> The more they know about you, the more relevant your ads will be and the more likely someone seeing your ad will be to buy How much ACTUAL evidence is there

> The more they know about you, the more relevant your ads will be and the more likely someone seeing your ad will be to buy How much ACTUAL evidence is there for this? Take Amazon for instance... they know everything I have bought from them ever and employ some mega-smart people but the number of times I buy something and they then recommend either absolute shite or the same damn thing is not an insignificant number. Another thing is if I am an advertiser and FB says "your ad was seen by 20 million people", how can I dispute this? It's a closed system. I am sorry... but from my comfy armchair position I'm calling shenanigans on mass-data collection in advertising being able to move the profitability needle in a measurable way. Edit: Added a bit more stuff

I worked in ads. You individually is not what makes advertising useful or lucrative. Aggregate numbers do. How many people see ads on tv, and buy the thing they saw right away? You guessed it, it is probably less than a percent. There are so many impressions in the world, from billons of users. You cannot expect each of them to do meaningful conversions. On a super off the cuff calculation, assume each user see 100 ads a day, 2b users makes it 200b impressions. If each user generously converts once a day, that is 1%. If they convert every other day, it is 0.5% per impression. I particularly left clicks out went straight to conversions. Usual flow goes like this: query, matched query, impression, click, conversion... The funnel is super large and drop offs are huge.

    It works (Has a positive RoI) up to a particular spend/impression, and doesn't work after a particular spend/impression. The purpose of all the data collection/targeted advertising/remarketing, is to increase the efficiency of these ads, and to increase the threshold when it goes from 'works' to 'doesn't work'. To put it another way - I can't think of many businesses where showing ads for 1 cent / 1000 impressions would not be worth it. I can't think of many businesses where showing ads for $1000 / 1000 impressions would be worth it. Depending on the business, there's some inflection point between those two numbers. More targeted advertising makes the implicit promise that the inflection point for <your particular business> is higher, then in an untargeted advertising platform.

    What incentives would the ad industry have to defend a practice that isn't popular and doesn't work?

      What incentives are there to claim that their company can sell your company access to their secret sauce which greatly improves some metric which is notoriously hard to measure?
      - SpicyLemonZest 7y ago
        It's very easy to measure the success of online advertising campaigns, because you can directly measure how many people your ads are reaching and which of those people end up buying your stuff. Even if it weren't, I still don't see the incentive. If you don't think that it matters what your secret sauce actually is, why use mass data collection rather than something more popular?
        jddj 7y ago
        I was all geared up to play devil's advocate here, but any response I could formulate seemed to distill down to data being extremely powerful, and so undermined the thesis. Still though, if Facebook has solved the "50% of my ad spend works, I just don't know which 50%" issue for companies like Mercedes Benz and Coca Cola then that would be mighty impressive.
        bluGill 7y ago
        No it is not easy to measure. You can measure immediate success, but not delayed success. I just bought my first order for a product that I last saw advertised on facebook a couple years ago. At the time the product looked interesting but didn't fit my needs, but a couple years latter and I remembered them. Since I've moved and used firefox directly to access their website it will be very hard to put my order with the ad (they have probably closed the books on the original ad where I'm marked as a click but no buy)

    Are ad-hating HN users ever going to say that ads might work sometimes, instead of relying on random anecdotes and 0 data or facts from an extremely small and biased sub-population who is never the target of advertising campaigns anyway? Or are you really arguing that >$500B businesses like Google and FB are complete fraud?
    - meowface 7y ago
      I hate ads, but I agree with you. I hate them because they work. Or at least, all this money wouldn't be flowing into the industry if it really wasn't working. Maybe FB is fraudulent due to the accusations in the article (inflating numbers to advertisers), I don't know; that's unrelated to the issue of giant, innovative tech companies basing their entire business models on advertising things to their non-paying users, and visitors, and also anyone else who ever visits pretty much any other website on the Internet. Advertising isn't fraud. Neither is data collection. It's just unfortunate. I wouldn't even be surprised if many Google and Facebook employees agree it's unfortunate. They're probably thinking: what else exactly can we do to sustain all these non-paying users? It's really not even the data collection that bothers me so much as the fact that it's being used for such a... dumb purpose, I guess. The best minds of our generation are dedicating their life's work and all of their brainpower to thinking about how to get people to see or click more advertisements. What a waste.

