What makes a public figure truly effective in advertising?
In a market where brand trust and audience alignment are critical, choosing the right public figure or digital influencer can make or break a campaign. The 2025 edition of Public Figures and Digital Influencers, a study by Marktest, offers data-driven insights into how Portuguese consumers perceive national personalities—and how those perceptions shape marketing effectiveness.
A Comprehensive View of Influence
Based on responses from over 1,200 individuals aged 15 to 64 across mainland Portugal, the study evaluates 150 public figures and influencers. It measures:
- Awareness and identification
- Associations with attributes like credibility, competence, and honesty
- Sector-specific suitability for advertising across 27 industries, including telecom, finance, automotive, and beauty
This approach allows marketers to understand not only who is well-known, but also who is seen as trustworthy and persuasive by key demographics.

Applications for Marketing and Brand Strategy
For brand and media professionals, the implications are significant:
- Audience alignment: Identify which figures resonate most with your target segments
- Campaign relevance: Select influencers best suited to specific sectors or values
- Reputation management: Evaluate the perceived credibility of brand ambassadors
- Conversion influence: Understand the role of influencer-brand association in purchase decisions

Tools for Actionable Analysis
The study is available through two formats:
- A comprehensive report featuring graphical and descriptive analysis plus detailed demographic breakdowns
- An interactive web app that provides visual summaries of each figure’s performance across key metrics, optimized for desktop and mobile use
