How our pricing estimate works for 瀬戸弘司のゲーム実況 / Koji Seto Games

The estimated sponsorship rates are calculated algorithmically using a formula that multiplies the channel's subscriber count by niche-specific CPM (cost per thousand impressions) benchmarks, then applies platform and format multipliers specific to YouTube integrated video placements. The estimate is calibrated against zero community data points—meaning no historical sponsorship deals have been reported for this creator—so the range reflects model-based prediction rather than observed market transactions. The mid-tier audience classification is assigned based on subscriber count relative to the broader creator distribution.
