Virtual Influencers Drive Eco-Conscious Consumer Commitment Through Perceived Attractiveness and Similarity

Virtual influencers can foster strong consumer commitment to sustainable brands by leveraging perceived attractiveness and similarity, leading to increased eco-conscious purchase intentions.

Sustainability · 2025

Key Findings

01Virtual influencer characteristics significantly predict relationship commitment.
02Perceived similarity and attractiveness are the strongest predictors of relationship commitment.
03Relationship commitment mediates the influence of virtual influencers on sustainable brand attitudes and purchase intentions.
04Consumer innovativeness positively moderates the effects of virtual influencer characteristics, particularly attractiveness and para-social interaction.

Application

Design takeaway

How to apply

Brands can create or select virtual influencers whose visual design and communication style align with target audience preferences for attractiveness and similarity, specifically within the context of promoting environmental stewardship.

Project actions

01Consider creating a virtual persona for a sustainable product and test its appeal based on attractiveness and similarity.
02Explore how different levels of consumer innovativeness might affect engagement with a virtual influencer promoting an eco-friendly initiative.

Method & Evidence

AimTo investigate how virtual influencer characteristics (expertise, similarity, attractiveness, familiarity, para-social interaction) influence consumer commitment and subsequent eco-conscious brand engagement, moderated by consumer innovativeness.

MethodQuantitative research using structural equation modeling (SEM).

ProcedureA survey was administered to 677 participants actively engaging with sustainability-focused virtual influencer content. Data was analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) to test the proposed relationships between virtual influencer characteristics, relationship commitment, sustainable brand attitudes, and purchase intentions.

Sample677 participants

ContextDigital marketing, influencer marketing, sustainable consumption, AI-generated personas.

Variables

IV["Virtual influencer characteristics (expertise, similarity, attractiveness, familiarity, para-social interaction)"]

DV["Consumer commitment","Sustainable brand attitudes","Purchase intentions for environmentally responsible products"]

CV["Consumer innovativeness (moderator)"]

Strengths & Limitations

Strengths

+Large sample size providing statistical power.
+Use of established theoretical frameworks (computer-mediated communication, social psychology).

Limitations

The study's findings might be specific to the digital platforms and types of sustainable products examined. The long-term impact of these relationships is not fully explored.

Reliability & validity

The study employed established SEM methodologies (EQS, SmartPLS) and a large sample size, contributing to the reliability and validity of its findings regarding the proposed relationships.

Think critically

To what extent can the perceived 'attractiveness' and 'similarity' of a virtual influencer be objectively measured and replicated across diverse cultural contexts?

Design Principles

"Perceived similarity and attractiveness in AI-driven personas can cultivate parasocial relationships that translate into tangible consumer commitment and behavioral shifts towards sustainability."

As digital marketing evolves, understanding how AI-driven personas influence consumer behavior is crucial. This research highlights a pathway for brands to leverage virtual influencers to promote sustainability, impacting product development and marketing strategies.

What This Means for Your Design

Virtual influencers can make people care more about eco-friendly brands if they look good and seem relatable, especially if the person is open to new things.

How to use in your project

1.Use this research to justify the design choices for a virtual character intended to promote a sustainable product or cause, linking design attributes to predicted consumer response.

Paragraph starter

This study by Diao et al. (2025) demonstrates that virtual influencers can significantly enhance consumer commitment to sustainable brands by leveraging perceived attractiveness and similarity. Their research indicates that these characteristics foster parasocial relationships, which in turn positively influence attitudes towards eco-conscious brands and subsequent purchase intentions. This provides a strong theoretical basis for designing virtual personas intended to promote environmental stewardship.
