Especially when it comes to videos, people are a lot less inclined to leave the website if a video has started playing when they open up your landing page. It peaks their interest and oftentimes keeps them on the page for a while longer. Having a high bounce rate is something you definitely want to avoid as it implies that either your website or product is lacking in some way. If high bounce rates have been crippling your brand's success, implementing rich content can thoroughly help your site. Viewers will stay on your site for as long as possible! This increases the chances of them purchasing something on your site.
