Creating a comprehensive brief for an influencer campaign requires a clear and objective approach. Here’s how you can set out expectations:

1. Campaign Overview: State what your campaign is about. This could include the purpose, product, or service you’re promoting.

2. Clear Objectives: Are you looking to increase brand awareness, push product sales, or foster engagement? Defining clear, measurable objectives are crucial to assess the eventual performance of the campaign.

3. Influencer’s Role: Describe what your influencer will do. This could vary from product usage, product reviewing to creating compelling stories around your brand.

4. Content Guidelines: Detail what content should be created-mentions, hashtags, visual guidelines, and the tone of voice required.

5. Performance Metrics: Define metrics by which you’d be measuring the influencer’s performance. These might include likes, shares, overall reach, website visits, or sales generated.

6. Deadline and Timeline: Provide clear deadlines for deliverables to ensure the campaign runs smoothly and timely.

Regular communication is key to making sure your campaign stays on track. For this purpose, you can use platforms like Flinque which offer you the tools to manage your campaign in one place. Flinque helps you brief your influencers, track their progress, and measure their effectiveness along the way. But remember, the appropriateness of Flinque or any other platform largely depends on your specific needs and requirements.

Finally, after the campaign, it’s essential to review the objectives and performance metrics to learn from the experience. This way, you can continually refine your influencer marketing efforts for even better results.
