Hey Brian That was a great article ! I was always curious about Youtube SEO and its quite detailed I’ll try to write the main points in my notepad so I can remember this checklist when doing Youtube Seo 🙂 The tutorial is also quite helpful ! I agree with you on the queries google uses for showing video results, that makes sense now why google shows videos on “How to” queries.
What about subtitles & closed captions? I see in one of your comment replies that you’ve uploaded transcripts of your videos but looks like Youtube has 1 spot for transcripts and another for subtitles/CC. Have you tested both transcripts and subtitles/CC? Also, I know the difference between subtitles and CC but there doesn’t appear to be anyone that’s tested once vs the other. Might be something to test.
i have never read an informative post until i came across this and am hooked. Helped me recognize broken links that i had no idea where sitting there. Also right in the beginning about having link worthy site, its like you were talking to me about writing see the link "here" and the LSI was a good tip i knew nothing about. Thank you so much and all the best.
As keywords are essentially the backbone of on-page SEO, you need to pay a lot of attention to them. There is no reason not to include them in your URLs.  The inclusion has its benefits. When you assimilate the targeted keyword into the URL, you are ensuring that Google’s has another reason and way to consider your article as more relevant for a particular phrase.
Just to be clear. 100-200 views just to give your video that presence, (nobody wants to be the first person to watch your video) 3-5 days after you upload it in the span of 25-50 views a day until you at 100-200 views. Then just keep building quality links then everything else should be natural especially the traffic. Or what’s the point? Have a video getting 100 views per month making me $500. Keyword research should be your main concern, then rankings come easy.

It appears that the reason this page from a little-known website is able to rank amongst the bigger players is that the content itself is more focussed. It talks about how to name images for SEO, whereas most of the other pages are more general guides to image SEO—which all presumably mention the importance of naming images correctly, amongst other things.
