# Influence agency: how to choose one and at what price?

**In short:** an influence agency designs and runs campaigns with content creators, from strategy to measurement. It brings bespoke support, where a platform mainly tools up autonomy.

## What an influence agency does
- **Strategy**: define objectives, target, type of creators.
- **Selection**: identify the right profiles (affinity, real audience, values).
- **Creative & brief**: frame content while preserving the creator's freedom.
- **Management**: contracts, usage rights, schedule, compliance (partnership transparency).
- **Measurement**: reach, engagement, and ideally business impact.

## How to choose one
1. **Check its references** in your sector.
2. **Ask about its creator-selection method** (how does it avoid fake followers?).
3. **Clarify measurement**: which metrics beyond views?
4. **Frame transparency**: paid partnerships must be disclosed (mandatory).

## Pricing models
Agencies charge a **flat fee per campaign**, a **retainer**, or a **margin** on creators' fees. The overall budget depends mainly on the number and fame of the creators involved.

## FAQ
**Influence agency or platform?**
The agency for strategy and bespoke work; the platform for autonomy and volume. The choice depends on the operation's complexity.

**How much does an influence campaign cost?**
Highly variable: from accessible micro-campaigns to operations with high-profile creators. Creators' fees are often the first cost item.

**How to ensure compliance?**
By clearly disclosing paid partnerships — a legal requirement and a trust signal.
