Influencer Marketing and the trust issue
Influencer marketing has exploded into a $24 billion industry and it’s showing no signs of slowing down. But beneath the growth, marketers are facing an uncomfortable reality: the more the industry scales, the more consumer trust erodes. That’s the sobering conclusion from Harvard Business Review (HBR).
We wanted to understand what people actually think about influencers, not what brands hope they think. So we went out to the streets to talk to consumers. While the research sample size isn’t statistically valid, the results were still telling.
Most consumers over 40 said influencers simply don’t move the needle for them. Among those under 40, the story was more nuanced: big-name celebrity endorsers like Beyoncé, Drake, and Hailey Bieber (Rhode) carry weight. But so does product quality. Younger consumers may be swayed by a celebrity co sign, but they won’t come back if the product doesn’t deliver. The endorsement gets the first purchase. The product has to earn the second.
That tension sits at the heart of a wider problem HBR has been tracking. Research shows that 88% of consumers say authenticity matters to them when following influencers yet nearly half believe most influencers perform a version of themselves rather than being genuine.
More than a third think influencers routinely misrepresent the products they promote. The result is a fraying ecosystem: consumers feel misled, influencers struggle to remain authentic under brand pressure, and many marketing managers still haven’t cracked the code on what authenticity actually requires.
What Authenticity Really Means
To get at the root of the problem, HBR conducted a large-scale study drawing on 185 interviews with brand managers, agencies, influencers, and consumers across five continents. The key insight: authenticity isn’t a fixed personal quality; it’s something that gets built (or broken) through ongoing interactions between influencers, brands, followers, and agencies. And according to HBR, it hinges on alignment across five dimensions:
- Expertise — The influencer is seen as genuinely knowledgeable in their space.
- Connectedness — Followers feel a real emotional familiarity, not just passive viewership.
- Integrity — The influencer’s choices appear driven by care for their audience, not just a paycheck.
- Originality — The content has a distinct voice that couldn’t belong to anyone else.
- Transparency — Paid partnerships and honest experiences are disclosed openly.
Each stakeholder weighs these differently. Consumers care most about integrity and transparency. They want to know the influencer actually believes in what they’re promoting. Influencers themselves tend to prioritize originality and expertise as the foundations of their identity. Meanwhile, brands often default to optimizing for reach and message control, which – as HBR points out – can quietly undermine the very authenticity that makes influencer content compelling in the first place.
Where It Breaks Down
When these priorities fall out of sync, the ecosystem suffers. Brands that over-script content or chase short-term ROI strip away the spontaneity that makes influencer voices credible. Influencers who hide their commercial relationships often out of fear of being labeled sellouts actually do more damage to trust than those who disclose them clearly. HBR’s research is unambiguous on this point: transparency doesn’t erode authenticity. It builds it.
For CMOs, the implication is straightforward even if the execution isn’t: stop treating authenticity as a vibe and start treating it as a set of measurable dynamics. HBR concludes that the influencers who perform best over time aren’t those with the most followers or the cleanest aesthetics; they’re the ones whose audiences believe them.
