Would you recommend using YouTube for Video SEO purposes?
The short answer: no. We would prefer Wistia, Vimeo, Blip or Dailymotion. While YouTube works at the moment, it might break if Google decides they want to send the traffic to YouTube instead of your site. Thus we would advise against using it for Video SEO purposes. It is however a great site to get found on as well, so if you've got the resources for it, upload it to both YouTube and another video platform of your choice and use that second video platform for embedding on your blog.
