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.
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.
Keep in mind, this will often mean shifting the focus of your business from more general to more specific products or services. For instance, instead of exclusively offering general home renovation services, you could consider specializing in "one day bathroom renos" or "custom kitchen makeovers." These more specific keyword phrases will likely be much easier to rank for, which will mean you can start ranking that much faster.
