ORM and YouTube - my experience

I am just practicing now.

I've made a fictitious company name to test my SEO skills. From 5 different YT accounts, from different computers, I can get 1-2 of my videos to rank on the web search results but then the other 3 videos only appear in video search results (which are really invisible unless someone sees the video results). Do you understand what I've done? Any opinions please? Obviously my goals are get all YT videos to publish and rank on the web search results of Google. Thank you.

Testing is always great! I test everything, that's the only way to know what's effective.
