The most expensive influencer marketing mistake isn't picking the wrong creative angle — it's paying a creator whose audience was never real to begin with.
Signs of fake or purchased followers
A sudden, unexplained spike in follower count, an engagement rate that's implausibly low or suspiciously uniform across every post, and a follower base concentrated in countries far outside a creator's stated audience are all common red flags worth checking before signing anything.
Engagement pods and inflated interaction
Comment pods — groups of accounts that comment on each other's posts to inflate engagement — tend to produce generic, interchangeable comments ("Amazing! 🔥", "Love this!") posted within minutes of each other. A quick scroll through recent comment sections often reveals this pattern immediately.
Brand safety goes beyond follower quality
Reviewing a creator's posting history for content that conflicts with your brand values, past controversies, or inconsistent messaging matters as much as audience authenticity — a creator with a perfectly real audience can still be the wrong fit if their public history creates risk.
Building vetting into your process
Vetting should happen before a contract is signed, not after a campaign underperforms. A short, consistent checklist — audience authenticity, engagement patterns, content history, and past brand partnerships — catches most issues early.
Vetting is a standard part of how our influencer marketing team sources creators — not an optional add-on after a campaign is already underway.
