Influencer marketing disputes have matured into a recognizable litigation category with four recurring fact patterns: unmet deliverables, FTC disclosure failures, engagement or audience fraud, and contract scope fights over content ownership and exclusivity. As brand deal values have grown, so has the money at stake when they collapse — and courts increasingly see cases where the central evidence is analytics data neither judge nor jury has ever read before.
I've worked as an expert in influencer marketing disputes, and the influencer economy is where my two backgrounds converge: I built social media campaigns at scale professionally before I ever testified about them. Here's the map of this litigation category.

Influencer dispute damages typically build from one of three anchors: the contract value (fees paid for performance not delivered), market rate analysis (what the promised audience and engagement would cost at genuine market prices — which requires credible sponsorship benchmarking), or attributed revenue impact (tracked sales, promo-code redemptions, and traffic the campaign did or didn't produce).
Each anchor has an expert-analysis layer: establishing what performance was actually delivered, what the authentic audience actually was, and what comparable campaigns actually cost.
Influencer evidence is unusually perishable: stories expire in 24 hours, posts get deleted or edited without notice, and insights data is visible only to the account holder. By the time a dispute matures, much of the record exists only in whatever screenshots and exports someone thought to capture. Preservation demands in influencer cases must be platform-specific and immediate — covering insights/analytics exports, story archives, and draft approvals, not just "posts."

Courts don't know what a "good" engagement rate is, whether 3% story completion is success or failure, or what a mid-tier beauty creator's sponsorship actually costs. An expert supplies the benchmarks, authenticates the analytics, evaluates audience authenticity, and translates campaign performance into terms a fact-finder can weigh — on either side of the v.
Most commonly: unmet deliverables, FTC disclosure failures, engagement or follower fraud, and contract scope issues like content ownership and exclusivity.
Through engagement-rate benchmarking, follower auditing, and growth-pattern analysis — sudden spikes, inauthentic follower profiles, and engagement inconsistent with audience size.
From contract value, market-rate analysis of the promised versus delivered audience, or attributed revenue impact — each requiring expert benchmarking to survive scrutiny.
Everything perishable, immediately: insights and analytics exports, story archives, post histories including deletions and edits, DMs and approval threads, and the underlying contracts.
