When designing an influencer campaign timeline, you should consider the following factors:

1. Campaign Goals: Define what you want to achieve. This could be increasing brand awareness, driving web traffic, or generating sales. This will help set appropriate timeframes for campaign commencement, assessment, and conclusion.

2. Influencer Discovery and Engagement: The time taken to identify, reach out to, and negotiate terms with influencers can vary. Utilizing influencer marketing platforms like Flinque can help streamline this process and save time.

3. Content Creation and Review: Content needs to be thoughtfully crafted, reviewed, and revised if necessary. Allocate time based on the complexity of the content, and the iteration and approval process.

4. Campaign Launch and Duration: Depending on the scope of your campaign, you might need a short burst for product launches or longer campaigns for brand building.

5. Analysis and Report: Include time for analyzing results against set KPIs and creating detailed reports. Platforms like Flinque offer comprehensive data analytics tools that make these analyses more efficient.

6. Seasonality: Consider the time of the year. Is it a holiday season when users might be more engaged, or a quiet period when your message could stand out?

Remember, timelines can vary greatly depending on individual campaign specifics. The key is to prepare well and remain flexible to adjustments as they arise.
