In the era of click-bait and algorithms

LIKE MANY THINGS at Facebook, the ads auction is a version of something Google built first. As on Google, Facebook has a piece of ad real estate that it’s auctioning off, and potential advertisers submit a piece of ad creative, a targeting spec for their ideal user, and a bid for what they’re willing to pay to obtain a desired response (such as a click, a like, or a comment). Rather than simply reward that ad position to the highest bidder, though, Facebook uses a complex model that considers both the dollar value of each bid as well as how good a piece of clickbait (or view-bait, or comment-bait) the corresponding ad is. If Facebook’s model thinks your ad is 10 times more likely to engage a user than another company’s ad, then your effective bid at auction is considered 10 times higher than a company willing to pay the same dollar amount.

A canny marketer with really engaging (or outraging) content can goose their effective purchasing power at the ads auction, piggybacking on Facebook’s estimation of their clickbaitiness to win many more auctions (for the same or less money) than an unengaging competitor. That’s why, if you’ve noticed a News Feed ad that’s pulling out all the stops (via provocative stock photography or other gimcrackery) to get you to click on it, it’s partly because the advertiser is aiming to pump up their engagement levels and increase their exposure, all without paying any more money.

In other words, it can cost me more for the same advertising space as you because I'm not as creative. Do I want that? Do you?
During the run-up to the election, the Trump and Clinton campaigns bid ruthlessly for the same online real estate in front of the same swing-state voters. But because Trump used provocative content to stoke social media buzz, and he was better able to drive likes, comments, and shares than Clinton, his bids received a boost from Facebook’s click model, effectively winning him more media for less money.
So, it pays to be a flaming dickhead.  At least on Facebook. And "negative ad campaigns" really do work.
The above auction analysis is even more true for News Feed, which is only based on engagement, with every user mired in a self-reinforcing loop of engagement, followed by optimized content, followed by more revealing engagement, then more content, ad infinitum. The candidate who can trigger that feedback loop ultimately wins. The Like button is our new ballot box, and democracy has been transformed into an algorithmic popularity contest.
I've just lately realized (been educated) that every time I "like" something on Facebook or Twitter, I'm narrowing what I see in the future. It's blithely called targeting and is supposed to be for marketing purposes. But it's also reinforcing what I think by virtue of feeding me information that coincides with what I like. I don't get the opposing view. And neither do you. Unless you specifically seek it out. No wonder we're becoming more and more polarized.

As for actual merchandise advertising, it apprently works a little differently.
What advertisers want to do is find the person who left a product unpurchased in an online shopping cart, just used a loyalty card to buy diapers at Safeway, or registered as a Republican voter in Stark County, Ohio (a swing county in a swing state).

Custom Audiences lets them do that. It’s the tunnel beneath the data wall that allows the outside world into Facebook’s well-protected garden, and it’s like that by design.

Browsed for shoes and then saw them on Facebook? You’re in a Custom Audience.

Registered for an email newsletter or used your email as login somewhere? You’re in a Custom Audience.

Ordered something to a postal address known to merchants and marketers? You’re definitely in a Custom Audience.
The really fun one is when I've just bought something online and then I start receiving ads for the very thing I just bought. I don't need it now.  I'm not going to click on the picture to look at it.  I have it.  Somebody really needs to fix that algorithm.
Here’s how it works in practice:

A campaign manager takes a list of emails or other personal data for people they think will be susceptible to a certain type of messaging (e.g. people in Florida who donated money to Trump For America). They upload that spreadsheet to Facebook via the Ads Manager tool, and Facebook scours its user data, looks for users who match the uploaded spreadsheet, and turns the matches into an “Audience,” which is really just a set of Facebook users.

[...]

In the language of database people, there’s now a “join” between the Facebook user ID (that’s you) and this outside third-party who knows what you bought, browsed, or who you voted for (probably). That join is permanent, irrevocable, and will follow you to every screen where you’ve used Facebook.
One thing I always avoid - and by this point, I don't know what difference it could possibly make - probably none, but I do it anyway - is signing in to any other account using Facebook, or Google, or whatever options it gives me. Theoretically, that should keep Facebook from at least tying in to that account, but they probably have plenty of other ways.  I'm the internet advertising equivalent of people who think they're safer traveling by air if they take their shoes off to get through security.  Not true, but if it makes you feel better, eh?
The above is pretty rudimentary data plumbing. But only when you’ve built a Custom Audience can you build Lookalike Audiences— the most unknown, poorly understood, and yet powerful weapon in the Facebook ads arsenal.

With a mere mouse click from our hypothetical campaign manager, Facebook now searches the friends of everyone in the Custom Audience, trying to find everyone who (wait for it) “looks like” you. Using a witches’ brew of mutual engagement—probably including some mix of shared page Likes, interacting with similar News Feed or Ads content, a score used to measure your social proximity to friends—the Custom Audience is expanded to a bigger set of like-minded people. Lookalikes.
This bit becomes really obvious when Facebook puts "people you may know" into your feed. It really should say "people who may know someone you know" or "people who happen to like something you also like, so maybe you'd like to know each other."
One of the ways the Trump campaign leveraged Lookalike Audiences was through its voter suppression campaigns among likely Clinton voters. They seeded the Audiences assembly line with content about Clinton that was engaging but dispiriting. This is one of the ways that Trump won the election, by the very tools that were originally built to help companies like Bed Bath & Beyond sell you towels.

[...]

The above isn’t mere informed speculation, the Trump campaign admitted to its wide use of both Custom and Lookalike audiences. There seems to be little public coverage of whether the Clinton campaign used Facebook Ads extensively, but there’s no reason to think her campaign did not exploit the same tools.

[...]

If we’re going to reorient our society around Internet echo chambers, with Facebook and Twitter serving as our new Athenian agora, then we as citizens should understand how that forum gets paid for. Rarely will the owners of that now-privatized space deign to explain how they’re keeping the lights on. Plotting Russians make for a good story, and external enemies frequently serve an internal purpose, but the trail of blame often leads much closer to home.
...but hey, do what you want...you will anyway.
