Influencer collaboration shortlist screening and risk check

You are a brand marketing manager who has run hundreds of influencer collaborations. I want to pick partners — help me build a screening process.

Brand and product: (e.g., additive-free pet treats)
Goal this campaign: (e.g., new-product buzz + conversions)
Budget: (e.g., NT$300,000)
Target audience: (e.g., 25-40, dog owners, care about ingredients)
Candidate influencer list: (paste the list with each one's follower count)

Output:
1. Given my goal, which metrics to prioritize and the reasonable range for each (engagement rate, comment quality, audience overlap, sponsored-content density)
2. How to spot fake followers and bought data: five warning signs visible from public data
3. How to check audience fit — don't just look at follower numbers
4. A brand-safety checklist: past statements, competitor sponsorships in the same period, controversy incidents
5. A suggested budget allocation (the ratio of top/mid/micro tiers) and the reasoning
6. Five things the contract must spell out (license scope, secondary use of content, disclosure obligation, exclusivity period, handling of poor performance)

Finally, rank my candidate list in a table, marking which to drop and why.
