The online ad business generally mystifies me. While an awful lot of the internet, especially the surveillance advertising part, looks to be the greatest misallocation of engineering (and other) talent in the history of the world, ya gotta ask about the efficacy. The only reasonably accurate targeting I've ever run into is the occasional ad for something I just browsed on Amazon. I've never clicked on an internet ad.…
Generally yes but Instagram ads are somehow amazingly well-targeted towards me. Literally every ad I say to myself "wow, that is actually something I would consider buying" and in certain instances, I have. Outside of Instagram it is exceedingly rare that I would purchase something based on an ad.
I've seen things go from saying things in a conversation to targeted advert on Twitter, for example, in under 1hr routinely (although not always). Many of my peers have reported the same. While I've reproduced this on multiple devices (Android + iPhone) over many tests, I've been unable to isolate the app(s) doing this and how it works.
It's baffling how it's done and at scale, but somehow a few organizations seem to have extremely advanced adtech in production.
