Influencer campaigns: how a campaign is run, from brief to report

The global influencer marketing market was worth 32.55 billion dollars in 2025 (Influencer Marketing Hub). Yet a successful campaign rests on simple things: a clear brief, the right casting and KPIs set in advance. Here is how STAKRN runs a campaign, step by step.

1. The brief

Everything starts here. We ask for your objective (awareness, downloads, sales, recruitment), the target, the messages, brand and regulatory constraints, the budget and the timeline. A one-page brief beats a forty-page file. If the question is still which lever to pull, start with the activation strategy.

2. Casting

We submit a reasoned selection of creators. For each one: the size and make-up of the audience (age, country, platforms), real engagement, past partnerships and the recommended format. A creator who worked with your direct competitor last month is not a good choice, even with great numbers.

3. The framework

Contracts, content usage rights, approval workflow, publication calendar. For campaigns in France, we also apply the law of 9 June 2023 on commercial influence: every sponsored piece of content carries the label « Publicité » or « Collaboration commerciale », and some products are banned or restricted.

4. Production and publication

Creators keep their own voice. That is where a campaign’s value lies: their communities spot a scripted ad straight away. The brief sets the message and the must-haves, the creator chooses how to say it. A Twitch live, a YouTube video, a short on TikTok or Shorts, an Instagram post: each format has its own logic and rhythm.

5. Reporting

At the end of the campaign, you receive consolidated figures: views, reach, engagement, clicks, code redemptions and conversions where they can be tracked. They are compared with the brief’s objectives, along with what we would repeat and what we would change.

Frequently asked questions

How many creators does a campaign need?

Anywhere from one to several dozen. HelloFresh worked with 2 creators, Eneba with 17. The right number depends on the objective: awareness needs coverage, conversion needs highly targeted communities.

Can we reuse the content in our ads?

Yes, if usage rights are included in the contract: duration, media, territories. It is better to negotiate them from the start, they cost less than afterwards.

What happens if a piece of content does not follow the brief?

Every piece of content goes through approval before publication. The workflow and deadlines are agreed before production.
