Great post! You just gave me an idea for another passive income stream. I haven’t had any experience with building backlinks in to YouTube vids, but I think that the sheer authority of YT that the internal links alone makes it easier to rank for moderately competitive keywords compared to websites, the farthest I’d go is share it in social media. The key is getting it indexed.
Great article. These are guidelines I usually follow and this helps explain it a bit better for me. I do have a question about the description. When you say “Put your link at the very top of the video”, are you talking about the link to the youtube video or link or your website? My co-worker likes to put in the youtube link that goes to the same video in the description. Does that help?

But sometimes there are site-wide technical issues that get in your way of ranking on Google. Luckily, fixing technical issues is not a required step for every single piece of content you create. However, as you create more and more content you should be aware of duplicate content, broken links, or problems with crawling and indexing. These issues can set you back in search results.
