Generate a detailed blueprint for influencer collaborations, outlining strategies for different marketing campaign types.  The blueprint should cover various influencer tiers (nano, micro, macro, mega), platforms (TikTok, Instagram, YouTube, Twitter, etc.), campaign goals (brand awareness, lead generation, sales), and budget considerations.  Include sections on influencer selection criteria (audience demographics, engagement rate, brand alignment), contract negotiation, campaign execution (content creation, scheduling, promotion), and performance measurement (metrics, reporting).  Provide examples of successful influencer campaigns across different industries and platforms.  The output should be formatted as a structured document with clear headings and subheadings, including tables and checklists where appropriate.  Success will be measured by the comprehensiveness of the blueprint, the clarity of its instructions, and the inclusion of practical examples and actionable strategies.
