When bots visit your site, they see a big black hole where that YT video is, and that's bad, not to mention ugly. Let me create the proper Schema code for you which allows the inclusion of a video on your site with all types of detail. It's how I get my videos to pump up views as well, my websites to rank.
I use videos in pages and also for vid posts - what better than to make sure they're properly online?
So if you were thinking of simply copying and pasting the code from YT, stop. It helps when your YouTube vids are properly set for Schema.
All I need from you is the link to your video. You'll get the code to copy/paste onto your web page or blog post.
THIS GIG ALSO WORKS FOR VIMEO VIDEOS!!!
