People search for video
From the search end of things, people can search for video on its own. Google has a function that lets you search maps, pictures or video, among many other things. Your website is likely to attract more visitors if it contains a video than if it doesn’t.
So the more videos you have on your website, the more visitors you are likely to get and the more likely it is that visitors will play them, making search engines take notice. The more captivating the video, the more plays it will get and the more time people will spend on your website. Not only does this attract more people to your website more often, but your ranking on search engine results pages will go up. Notice a trend here? Another good reason to do more with your video.
