Professor Osmar Castro's estimated sponsorship rates

The estimated rate for an integrated video on Professor Osmar Castro's YouTube channel ranges from $157 to $393, with a typical rate around $262. This places Professor Castro in the low audience tier based on subscriber count. Several factors influence this rate, including his niche specialization in dental prosthesis, which can command higher CPMs due to its professional and educational focus. The specific format of an integrated video, which involves a brand message woven into the creator's regular content, also impacts pricing. While the primary language is not specified, his base in Brazil may also be a factor in regional CPM variations. Compared to general health channels, a highly specialized medical or dental channel often attracts brands seeking a precise audience, which can push rates higher within a given subscriber tier. The current estimate is based on an algorithmic model, without community data points for calibration at this time.
