Yeah I think Google and other advertisers are great at predicting what people will buy and then shows them ads for it. That’s different than showing a person an ad and changing their behavior, but to advertisers they can’t know unless they experiment.
> Yeah I think Google and other advertisers are great at predicting what people will buy and then shows them ads for it. Seems to be entirely subjective. I bought a new blade for a bread cutting machine on amazon, the last one lasted ~25 years. My current recommendations: blades for bread cutting machines. I also checked some Christmas decorations on Amazon, but didn't buy any. So next to the blades I get Christmas d…
While that's definitely true (I get ads from Amazon for stuff I've already purchased all the time too), in that case Amazon is leveraging their own marketing channels to support their own business -- which has, effectively, zero marginal cost to them.
However, when advertisers buy space from Google or FB, that's not the case. There is a definite external cost to such ad buys.
As such, being able to identify the "value" of such expenditures is (or can/should be) important to the advertisers.
That said, much of advertising is based upon the idea of "top-of-mind awareness."[0]
The idea being that if you are considering a purchase, the brand that comes to mind without prompting when considering that purchase will be preferred over brands of which you aren't immediately aware.
Purchase decisions made on a whim or without any research are usually those which are low cost. Which is why companies like P&G, Coca Cola and like companies focus on "top-of-mind awareness."
If you're going to buy a washing machine or a riding lawn mower, you're much more likely to do research than if you're going to buy a soft drink or a bag of chips.
That said, the same "top-of-mind awareness" can be helpful even for big ticket items, as those brands may well be the first ones about which research may be done.
Identifying how such advertising may impact purchase behavior is a complex topic, and unless you can quantify specific ad-views to actual purchases, doing so is generally speculative and is the subject of a great deal of quantitative market research[1].
