Quick question for you…do you advise people have their videos transcribed so that search engines can pick-up keywords (or should them simply place keywords in title and description)?
Absolutely! I suggest to paste transcriptions in the blog post where you embed the video player (or audio player if a podcast).
It’s good for the search engines AND also helpful for people who don’t want to watch/listen to the whole recording.
Typing/transcribing a long video can be tedious. You can outsource it to a Virtual Assistant, maybe someone on Fivrr. A trick I’ve used is to play the video back and use an app like Dragon dictation. Then edit the text to clean it up.
