I’ve done 9 podcast appearances this year for my own consulting brand. Most shows have a show notes page, and 7 of them linked to my site, mostly dofollow.
The links are from small but real sites, DR 20-45. Time cost was roughly 3 hours per episode including prep and outreach to hosts.
From a pure link point of view it seems decent, but I can’t tell if it moved anything. Has anyone done this at bigger scale and seen rankings respond?
