Hey Eddy, my name is Stanford Pelage I am a YouTube and Google seo expert. I’ve made several comments on this thread and I would suggest that you went through the entire comments and look click ctrl f and type mrpelge and read all of my comments, that would drastically help you. The thing about YouTube Google rankings since April 2014 Google had a major update, many vseo have been crying but the solution is pretty simple. Treat your important videos like a website, don’t over optimize and don’t keyword stuff. Everyone says to do long articles, I would recommend a 1,000-1,500 word unique article for YouTube videos with a lot of competition. Don’t spam your video filename, don’t spam the tags. Just 3-5 tags would be sufficient. Main keyword,main keyword with an s and an lsi keyword and what your product does would be perfect, don’t want to confuse Google, that represents spam.
One of my favorite ways to give content a boost is to run ads on Facebook targeting people with interests that are relevant to the content. It’s fairly low cost since you are offering a free piece of content. By targeting people with relevant interests to your content, you drive the right people to the content and into the top of your funnel. And if your content resonates with them, they’ll share, link, and engage with the content in ways that will help Google see its value.
