A couple of quick thoughts. First Google results are heavily customized on some queries based on your own interest, history, location, etc. So that exact makeup of results might be different for different users.Right now, if you Google “KNX-FM”, 11 results show up on the first page. Seven of them, including the top result, are for the two tribute streamers.
Secondly, I would imagine that Audacy has SEO (search engine optimization) people on staff or at least decent consultants that know how to get more Google Juice than amateur-hour station tribute sites (no disrespect intended). The real KNX-FM in the internet era just began, so expect the Audacy station to move up quickly and overwhelm the others, with or without any C&Ds.
