THE DETAILS BEHIND THE ALGORITHM ARE A CLOSELY GUARDED SECRET

It’s common to find some profiles with a few followers that have videos with thousands of views.” ADVERTISING TO YOUR AUDIENCE That has an impact on advertising — and, like others in the social space, TikTok is still grappling with how to make money out of its 800m users. Alongside the usual video and full-screen ads, there’s also Top View, which shows an ad when the app is opened, making sure it can’t be missed or ignored; all of that can be targeted based on demographics, device, interest and more, says the TikTok spokesperson. Another way for companies to get involved is the Creator Marketplace, which helps brands partner with TikTok creators, tapping into their knowledge of the app and their audiences for marketing. However, the most popular ad format on TikTok is the ‘hashtag challenge,’ a viral marketing system that invites users to participate in contests or make themed videos.

more about each user, watching how they navigate the feed, which videos they skip and which they like, says Williamson. “New videos with fewer engagements are interspersed with other videos that have a large amount of engagement, and TikTok watches the view-to-like ratio closely to determine how quickly to start showing a new video to a wider audience.” That focus on content over connections means a video doesn’t need to have a million views before it’ll be surfaced to users, says Ismael El-Qudsi, CEO of social marketing platform SocialPubli. Instead, it’ll be shown to users if their interests match its hashtags, which are used to describe the video. “The TikTok algorithm is based on the content instead of the number of followers,” El-Qudsi explains. “Each user sees videos related to their interests, no
