Adblocker stops you from seeing the ad but not from google deanonymizing and linking your transactions to your search. Also lots of websites these days require you to disable adblockers to function.

I don't use those websites.

It’s probably a coincidence or just the worst advertisers on the planet. Why would I show an ad to someone who literally just bought my thing?

It's pretty common. I once bought a fan online and had ads for that same fan follow me around for weeks. I believe they're called "retargeting" ads.

Retargeting is generally done after you have shown interest in a product, but haven't converted yet. "Conversions" are always excluded if possible. It makes no sense to retarget a recent buyer.

I agree it doesn't make any sense, and I would prefer to live in a world where ads were served as you described.

It might be that you are just noticing the ads now that you bought the product. I read about similar observations recently. Might be a cousin of frequency illusion https://en.wikipedia.org/wiki/Frequency_illusion?wprov=sfti1

It's been a few times now where I've talked with my wife about some new product (physically, in the room) and she starts seeing ads about it. I thought that was the explanation too, but it's happened too many times for comfort. I know my devices are (probably) not listening, but I can't explain it either. Neither of us searched for the product or saw it online or anything, we just discussed something and got ads abou…

Not thinking this is happening either. But just to speculate on a fictitious scenario..

Given a shady company, maybe even outright involved in illegal practices, where employees employ any surveillance tech they can lay their hands on. All in order to collect as much personal information as possible, from as many people as possible. As such, they won't shy away from breaking & listening in and do subsequent speech-to-text information gathering (e.g. via some Ad-obtained Windows malware, or a malicious mobile app).

They trade the collected info on the data markets, selling to anyone who'd pay. Wouldn't it be likely that this data then indirectly ends up at Google, so they can indeed target - in this case Voltaren - ads to you?

Also: If any illegally obtained information enters the data markets.. won't it be 'whitewashed' automatically as it is trading hands?

Sure, but I don't think they're listening from a technical standpoint, because the battery consumption is much less than an active network adapter would consume.

They could always either compress the audio or do a speech to text (looking for keywords rather than caring about getting the whole context correct), and batch upload the results on an interval (like when checking for email or app/system updates).
