  Please sign in to see what

  you.
Uh, actually, that's what I tell the internet about myself, for the most part.

It doesn't really impress me when I approach the internet and introduce myself by name. Of course the internet is going to remember me, if I permit my cookies and request parameters and IP address linger.

Much more interesting is when the internet makes my identity without my having volunteered anything.

Oh well.

I tried it a couple years ago with Google and once targeted ads were off, I would get many ads about gay dating sites. Once I turned targeted ads on again, these ads disappeared.

I had a similar experience, but it was single women, and there was no way to ask Google to stop showing me those types of ads. At the very least allow me to block adult advertisements. Maybe it's on purpose...

With me it is retirement planning... I am in that age range. I've just taken to either switching javascript off or using one of those hosts files that blocks most stuff.

You're underestimating how hard it would be to build such an engine. Google and Facebook have sunk $billions into their knowledge graphs so far, and not made much of a dent.

Maybe. The current heuristic is "he has bought X so show him an ad for X", but would it be so difficult to flip that to "he has bought X so show him the next thing on the list of interests we know he has" or even just "anything but X". I strongly suspect noone is doing this because there is no point, they get paid the same regardless.

That's not the current heuristic; it's not nearly that simple.

Think about how you know if someone is interested in something. What does it mean to be interested? How does that translate into a sale?

A person just bought a vacuum cleaner. Does that mean they are interested in vacuum cleaners? Are vacuum cleaners things that people get interested in? Do people who are interested in vacuum cleaners buy more than people who are not interested in vacuum cleaners?

To us these answers are so obvious that it's humorous. To a computer, not so much.

There are many millions of interests, opinions, and things to buy--so count the combinations. We understand it all intuitively because we are adult humans with decades of experience in this society.

This is why search and ad companies hire so many AI researchers.

EDIT: to understand the financial incentives, see my other reply to you. In a PPC ecosystem it is better to match too greedily than to risk missing a customer ready to buy.

I tried turning off targeted Google ads on my phone, and got only the worst ads possible from then on. Like, 100% strobing "YOUR PHONE HAS 37 VIRUSES, CLICK HERE TO CLEAN". Eventually I had to turn it back because ad-supported apps are nearly unusable with strobing banners at the bottom, which I'm sure was Google's intent.

Have you considered paying for the apps you use, or using open source apps (such as from F-Droid) that don't include ads?

Only ever open in airplane mode!

Thanks for this link, reminded me to install noscript on my Android/Firefox install!

no script's not very useful anymore for desktop, you need something like uMatrix for the modern web

Ad companies make money based on clicks, not views. It's in their interest to make them interesting enough to click on.

I don't think that's true, because who is clicking on these ads for things they already own?

Another alternative is that perhaps people are clicking on ads for things they already own. I mean, let's say there's a 1/5000 chance that a random person is going to buy a SDXC card. You go ahead and buy one. After the purchase, statistically does your likelihood of buying another SDXC go up or down? For some people, they've fulfilled their SDXC quota, so now their likelihood is zero. For other people, they may be in the market for SD cards generally, so they will be more likely to make a second purchase than a random person. Or, after having bought one, they'll want to buy another one as a gift. Or they're looking to return the original and buy a cheaper one at a sale price. Just the fact that they have equipment that takes SDXC cards means they're more likely to buy another one than a random person.

Same thing with a pool filter even. If you live in an apartment, or if you're a minor, or you don't own a pool, your chances of buying a pool filter are extremely low. So the fact that you just bought a pool filter puts you in the narrow group of people who would potentially have need for another pool filter. Even though you just bought one, you're still more likely to be a customer than a random person. Hence, generally speaking, sending you ads for the same thing you just bought may be a rational choice for the advertiser.

An intelligent advertising engine would know the typical interval between two purchases of the same product, and start advertising similar products just before that interval has elapsed since the last purchase. Examples: pool filter: 12 months reptile UV lamp: 6 months gift-wrapping paper: 12 months oil filter, recycling box, 5 qt oil: 4 months 8-ct paper towel rolls: 2 months television: 4 years automobile: 10 years…

That's the intuition, but I wonder if there isn't a spike in near-term repurchase behavior that the algorithms are correctly exploiting? Ex: I bought a vacuum, but I'm unhappy with it. I bought a pool or oil filter, but it was the wrong one. I bought an X, but it was defective. I bought an 8-ct of paper towels because I run a cleaning service or property management company and use a lot of paper towels. I bought a pa…

In the cases you provide, though, it seems to me (and I am certainly no expert) that you wouldn't need to advertise the same item again. If I bought a vacuum that I'm unhappy with, showing me another ad for it (which is what Amazon does) is the wrong thing to do. Not only will I not buy the same machine again, but I will google and research the products- I will ignore ads unless they are offering me a discount on the one I decide on. Likewise for wrong-sized jeans or buying three more pair.

Here's my "completely not ergonomic but entirely satisfying if silent protest is your thing" solution:

- NoScript [0], First defence. Breaks 30% of sites, but you can selectively enable local scripts to ameliorate that.

- Self-Destructing Cookies [1], We all need cookies for logging in to things and etc..., but once we've closed the tab, we shouldn't have to keep those cookies with us. This means you have to log-in more often, but I prefer that. Prevents people from seeing your email/facebook/etc... when you're still logged in.

- uBlock Origin [2], You'll occasionally need to allow scripts you don't like because they're required for the proper presentation of the website. In those cases, you can depend on uBlock to get rid of awful trackers.

- HTTPSEverywhere [3], Because snoopers aren't always outside your network.

- DuckDuckGo as default search engine [4] and not-Google Chrome as your default browser, At the very least, you're not supporting the worst privacy offender on the net.

- Non-ad-supported/privacy-oriented service. In the paid category (recommended), I suggest mailbox.org, due to their track record and founding principles. In the free(-ish) category, ProtonMail.ch and tutanota.com.

- Clear Cookies/History on Browser Exit

- Forbid Third-Party Cookies

- And because I believe in magical faeries, DoNotTrack set to True

Many apps don't have paid versions, only ad-supported, and even more apps don't have open-source equivalents. I'm sure you're aware of this.

I use an iPhone, although I have used Android many years ago (purely because of open source convictions), and I didn't know this. God, it's awful. I try very hard to use only paid apps on iOS even if there are free apps because I don't want to support the data-mining industry (not that paid apps can't participate in it, but at least I hope it's less likely).

Most apps cost less than a coffee, and personally I get more value out of the apps I use than from a cup of overpriced coffee.
