There is an extreme importance placed on the number of view you get for any given YouTube video you produce and post. Numbers of reasons or singular reasons could exist for your actual purpose. Generally, the idea is to get views. If this is not something you actually care about and you simply posted the video without expecting views that is fine. On the other side of things, if you are seeking more views for a good reason, then you may need to buy youtube views first before you can begin getting more views.
This is actually a very simple principle and the same is true for all social media. Social media is not free. We think we can freely advertise on it and we can try, but the actual views and likes and comments come with a price. This is especially true for videos on YouTube since there are usually so many selections with the same title, most people look for number of views and a specific image to match up to what they are looking for.
The number of existing views on any given YouTube video post is one of the main motivating factors for someone to actually watch it. Since you will be using the video for promotional purposes, it is worth the investment to work with one of the better services for YouTube view purchases. They do their work on a discrete level so it is real and there is no evidence of doctoring your video.
Generally, services are offered in view bundles at certain costs per number of views. These views are posted over a period of time so as to avoid appearing completely contrived. After a period of time, all of the views are on and hopefully new views will be the result since it does appear the video is rapidly gaining popularity.
