What's the difference between an influencer platform and an agency?

A platform is a software tool (SaaS) that you and your team use to manage campaigns yourselves, while an agency provides a managed service, handling strategy, execution, and reporting for you. Some platforms offer managed services as an add-on, but the core product is the software.

How do you measure the ROI of influencer marketing?

ROI is measured by comparing the campaign's return to its cost. For e-commerce, this is often tracked via sales generated from unique discount codes or affiliate links. For awareness, metrics like Earned Media Value (EMV), impressions, and engagement rate are used to assign a monetary value to the campaign's reach.

Are there free influencer marketing platforms?

No, there are very few truly free end-to-end platforms, as the data and features are costly to maintain. Some offer a limited free tier or free tools for specific tasks, like a simple influencer search or a campaign calculator, but full campaign management and analytics always require a paid subscription.
