I've seen some really cool ads that were right on target - like the time
I played a James May video on YouTube and the ad that popped up
was for an electron microscope. I couldn't begin to afford the one
the advertiser wanted me to buy, but I actually did poke around eBay
to see if there were any old ones out there I might be able to afford.
I've hit paydirt many times when Amazon and others pointed out
"people who bought this also bought..."
That's the way it's supposed to work.
Then there are the way off base ads. I wonder if they are genuinely being
blasted out to everybody, or if I fall off too many if-then-elses for anything
more relevant to come up. These ads are invariably back-of-the-comics
and/or cable tv infomercial quality, like the perennial "weird trick for belly fat" ads.
I suppose I get those because Facebook et al know I'm a woman.
That's the deal we made, I suppose. A quasi-free internet supported by
advertising. And, like all things, 99% of internet advertising is crap.
