YouTube Creator Sponsorship Intelligence

YouTube

Operated by Sourcelane✓ verified

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.
