Every single advertising company is exploiting every single side channel that they can. This should not surprise you.
Sure. And in this case, they're showing me irrelevant ads, shopping results I can't use and more. It's not surprising me, it's baffling me because it's just stupid to do this .
I recently bought a brand new pair of golf shoes from a physical store. I did not even search for them or look at any golf shoes online. The next day, I got Google ads served for the same brand of shoes I bought... Coincidence? Seemed very creepy. I know they sometimes do "re-tageting", but in this case I am sure I didn't look at any stores online. Only the fact that I physically visited a store with my tracking devi…
This [1] shows the attributes Facebook Custom Audiences allows match on, and it includes email, phone, first/last name, address, dob, and age. So if any of those were shared with the store, they can upload them to FB (and very similar to Google) to show you ads.

In a http request/response, mac address would be meta data. ARP is not a thing there. That would be an example of data snaffling.
Do you have any info on this? AFAIK, MAC is only distributed in datalink layer around local connections. I tried some quick packet sniffing browsing Google and did not see my MAC transmitted—as I’d expect (bc like you said, ARP not thing at this layer) also research on “MAC included in http metadata” turns up no results… If you have any more info on this I’d love to learn more—as I’m puzzled to know why this would ha…
Not you IP address but your router/access point's MAC address and been doing it for many years. For example, I receive quite a few devices for reviews, and I mostly give things away after using those. Many years ago, I gave a friend in another city a router. For a few weeks his computer and other devices reported his location as being my city instead of his. It took a couple of weeks for Google services to catch up.…
How do they get mac address from HTTP requests?
I believe they also track and log other Wifi networks that you arnt even connected to.
I'm sure they gather all sort of other metrics from any sensors and signals they can access.
Google changes the UI language in its first party apps based on IP, which is a much bigger deal than advertisers chosing to send Spanish ads to people who spend time in Spanish language countries.
I've always wondered what I'm supposed to do when on holiday in a country with a different script that I can't make heads or tails of. I'll have to practice my japanese or amharic then I guess?
The other extreme is DDG which will try to find English results for a query that very clearly uses Dutch words, matching pages that don't have those words on them rather than bringing up the Dutch page that contains all of the keywords.
After a while, Google would associate the IP address of the local side of the tunnel with the location of the remote side of the tunnel.
I assume this is from Android devices connecting to the network on the remote side, being geolocated by Google Play Services, and Google tying this location with the IP address.

It is way before HTTP even happens. This data is collected while you are driving around, walking down the street, etc.
