Google seems to be rolling out podcast-based knowledge panels in Google Search. When you search for your favorite podcast, you might see a new knowledge panel show up in the search results.

Why we care. If you or your clients run a podcast, check to see if you are noticing this new knowledge panel in the Google search results. If not, it might be related to the RSS feed your podcast is produced on. Sadly, there is no official documentation how your podcast can show as a knowledge panel.
