Ron, Google just had some major updates, avoid buying any type of views. Like I previous said, high pr backlinks is what you need. Best practice is using about 5 do follow web 2.0 properties to link directly to your YouTube video, and build all backlinks to your 5 web 2.0 properties so if your video gets deleted from buying views you still have all that backlink juice that you can redirect to the new video.
One of my favorite ways to give content a boost is to run ads on Facebook targeting people with interests that are relevant to the content. It’s fairly low cost since you are offering a free piece of content. By targeting people with relevant interests to your content, you drive the right people to the content and into the top of your funnel. And if your content resonates with them, they’ll share, link, and engage with the content in ways that will help Google see its value.
