigns focused exclusively on conversion achieved superior performance in recall, top-of-mind awareness, and favorability.
Theoretical / methodological contributions
We expand the application of the TPB in digital marketing, illustrating how various investment allocations influence different stages of the consumer journey. We incorporate conversion and perception metrics, combining experimental and Brand Lift methods within the national context.
Social / management contributions
The findings guide managers in balancing short-term goals, such as conversion, with brand building. They emphasize the importance of segmenting audiences by funnel stage, optimizing resources, and integrating performance and perception metrics to make more assertive digital marketing decisions.
