This value puts the number of likes in relation to the number of views of the video. The bar chart shows the comparison of influencers with a similar number of subscribers. A high value indicates that a large number of viewers actually watch the video and that the users really like the video. YouTube no longer shows the number of dislikes, so a low score can be expected to indicate a high number of dislikes. 

Calculation: median [video (number of likes) / video (view count)]. The last 12 videos are taken into account.
