Qualify YouTube creators using engagement, posting activity, public contacts and sponsorship disclosures.
Analyzes lists of YouTube creators to qualify and rank prospects for sponsorship outreach by measuring real engagement and sponsorship behavior from recent uploads. The connector computes average views and a true engagement rate (likes plus comments divided by views, averaged across recent uploads), detects sponsored content via disclosure language in titles and descriptions, and tallies sponsorship frequency as both a count and percentage of recent videos. It extracts public business contact emails from channel descriptions, captures titles of videos that disclose paid partnerships or #ad, and combines engagement, reach, sponsorship experience, and contactability into a composite sponsorship fit score (0–100) with tier labels for shortlist filtering. Outputs are per-creator records containing channel basics, recent-performance metrics, sponsorship history and mentions, contact emails, fit score, and tier; it can process large lists in a single run and includes a deterministic sample mode for integration testing.
