유튜브 알고리즘: 더욱 인기있는 콘텐츠를 추천
This analysis also illustrates how the site’s recommendation engine steers users toward progressively more popular content as measured by view counts. Collectively, the starting videos in this analysis had an average of just over 8 million views. But the first videos recommended by the algorithm were much more popular, with nearly 30 million views on average. And videos in the final step in these walks had an average of more than 40 million views.
Although the magnitude of the effect is slightly different in each case, this general relationship held true regardless of whether the initial video was chosen based on date posted, view count, relevance or user rating. Even when starting on one of a channel’s five most recent videos (which average fewer than 2 million views) the recommendation algorithm consistently suggested more popular videos. By the fourth recommendation on walks starting from a channel’s most recent videos, viewers were recommended videos with an average of nearly 33 million views.
