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.
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.
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.
