The is something that someone really should study, along with "Who are buying ad space". My theory is that the quality, for a lack of a better term, of advertisers are going down.
Let's say I need a new vacuum cleaner and do a Google search. I get eight sponsored products. Three a links to stores I'd expect, the rest are fairly unknown sites, mostly the "We sell everything" stores. Weirdly enough also only one of them are via Google ads directly, the rest are via PriceToro and Channable, both of which I don't know.
My personal theory is that Google is still making pretty good money, but from increasingly questionable ads.
