This chart, from Newswhip via Derek Thompson, has been doing the rounds, and causing a bit of debate:
The question: What on earth is Upworthy doing so right? How is it that Upworthy’s articles shared a good order of magnitude more often than anybody else’s?
Part of the answer is that Upworthy simply doesn’t publish that many articles overall — a couple of hundred a month, each one carefully and laboriously optimized, through extensive A/B testing, to be as socially infectious as possible. But that doesn’t fully explain how Upworthy’s articles can be so much more viral. For that, Upworthy needs the help — either on purpose or inadvertent — of Facebook.
Facebook is the monster in the publishing room: a traffic firehose which can be turned on or off at Mark Zuckerberg’s whim. Right now, it’s turned on, and while a lot of sites are feeling the love none is doing so more than Upworthy. (Except, maybe, ViralNova.) So, how does Facebook give Upworthy such a big boost?
Let’s start with the basic mathematics of virality. Start with an article, any article; let’s stipulate that it gets 1,000 pageviews, naturally, just by dint of being published on a certain website. Now, let’s say that 1% of that article’s readers decide to share it with their friends, and that each reader has 100 friends. That means 10 people sharing, and 1,000 new people seeing the link. How many of those people will click the link? Let’s say it’s 10%. Which means that the article gets a boost of 100 new pageviews. Those extra pageviews cause their own viral loop, which generates an extra 10 pageviews, and that’s where the cycle pretty much peters out. Thanks to sharing, the article has been viewed 110 times, over and above the original 1,000 pageviews.
This requires a formula. Call the basic strength of the website PP, for publisher power: that’s the number of pageviews you can expect to get when you publish an article on your website. You then multiply that by S, or shareability: the likelihood that a reader will share your article on Facebook. That in turn gets multiplied by F, or the number of friends per reader, and then by C, which is the clickbaitiness of the headline.
The key number here is S·F·C, or shareability times friends times clickbaitiness. In our model, that’s 0.01 * 100 * 0.1 = 10%. If you increase any of those numbers — if you make people more likely to share your article, or more likely to click on the headline — then you’re going to increase the virality of the piece. For instance, if you double the proportion of people sharing the article and also double the probability that someone is going to click on the headline after seeing it, then S·F·C becomes 0.02 * 100 * 0.2 = 40%. If you start with 1,000 pageviews, then you’ll get another 400 viral views which in turn will generate another 160, and so on: your viral boost goes up from 110 views to 660 views.
You can see that a relatively small tweak to the variables in the S·F·C formula can make a very big difference to your total pageviews. Pretty soon you can double your initial pageviews, or treble them — and, then, when S·F·C exceeds 1, you achieve escape velocity: your article just keeps getting shared more and more and more. Getting S·F·C > 1, then, is the goal of all would-be viral content, and it’s by no means impossible: if 5% of an article’s readers share it, and those readers have 200 friends each, and 25% of people who see the headline click on it — well in that case, S·F·C is a whopping 2.5, or 250%.
At those levels, it almost doesn’t matter what PP is — how many pageviews you seed your article with before it goes viral. PP still matters, however — which is why so many viral sites have pop-up boxes which try to harvest your email address. It turns out that emailing lots of people with links to new content is a great way to start the ball rolling.
But there’s a fly in the ointment, here — something which makes achieving escape velocity much more difficult. Let’s call it FBT, for Facebook Throttle. If you share an article on Facebook, and you have 100 friends on Facebook, that does not mean that your 100 friends are all going to see that article in their newsfeed. Far from it. After you click “share”, Facebook then decides whether the article you just shared is going to appear in your friends’ feeds or not. (This is a very big difference between Facebook and Twitter, which shows you everything your friends are sharing.)
