The ads I see on yahoo and yahoo mail I assume are targeted at some of the surfing I do… I say this because when I was researching buying music for my son’s piano lessons – I started seeing music ads. When my husband and I were dreaming about buying a boat and looking at boat websites a lot – I started seeing marina ads and yacht ads… And when I’ve been researching airfare for vacations, I start seeing lots of resort ads…
I’m not speculating why you’re getting bouncy girls with suggestive faces… Just saying that that the ads I see, tend to correlate to recent browsing.
