TikTok's secret sauce
This Tuesday, leaked documents hint at more than meets the eye at ByteDance, Ubisoft offers a mea culpa, and New York is rolling out new vaccine mandates.
Two sides of the same code
If the only thing you knew about TikTok came from the media, you’d think it was an evil empire built with things called “algorithms” that suck children’s brains out, turning precious teens into short-video-watching zombies. But according to
leaked to The New York Times, the app’s algorithms aren’t that much different from what other companies are doing — and have been doing — for years.
This secret document is what ByteDance calls “TikTok Algo 101,” written by engineers in Beijing to explain to nontechnical TikTok employees how the app makes algorithmic recommendations.
- The company’s “ultimate goal” is growing daily active users by increasing user retention rates and total time spent each time TikTok is opened.
- Each video is scored by the number of likes, comments and playtime. There’s even a handy formula for success, according to the document: Plike X Vlike + Pcomment X Vcomment + Eplaytime X Vplaytime + Pplay X Vplay.
But none of this is new. Retention, use time, number of likes and comments: These are the types of numbers every website or app analyzes to make informed business decisions. It’s the premise of Web 2.0.
- While this is standard social media practice, some would argue that what made TikTok unique is how successfully it combs through oceans of data and designs an algorithm that performs better than its competitors. We all know apps care about retention and time spent, but how should the stats be prioritized? Are 100 likes better than 10 comments?
In fact, another closely related app uses the same secret sauce. In January, a document titled “Guide to a Certain Video APP’s Recommendation (Algorithm)” was released on several Chinese platforms. While it intentionally obscured which app it’s referencing, there are plenty of hints that it’s about Douyin, TikTok’s Chinese version.
- For one, the Chinese document describes how it makes recommendations in the exact same formula and language (yes, word for word) as the document leaked to the Times. They also used the same challenge to the algorithm as a case study.
- And in a Q&A entry about competitors, the document mentioned three other major Chinese apps — Toutiao, Kuaishou and Weibo — that rely on recommendation algorithms, but not Douyin, the app that does it the best.
- The two apps appear similar but have some different features, which has always led people to suspect that they run the same under the hood. But nobody outside ByteDance has been able to prove it.
ByteDance insists that it has completely separated the operations behind TikTok and Douyin, at the request of the U.S. That way, users and governments outside China don’t have to worry that the Chinese government is looking at their data. But according to the similarities in these documents, ByteDance might not be telling the whole truth. At least not yet.
- In 2020, former president Trump waged a war against TikTok, accusing it of transferring American users’ data to China and threatening national security. But he never succeeded in forcing ByteDance to sell TikTok to an American company.
- What ByteDance did do, in that spirit, was announce that TikTok would become a standalone company , with headquarters in Singapore and its own CEO, Shou Zi Chew .
- But can ByteDance accomplish a clean separation between the two apps, TikTok and Douyin, when they had been designed and maintained by the same group of people for years? And when they seemingly share algorithms? There have been several reports, like this one by CNBC in June, that say TikTok is still influenced by employees on the Chinese side. The latest Times column is another example.
In November, ByteDance settled a class-action suit that said the company illegally gathered data from its users. ByteDance not enforcing the separation as the pressure from Trump has waned is a pretty strong reason for the U.S. government to come up with its own data regulation tools. Especially useful would be legislation that regulates how data is sold and transferred, sometimes outside U.S. borders, as people are worried about their data falling into the Chinese government’s hands.
China has already done this. It has enforced or proposed several legislations this year that heavily restrict the outbound flow of personal data, especially when they pertain to national security. It’s unclear whether Beijing has ulterior motives other than protecting users and national security. Totally possible: It has already helped Beijing hold DiDi back from listing in the U.S. But by acting quicker than the U.S., China is selling an example of data regulation, as Protocol’s Shen Lu wrote in August . Many Asian governments are writing their own data protection laws now, and they may end up copying from China’s playbook if no other country steps up and figures out a way to do this effectively.

How to leverage ‘the network effect’
It’s hard to break into the tech world as a startup. For one, if new companies can’t market well enough or prove they're different from the next guy, it’s likely to flop. Andrew Chen explains how to avoid that issue in “
The Cold Start Problem
,” which came out today.
Chen includes talks with execs from companies like LinkedIn, Zoom, Uber and more about the network effect and how to work it into new products. The book gets at how many companies don’t fully understand network effects, even though grasping the concept can help them compete and find long-term success. Might be a good Christmas read!
