I have noticed that for some videos most of their referrers/embedders are weird looking websites? What's the deal with those sites, are these "aggregator sites" or are there called something else? For example this video: has 260 referres and 29 embed sources.. The first 2 referrers are said youtuber's facebook page, but other than that all of them (or at least the ones I can see with VidIq basic) are from these kind of sites.. So can I contact these sites to refer/embed my videos too? Or do they do it automatically for the videos they want?? Do they really help make your video viral OR is it the other way around, they see a viral video and then refer/embed it? Thanks for your help, and I know this is probably a very noob question but is something I have been wondering for a while. EDIT: Changed the video because the thumbail of the last video I posted wasn't SFW, but this is.
