Its the times we live in
One of the larger AM stations serving the Los Angeles market (KFI) seems to live off advertising for attornies (mostly accident, some timeshare and tax), mortgate refiance and dubious investments. A few months ago there was also a sprinkling of car dealer ads but car sales have been in free fall so even that's stopped.
Its a good bet that the online market follows the radio market. I just assume that all advertisements are scams and I don't bother trying to use Google to look anything up.
(Incidentally, many people on the Left Coast assume that anything out of Florida is either a weird conspriacy theory or a scam.)
