If I put an HTML5 video player on a web page and it has an associated caption file (WebVTT) using the
<track> tag inside the
<video> tag (heres a link in case you are wondering what I am talking about), will it affect my search results in a positive way?
I am trying to avoid putting the transcript of the video on the page inside a hidden element (I am not an SEO expert but I have heard that hiding text with
visibility:hidden is not a good idea).
TL;DR: Will search engines index the contents of a video caption file?
