Transcribe Text Content Into Audio (Or Vice Versa)

Offer a blogger an audio version of their post…or a text version of their podcast or video.

Word of warning: make sure you don’t trade this service in exchange for a backlink (this goes against Google’s webmaster guidelines). Just send them the text or audio. And leave the linking decision up to them.

Plus, even if you don’t get a link, you’ve done someone a solid. And that can lead to a long-term relationship down the road.
