Multiple people have reported subtitle changes in their Knowledge Panel. Bill Slawski’s changed from “Consultant” to “Search Engine Technology” (Shurely Shome Mishtake, that should technologist, but hey !)
And for Matt Artz, the subtitle has been ping-ponging from Musician to Podcaster, back to Musician and now (it seems permanently) back to Podcaster.
This change for Matt could possibly be related to the massive Podcast Knowledge Panel update from a few weeks ago.
I hope to get some data from the Kalicube Pro dataset to see if this is is widespread. Stay tuned !
