I doubt it is even a ban. It definitely isn't a shadowban.

A ban is when you are preventing from participating in something. Google is a service that indexes the internet and provides references to relevant information. Website providers aren't the users here, web searchers are. I guess you could argue that the site was 'banned' from search results, but I doubt that the author would care enough to search 100 pages of search results to see if they were still there, they just care that they aren't a first page hit.

A shadowban is when a participant has been banned, but has no idea it has happened. This came about on certain link aggregation/social media sites as a solution to people being banned and creating new accounts and resuming their behavior.
