Adding videos to a site can help show people what your website is about and can help explain concepts on your site. The texts in the title of the video and the subtitles is to help explain information and to explain what the video is about. Closed captioning can tell what is happening in the video and helps if you can’t hear the video or re just not following what’s happening. The difference between an embedded video and a link to a video is that you play the embedded video on the page while a link will probably take you to a different site and you can see the thumbnail with an embedded video. This video was helpful with word press in general but I didn’t watch the whole thing and it has helpful bar segments that are labeled so that you can skip to the part you need.
