For business owners and Internet marketers, YouTube presents a unique way to build upon their existing client base through promotional videos. Running a successful promotional campaign on YouTube, however, involves more than simply uploading a video and waiting for the view count to grow. In fact, one of the greatest difficulties faced by YouTube users is to attract enough viewers to make their promotional campaign effective. The most effective YouTube videos are those that reach the largest audience, as more potential customers will see the video. The more views a video has, the more likely the average user will watch it instead of another video with far fewer views. In addition, the more viewers a video has, the more likely it will be that viewers will share the video with other potential customers. Lastly, search engines tend to give preference to those videos with the highest view counts, giving the video further exposure to other potential clients.
