The audience growth rate is the subscriber growth over time, expressed as a monthly percentage based on the channel's subscriber history.
As on the other platforms, growth is benchmarked against channels of similar size for the score, so niche channels and mainstream channels are compared fairly.
In detail, the growth score looks at the subscriber growth of the last 30 days: influData compares the current subscriber count with the count 30 days ago. The horizontal bars in the app show how this growth compares with channels of a similar subscriber count.
In influData's experience, growth is the most meaningful single signal for judging the quality of a channel: strong subscriber growth correlates positively with most other scores and is a reliable indicator for campaign success. That is why the growth score deserves extra attention when you evaluate a YouTube creator.
