Is the Itunes Podcast database exposed to Google search engines?
It is, but the previous poster is correct and it isn’t the best resource. A good way to get an indication of whether you own podcast is getting any notice is to set up a Google Alerts account. For my own show, The BeanCast, I have a range of alerts and periodically will get notices that show an iTunes link string. However, the content itself is not optimized nor accessible to the engines, so all Google is really seeing are the link pointers that launch iTunes. The long and the short is that there is no way to manipulate or enhance exposure on iTunes, whether internally or externally. Their choices of who to feature and promote are based solely on internal preferences and proprietary traffic algorithms that they do not share publicly. Because of this, the Google rank for any link they generate is essentially meaningless since it is tied to nothing but the file name. All we know about it is that apparently subscription numbers matter, you can game that system by clicking on the subscript
