Frequently Asked Questions
What does an influencer marketing agency actually do?
An influencer agency builds, manages, and measures collaborative content partnerships between brands and creators to achieve business goals.
How much does influencer marketing cost?
Costs vary by scope, creator tiers, content usage, and campaign length. Most agencies operate on monthly retainers plus creator fees.

Yes — especially for education, trust-building, recruiting, and long-term demand generation.
What makes Fresh Content Society different from other agencies?
Influencer marketing often focuses on reach and endorsement, while creator partnerships emphasize ongoing collaboration and content co-creation over time.

Engagement quality (not just volume)
Traffic and assisted conversions
Content reuse performance
Brand lift or sentiment analysis
Vanity metrics alone are no longer enough in 2026.
Do influencer marketing agencies handle FTC compliance?
Yes, reputable agencies manage FTC disclosure requirements, contracts, usage rights, and brand safety guidelines. If an agency does not proactively address compliance, that is a red flag.

Influencer marketing is effective across:
Consumer packaged goods (CPG)
Fitness and wellness
Automotive and motorsports
Construction and skilled trades
Manufacturing and industrial brands
