If you want to be ahead of YouTube, you need to promote your video posts as aggressively as possible. In addition to the undeniably important quality of your videos, it's also about social evidence.
YouTube Likes say something about whether your videos get approval. Clips with a higher number of YouTube likes automatically assume a higher quality. This increases both the ranking and the likelihood that your video will be watched. But remember, if you do not keep this promise of quality, your purchased YouTube Likes will of course miss out.
