       Ask HN: I bought Voltaren at the chemist, now Google shows me ads
       for it. Why?
        
       How does google know I bought Voltaren?  Is my bank purchase
       history shared with google somehow?  I guess it could just be
       coincidence?

         | Old school internet ad tech worked around what you are trying

         | AdSense and well before acquiring DoubleClick.
         | 
         | The way it worked at [former employer] was, we had a lot of
         | digital properties. Every digital property collected analytics
         | on all visitors. All that analytics got post-processed and
         | cross-referenced until we could form a "profile" on every
         | visitor. Because you leave a teeny tiny trail of information
         | everywhere you go, we cobble it all together until we know who
         | you are on each site. The probability just gets higher as we
         | collect more data. And we'd collect data from everywhere -
         | e-mail marketing campaigns, ad traffic on partner sites, user
         | profile data, web surfing habits, and buying access to
         | privately maintained databases.
         | 
         | Even if everyone wore a mask and black clothes everywhere they
         | went, surveillance cameras still capture height, gait,
         | mannerisms. Watch long enough and you know "Gait #24434
         | mannerisms #593483 height #933 goes in/out of this residence at
         | these specific times, goes to this supermarket, goes to this
         | nail salon, sometimes goes to a house somebody else seems to
         | live in".
         | 
         | Maybe it's multiple people with the same gait, mannerisms,
         | height - but in the same neighborhood? In any case, it doesn't
         | matter if they are all different people as long as they behave
         | the same way; we market to them the same. Your entire life is
         | just a string of digits in a marketing-recommender algorithm.

         | 2. You likely searched online for these at some site and

         | 
         | The only thing that will get rid of this is to ban/regulate

       | There could be many ways but it doesn't really matter that much
       | which of them was used this time. The real solution is twofold:
       | 
       | - Block ads. All ads. No advertising allowed, ban it, rigorously.
       | 
       | - To do that effectively on a "main stream" mobile device (i.e.
       | not a Pinephone or Librem running some form of Linux with a
       | mobile shell) you need an Android-capable device on which you
       | install an AOSP-derived distribution (LineageOS being the most
       | well-known and -supported). Do not install Google apps ("gapps").
       | Install a system-wide ad blocker, there are several options here
       | ranging from a simple hosts-based solution (efficient but less
       | effective) to vpn/proxy based solutions (effective but less
       | efficient), I use the former. Use Firefox with uBlock Origin,
       | sync your filter list with the one on your PCs for a quick start.
       | 
       | Also, pay with cash if you can to deny the beast some more data.
       | 
       | If you use "free" wifi make sure to only use it to connect to
       | your VPN server, don't use it directly other than to check
       | whether your flight or train is in time etc.
       | 
       | Don't feed the beasts, starve them. It doesn't matter whether
       | that beast goes by the name of Google or Apple or Amazon or
       | anything else, just don't feed them.
       | 
       | Don't use the Google search engine directly, use it through a
       | meta-search engine like Searx. Don't use "stock" Android, stock
       | iOS, stock Windows as they come on those shiny new gadgets, at
       | the least find out how to disable the myriad of "telemetry" these
       | things come with. Replace stock Android with an AOSP-derived
       | distribution - unfortunately there is no similar option for Apple
       | devices. If you're mostly using PC-type devices as glorified web
       | terminals you're better off doing that using a free Linux
       | distribution (Debian is a good choice, free of commercial
       | interests, no tracking included), no need for Windows or MacOS
       | here.
       | 
       | Don't even thing about using Siri, Google Assistant, Alexa, Echo
       | or whatever voice-related gadgetry they come up with tomorrow,
       | that stuff is straight out of an Orwellian nightmare. Any voice
       | processing should be done locally on the device, it should work
       | without any internet connection. If it needs an internet
       | connection to work you just don't use it. This can be generalised
       | to other services as well, there has to be a clear reason for the
       | service to need an internet connection or you simply deny it such
       | - this is possible on the mention AOSP-derived distributions by
       | using a firewall which blocks outgoing connections, iOS users are
       | sadly out of luck in this respect unless they are willing to
       | permanently fight Apple for control over their devices.
       | 
       | If you can, run your own services - mail, chat, web, video, media
       | etc. This takes a bit of effort but it gives a lot of freedom in
       | return.

       | Do you know companies actually send data to Google (and Facebook)

       | 
       | Its common and help companies target clients with ads on the
       | internet in general (YouTube, sites, etc).
       | 
       | It works like that:
       | 
       | - The Chemist wants to sell things online or physically.
       | 
       | - They pay google for ads for their products on sites related to
       | its business lines or keywords about its niche.
       | 
       | Google then show their ads for people in general, people
       | interested on those subjects or to people visiting sites about
       | those subjects.
       | 
       | Interest is determined by search history and navigation (every
       | google ad in a site (chemist or not) help google know you were
       | there).
       | 
       | Then the chemist want to target past customers with more specific
       | ads (like reminding people of items in theirs carts):
       | 
       | - They send google ads information about clients and past
       | physical or online purchases / interactions.
       | 
       | Google then match the user with its own database and connect the
       | sent data with its own data.
       | 
       | - Now the Chemist benefits from the google (because google can
       | find you online)
       | 
       | - Now other google clients benefit from this data (because now
       | your google hidden profile is more accurate about your interests
       | and habits)
       | 
       | - Now Google benefits from that because it can use the purchase
       | data to hone its models about ad-to-spend.
       | 
       | The chemist also want to pay google a fraction of the purchases
       | if the client saw an ad.
       | 
       | - Google uses information sent in realtime by the Chemist and
       | other companies, model this data and determine which people,
       | sites and subjects have a bigger probability to turn an Ad into a
       | sell.
       | 
       | I have myself done that in the past and Facebook was quite
       | accurate at turning ads into course subscriptions.

             | 
             | The third option is LineageOS (was originally CyanogenMod

             | because the bootloader is left unlocked (which may or may
             | not be relevant depending on your threat model), it is the
             | least secure of the three.
             | 
             | Both GrapheneOS and CalyxOS have very user-friendly
             | installation methods, but exist primarily for the Pixel
             | line of devices. LineageOS has the most involved
             | installation process, but it's available for the widest
             | variety of Android devices.
             | 
             | I've installed all three ROMs on several different devices.
             | For the average person, CalyxOS will probably be the best

       | Lots of ways this data flow could happen, at least in the US.
       | Happy to go through specific details I have seen if you want to
       | share more about this, but two high level points
       | 
       | 1. Remember that when you purchase something, the data about the
       | purchase is BOTH yours AND the entity from whom you made the
       | purchase. Most of those entities have data sharing agreements of
       | various kinds for all sorts of legitimate business reasons
       | 
       | 2. It isn't _google_ who knows about the purchase, and even the
       | advertiser doesn 't "know" _you_ made a purchase. Advertising is
       | zillions of two sided marketplaces, with an enormous ecosystem of
       | data packagers and conveyers and linkers, with lots of concern
       | about recency and freshness of data. Your purchase landed some
       | key about you in a bucket that was mixed and repackaged with many
       | other keys that the advertiser knows as  "keys recently
       | interested in Voltaren." Some of those keys are related to people
       | who bought it, or who searched for it, or more indirectly who
       | lingered while reading a page with an ad for it...and in most
       | cases are very short lived. So give it a few weeks and many of
       | those buckets of keys will have been completely remade.
