We have a few title tags with a circular dot symbol, which is created by the code "•" Humans see a dot, but googlebot sees • Does this negatively impact our SEO, or is googlebot aware that **• == *** to human eyes

We're considering transcribing our videos. It's a significant enough expense that we have to be sure of the impact. 1. How much effect do the transcripts have on Youtube SEO rankings? 2. Should we also post the transcripts beneath the video, or is uploading them sufficient? If we didn't post the transcripts, we'd just write custom keyword rich text for each video. We could post both keyword text and transcript text, but that may be too wordy. Does anyone have experience on how much Youtube transcripts impact rankings? Thanks
