  Greg Bellan: Question for the group. If I embed someone else's video (relevant to the content on my page) and add a transcript of this video, is there any negative SEO associate with this?  ;The video content in question isn't necessarily mine, but it's absolutely relevant to other content on my site. Any thoughts?  ;Guidelines on how best to handle this situation?

  Jim Munro: I don't think so, Greg, but I do not know for sure.
  
  There are about 20 sites doing more or less the same thing to dumbseoquestions (dot) com and I think it might help us more than it hinders us. It must at least expose us to a wider audience.
  
  It does not seem to be doing them any harm , anyway.

  Dave Elliott: Personally id give them a link saying where it was from originally, but, I cant see any harm as long as yoh aren't implying it is your video.

  Matt Staton: Biggest concern would be copyright infringement.
  
  Good SEO play.

  Matt Staton: Also use Schema.org markup too.

  SKI USA INC: 1) I think you must contact with the person who has originally shared and informed him/her that you have embed his video for your blog.
  2) Mentioned him in your content as a reference for your blog.
  3) Give his part of credit by giving a back link or mentioning him.
  This will prevent you from penalising your website. Thanks
