We know that consistent quality of content continues to be a very important ranking factor for Google, and producing consistent quality video content is another way of proving to the search engine that you're a committed expert on your chosen topics. Video content is a great way to build up authority and relevance over time. And it's been shown that the chances of getting a page 1 search listing on Google increase 50 times with video.
One video is great, but the more often you post engaging video, the better. It may not be realistic to post videos every single day or for every single initiative, but if you’ve got a major campaign you’re working on or an initiative that would really benefit from video, dedicate some resources to video creation. Even overlaying text on a piece of stock footage can be highly engaging on your website and bring more visitors from organic search.
