Video creators readily purchase views, by the thousands, as well as fake likes. By doing this, Google pushes their videos higher up in search rankings and in recommended video lists.
Essentially *all* of the Youtube stars who got started in the earlier years (which is most of today’s Youtube stars) used fake views to inflate their viewership. Back then it was incredibly easy – you could put a Youtube video player one hundred times on an HTML page and each time the page was reloaded, it would add 100 views. Tricks like that were shut down long ago.
Now, YouTubers just buy views to help establish their channels. The reason is because there is vast amounts of content on Youtube now – and its extraordinarily difficult for new channels to get underway. I read it can take 3 or more years of steadily posting videos before a new channel will have much of a following. You need something to “hook” the reader, from unusual/odd to young and cute.
