Fig. 7. — Weighted proportion of referrals to YouTube videos of each channel type by referrer type for on-platform referrers (A) and off-platform referrers (B). All data include 95% CIs, though these are sometimes not visible because of the sample size of the referrals data (unweighted N = 1,013,692)]. Other on-platform platform referrals such as YouTube playlists and personal user pages were grouped into a separate category. Similarly, off-platform domains that do not fit into any of the labeled categories in (B) are grouped together. A list of all domains included in each group can be found in the Supplementary Materials.