      I didn't claim that ads don't work... far from it: I've seen how easily people are persuaded to part with money so I believe ads DO work! What I have issues with is using masses of data to persuade someone to buy something having any more significant ability to make them part with their cash than doing it contextually. I realise I said "measureable effect" and I kind of meant that in my original statement but I also mean measurable enough that my privacy is traded for an extra fraction of a percent. By way of example, lets say a contextual banner ad at the top of an article for the new Hyundai i30 Fastback N (I just bought one of those :) with a discount code to buy one might persuade 10% of people to click and 10% of them to buy. (Illustrative figures, don't throw your back out over their accuracy) If adtech companies hoover up data across the web about my buying habits, browsing habits, sexual habits etc. can they legitimately say they can make a measurably larger percentage of people buy that car (or handbag, shoes whatever)? And if so, what kind of numbers? Is it 10.1%? 30%? And is that trade-off worth me allowing them to do that? That's my issue with ad tech.

I think you are missing the point here and thinking too much about pay per impression. Professional ad buyers don't measure their ad effectiveness in "people reached". That is for chumps who want to be ripped off, and large companies that have too much to burn on their marketing departments. The people who use ads effectively are buying pay per click and measuring the real conversions to measure effectiveness. Bots don't buy the products after they click through, but the real clicks often do. (For some categories you can get as high as 10% conversion rate to a real sale from real clicks that you buy because ad targeting on platforms like Facebook and Amazon is really, really good. If your ad is good and your product is good then the ad targeting will get your ad in front of the right people a lot of the time.) If you are smart you don't pay for impressions, you pay for clicks and conversions, and you measure how many of those clicks convert into sales to make sure you are coming out net positive. Sure there are always going to be some fake clicks but there are still enough real clicks that convert to make it worth it. A bit of click fraud is just the cost of doing business. Lets say I'm selling a product that has a 20% profit margin. I might be willing to pay up to 10% of my profit margin on ads if the increased number of real conversions that result will more than double my sales, allowing me to make more money overall than I would have otherwise. There are definitely a lot of people out there who are foolishly wasting money on buying impressions, but there are also tons of people making ludicrous amounts of money from well targeted ads that convert into increased sales of their product

  You are over-simplifying. Almost all of the metrics Facebook will feed you when you setup an account are on a view-through attribution basis. Yes, there will be some clicks, but if you attribute revenue from Facebook by clicks only, it will look terrible. This is an old problem for anyone that has spent time with display ad platforms. So, you install a facebook pixel on your checkout, and if the person making a purchase saw your ad on Facebook, Facebook's reporting console will take credit for that. Thats view-through attribution and it highly overstates the credit Facebook should receive for making the sale, but there's not much you can do to measure it otherwise. So what do you do? The answer is, you setup a holdout test. Facebook has a black-box solution for helping with this, but it is a huge conflict of interest to let Facebook handle your test. The thing to do then is set up the test on your own platform. That is a massive undertaking, and any business that doesn't have a significantly sized engineering and analytic team doesn't stand a chance. So yea, people look at things like reach, and view through conversions, and it would be very hard not too or they might not have the means to do something more sophisticated. Fake accounts undeniably puff of numbers for these people, and they should be taken to court for not giving a shit about that fact.

I'm working with comscore right now (an aggregator of stats for advertisers) and can confirm it's all a house of cards. there's no quality controls or oversight into what's reported.
ci5er 7y ago
In my companies and for my clients, I track up-tick in sales for each campaign on each platform. Sometimes the problem is conversion (that's on me/us), and sometimes bad targeting or whatever. If FB isn't one of the lowest channels (platforms) for CAC that is greatly exceeded by LTV (or even <3 mo breakeven), then it isn't a channel you use for that product!
kickopotomus 7y ago
I don't think Amazon is a good comparison here. Yes, they have a lot of data on the things that you buy but at the core, Amazon is a logistics company. Advertising is not their profit center. Facebook and Google are both advertising companies. That is how they make money so naturally that is also where a lot of their R&D spend goes.
