Adapting campaign planning when dealing with different social media platforms requires a strategic approach where you consider the unique attributes, audience demographics, and engagement styles of each platform. Here are a few best practices:

1. Understand Platform-Specific Demographics: Different platforms attract different age groups, interests, and uses. Instagram, for example, is popular among younger demographics and focuses on visual content, while LinkedIn is geared towards working professionals, with a content strategy centered around networking and industry news.

2. Customize Content for Each Platform: A post that works well on Facebook might not yield the same results on Twitter due to character limit differences, content preferences, and user behavior. Tailoring content for each platform can be beneficial.

3. Leverage Platform-Specific Features: Utilize each platform’s unique tools. For example, Instagram offers shoppable posts and stories while LinkedIn provides Sponsored InMail for direct communication.

4. Analyze Performance Across Platforms: Use analytics to understand the performance of your campaigns on different channels. This data can inform where to concentrate your efforts.

5. Align with Influencer’s Audience on Each Platform: An influencer’s following might vary from platform to platform. Ensure the influencer’s audience aligns with your target demographic across the selected networks.
