Adding video to your website is a fantastic way of interacting with your audience and “informing” or “selling” to them. Beyond the benefit of a video being informative and engaging for your audience, video is important for website SEO in many other ways.
There are a couple really important elements to video beyond information, in simplest terms, search engines will often “time” how long a person stays on your website or on a particular page, the longer they are on the page the more value the search engine will assign to that particular page. If you’ve got a quick 30 second clip on your site that people watch or even watch a part of it means they are spending more time on that particular page thereby giving your page more value to the search engines.
BE SURE that when you create your video, if you choose to host it on a video hosting site that you link back to your content from the video webpage. In most cases this is free.
