Scores are built only from public, citable evidence such as case studies, press, and interviews. Placement cannot be purchased, and sponsored listings are labelled and never re-ranked.
- What should I look for when choosing a influencer marketing agency?
- Look for FTC-compliant disclosure practice, negotiated usage rights, whitelisting or Spark Ads capability, and reporting on cost per acquired customer rather than reach. Beyond that, confirm the budget band matches yours and that the senior operator named in the pitch is the person who will actually run the account.

- Most reputable shops want $20k–$50k/mo in total program spend, covering talent fees, paid amplification, and the agency fee. Management fees typically run 15–25% of talent spend. Every profile in this index lists the agency's disclosed budget band so you can filter before the first call.
