I have a new client who runs an internet radio station. His site has hundreds of previously recorded shows and I would like to optimize the audio files for SEO as much as possible.
I've consider doing the following:
- Add schema.org markup.
- Add ID3 tags to the audio files themselves.
- Name the files descriptively.
The question that I have is, what are other ways to optimize audio files for SEO?
Note: I've consider transcribing each radio episode so search engines can see the transcripts but that would be either too time consuming or cost too much to hire a person/company to do it.
