Understanding influencer marketing: The role of congruence between influencers, products and consumers
Daniel Belanche, Luis V. Casaló, Marta Flavián, Sergio Ibáñez-Sánchez (2021). Understanding influencer marketing: The role of congruence between influencers, products and consumers. Journal of Business Research. https://doi.org/10.1016/j.jbusres.2021.03.067.
Plain-English take
Follower–product congruence produced more favorable product attitudes; attitude increased purchase and recommendation intentions. For your marketing: Use as a behavioral mechanism or experiment-design reference, not a direct forecast for a SaaS funnel.
How much weight to give this
4/5 Strong design for its specific question
The 1–5 evidence-check score is a practical reading aid, not a formal peer review or a probability that a conclusion is true. It combines design strength (2 points), sample reporting (1), comparison/control clarity (1), and how much of the paper could be checked (1). Access affects how confidently this directory can assess a study, not the study's underlying quality. Blinding is reported separately because it is not relevant to every design.

Research question
What the authors investigated
When and through what mechanism does congruence among influencer, product, and follower affect responses?
Design
Experiment with followers of a top fashion influencer; factorial manipulation of influencer/product/consumer congruence.

Scope and transfer
Limitations to keep in view
The publisher describes an experimental, single-influencer fashion context, so generalization beyond that context is limited.
Possible founder application
Use as a behavioral mechanism or experiment-design reference, not a direct forecast for a SaaS funnel.
Evidence access
Publisher record and abstract retrieved; consult the linked paper for full methods and tables.
Publisher highlights explicitly state the experimental design, n=372, positive congruence effect on attitude, and downstream purchase/recommendation intentions. Direct publisher-page retrieval was recorded on 2026-10-09; this profile uses the publisher abstract/metadata and does not claim independent review of unavailable full text.
If only an abstract or metadata was available, the profile is limited to claims supported there. A paper's paywall does not change its evidentiary status, but it limits what we can substantiate from accessible text.
