The ad industry is just so damn broken that it's ripe for a huge disruption. The whole hypothesis of Google- that people will want to see ads centered on what they are searching for- seems to be erroneous. But it's been taken as gospel for what- a dozen years?- that everybody has piled on to the idea that we can know what people want to buy based on the type of information they seek. I think that except in explicit cases- searching for 'umbrellas that can withstand high winds' for instance- it's not true.
As I've said before here, when I'm ready to buy I'm searching Amazon, not Google.
Can you be certain that this is true? Perhaps you didn't click through (I don't either), but what if your unconscious mind saw an ad that you did not register consciously.
